IPM packages tested at several research centres vis-a-vis the farmers’ practices indicate superiority of the former. IPM practices enabled reduction in the number of chemical sprays. IPM system also resulted in increase of natural enemies by three-fold, reduced the insecticide and environmental pollution (Dhaliwal and Arora, 1996).
An integrated strategy for the management of major pests and diseases is possible by
I. breeding new varieties with built-in resistance,
II. evolving efficient methods of pest control through pest surveys and monitoring, and
III. biological control of pests with the help of conservation and augmentation of natural enemies like parasites, predators and insect pathogens.

The use of the term cisgenesis is an attempt to distinguish GM plants or other organisms produced in this way from transgenics that is GM plants that contain DNA from unrelated organisms. Schouten et al. (2006) introduced the term cisgenesis and defined cisgenesis as the modification in the genetic background of a recipient plant by a naturally derived gene from a cross compatible species including its introns and its native promoter and terminator flanked in the normal sense orientation. Since cisgenes shared a common gene pool available for traditional breeding the final cisgenic plant should be devoid of any kind of foreign DNA viz., selection markers and vector- backbone sequences. Sometimes the word cisgenesis is also referred to as Agrobacterium-mediated gene transfer from a sexually compatible plant where only the T-DNA borders may be present in the recipient organism after transformation (EFSA, 2012). The cisgenesis precludes linkage drag, and hence, prevents hazards from unidentified hitch hiking genes (Schouten, and Jacobsen, 2008). Compared to transgenesis, one of the disadvantages shared by cisgenesis is that characters outside the sexually compatible gene pool cannot be introduced. Furthermore, development of cisgenic crops involves extraordinary proficiency and time compared to transgenic crops. Therefore, the required genes or fragments of genes may not be readily accessible but have to be isolated from the sexually compatible gene pool (Holme et al., 2013).
On 16 February 2012, European Food Safety Authority (EFSA, 2012) reported the detail study concerning the safety aspects of cisgenic plants and validated that cisgenic plants are secure to be used in terms of environment, food and feed, similar to the traditionally bred plants. However, the present GMO regulation keeps the cisgenic micro-organisms out from its supervision. The first scientific statement of bringing forth a true plant obtained by cisgenic approach was reported in apple through the insertion of the internal scab resistance gene HcrVf2 influenced by their own regulatory genes into the cultivar Gala, a scab susceptible cultivar (Vanblaere et al., 2011). Barley with improved phytase activity was produced successfully by Holme et al. 2011, through cisgenic approach. Late blight resistant potatoes have developed by cisgene stacking of R- gene (jo et al., 2014).

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Deterioration causes of crop varieties and their control; Maintenance of Genetic Purity during seed Production
1. Deterioration causes of crop varieties
and their control; Maintenance of
Genetic Purity during seed Production
Dr. B.A.Badiger
Assistant Professor of SST
COA,Hanumanamati
2. The main aim of seed production is to produce
genetically pure and good quality seed.
Variety: Is a group of plants having clear
distinguished characters which when reproduced
either sexually or asexually retains these
characters
Introduction
3. Factors responsible for loss of genetic purity
(kadam ., 1942)
Developmental Variation
Mechanical Mixtures
Mutations
Natural Crossing
Genetic drift
Minor Genetic Variation
Selective influence of
Diseases
Techniques of the
Breeder
Breakdown of male
sterility
Improper / defective
seed certification System
4. Developmental Variation:
Seed crop is grown in difficult environmental
conditions
For several consecutive generations the
developmental variations may arise as
differential growth response.
To avoid or minimize such developmental
variations the variety should always be grown in
adaptable area
5. 2. Mechanical Mixtures:
a. Contamination through field – self sown seed or
volunteer plants
b. Seed drill – if same seed drill is used for sowing
2 or 3 varieties
c. Carrying 2 different varieties adjacent to each
other.
d. Growing 2 different varieties adjacent to each
other.
e. Threshing floor
f. Combine or threshers
g. Bags or seed bins
h. During seed processing
it would be necessary to rogue the seed fields at
different stages of crop growth
6. Mutations:
It is not of much importance as the
occurrence of spontaneous mutations
is very low i.e. 10-7.
If any visible mutations are observed
they should be removed by rouging.
7. Natural Crossing:
• It is an important source of contamination in sexually
propagated crops due to introgression of genes from
unrelated stocks/genotypes.
• The extent of contamination depends upon the
amount of natural cross-fertilization
• natural crossing is main source of contamination in
cross-fertilized or often cross-fertilized crops.
• The extent of genetic contamination depends on
breeding system of the species, isolation distance,
varietal mass and pollinating agent.
To overcome the problem of natural crossing isolation
distance has to be maintained.
8. Genetic drift:
When seed is multiplied in large
areas only small quantities of seed is
taken and preserved for the next
years sowing.
Because of such sub-sampling all
the genotypes will not be represented
in the next generation and leads to
change in genetic composition. This is
called as genetic drift.
9. Minor Genetic variation
Some minor genetic changes may occur during production cycles
due to difference in environment.
Due to these changes in the yields may be affected.
To avoid such minor genetic variations periodic testing of the
varieties must be done from breeder’s seed and nucleus seed in
self-pollinated crops.
minor genetic variation is a common feature in often cross-
pollinated species; therefore care should be taken during
maintenance of nucleus and breeder seed.
10. Selective influence of Disease:
• In case of foliar diseases the size of the seed gets affected due
to poor supply of carbohydrates from infected photosynthetic
tissue.
• In case of seed and soil borne diseases like downy mildew and
ergot of Jowar, smut of bajra and bunt of wheat, it is dangerous
to use seeds for commercial purpose once the crop gets infected.
• New crop varieties may often become susceptible to new races of
diseases and that leads to these varieties may become out of seed
production programms.
(Proper plant protection - major pests and diseases)
11. Techniques of the Breeder
• Instability may occur in a variety due to
genetic irregularities if it is not properly
assessed at the time of release.
• Premature release of a variety, which has been
breed for particular disease, leads to the
production of resistant and susceptible plants
which may be an important cause of
deterioration.
– When sonalika and kalyan sona wheat varieties
were released in India for commercial cultivation
the genetic variability in both the varieties was
still in flowing stage and several secondary
selections were made by the breeders.
12. Breakdown of male sterility:
Generally in hybrid seed production if
there is any breakdown of male sterility in
may lead to a mixture of F1 hybrids
Improper Seed Certification
It is not a factor that deteriorates
the crops varieties, but if there is any
lacuna in any of the above factors and if
it has not been checked it may lead to
deterioration of crop varieties.
13. Maintenance of Genetic Purity during seed
Production
Horne (1953) had suggested the following methods for
maintenance of genetic purity;
1. Use of approved seed in seed multiplication
2. Inspection of seed fields prior to planting
3. Field inspection and approval of the Crop at critical stages
for verification of genetic purity, detection of mixtures,
weeds and seed borne diseases.
4. Sampling and sealing of cleaned lots
5. Growing of samples with authentic stocks or Grow-out test
14. Steps suggested by Hartman and Kestar
(1968) for maintaining genetic purity
1. Providing isolation to prevent cross fertilization or
mechanical mixtures
2. Rouging of seed fields prior to planting
3. Periodic testing of varieties for genetic purity
4. Grow in adapted areas only to avoid genetic shifts in the
variety
5. Certification of seed crops to maintain genetic purity and
quality
6. Adopting generation system
15. Safe guards for maintenance of genetic purity
1. Control of seed source :
2. Preceding crop requirement
3. Isolation
4. Rouging of seed fields
5. Seed certification
6. Grow out test
16. Control of Seed Source
Appropriate class from the approved source for
raising a seed crop.
There are four classes of seed from breeder
seed, which are given and defined by Association
of Official Seed Certification agency (AOSCA).
– Nucleus Seed:
– Breeder Seed :
– Foundation Seed:
– Certified seed
18. Preceding Crop requirement :
This has been fixed to avoid
contamination through volunteer plants and
also the soil borne diseases.
19. Isolation :
• Isolation is required to avoid natural crossing with
other undesirable types, off types in the fields and
mechanical mixtures at the time of sowing,
threshing, processing and contamination due to seed
borne diseases from nearby fields.
• Protection from these sources of contamination is
necessary for maintaining genetic purity and good
quality of seed.
20. Rouging of Seed Fields:
The existence of off type plants is
another source of genetic
contamination. Off type plants
differing in their characteristics from
that of the seed crop are called as off
types. Removal of off types is referred
to as roughing
21. The main sources of off types
a. Segregation of plants for certain characters or
mutations
b. Volunteer plants from previous crops or
c. Accidentally planted seeds of other variety
d. Diseased plants
Off type plants should be rouged out from the
seed plots before they shed pollen and pollination
occurs. To accomplish this regular supervision of
trained personnel is required.
22. Seed Certification:
The main objective of seed certification is to make
available seeds of good quality to farmers.
To achieve this qualified and trained personnel from
SCA carry out field inspections at appropriate stages
of crop growth.
They also make seed inspection by drawing samples
from seed lots after processing.
The SCA verifies for both filed and seed standards
and the seed lot must confirm to get approval as
certified seed.
23. Grow-out Test
Varieties that are grown for seed production should
be periodically tested for genetic purity by
conducting GOT to make sure that they are being
maintained in true form.
GOT test is compulsory for hybrids produced by
manual emasculation and pollination and for testing
the purity of parental lines used in hybrid seed
production.
