The document discusses crop ideotypes for various crops including wheat, rice, maize, sorghum, cotton, and more. It defines what a crop ideotype is according to Donald, which is a plant model that is expected to yield greater quantity or quality of a product within a defined environment. For wheat, the ideotype proposed by Donald in 1968 includes traits like a short strong stem, erect leaves, few small leaves, large ear, and presence of awns. Ideotypes proposed for other crops are also summarized.

The term ideotype was introduced by Colin Malcolm Donald (1968)
He defined it as a biological model, which is expected to perform or behave in a predictable manner within a defined environment.
In ideotype breeding, goals are specified for each trait, resulting in a description of a model plant for the traits of interest (Rasmusson, 1987).

Embracing GenAI - A Strategic ImperativePeter 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.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. Ideotype term was given by C.M. Donald (1968)
Ideotype: “A biological model, which is expected to perform or behave in a
predictable manner within a defined environment.”
According to Donald: A crop ideotype is a plant model which is expected to yield
greater quantity or quality of grain, oil or other useful product when developed as
cultivar.
Ideotype Breeding: Ideotype breeding or plant type breeding can be defined as a
method of crop improvement which is used to enhance the genetic yield potential
through genetic manipulation of Individual plant character.
It aims to enhance genetic yield potential by modifying individual traits to their
predefined optimum levels. In ideotype generally morphological traits are included
but physiological, biochemical, anatomical and phonological traits should also be
included, wherever feasible.

4. IDEOTYPE OFWHEAT
1. A short strong stem - It imparts lodging resistance and reduces the losses
due to lodging.
2. Erect leaves - Such leaves provide better arrangement for proper light
distribution resulting in high photosynthesis or CO2 fixation.
3. Few small leaves - Leaves are the important sites of photosynthesis,
respiration and transpiration. Few and small leaf reduces water loss due to
transpiration.
4. Large ear - It will produce more grains per ear.
5. A presence of Awns - Awns contribute towards photosynthesis.
6. Single culm.

6. IDEOTYPE OF RICE
● The concept of plant type in Rice was first introduced by
Matsushima in 1957, and later by Jennings (1964).
The Rice ideal or model plant type given by Jennings consists of
i. Semi dwarf stature.
ii. High tillering capacity.
iii. Short, erect, thick and highly angled leaves.
●
7. IDEOTYPE OF RICE
In 1969, Chandler proposed the ideotype of ‘dwarf rice’as follows –
1. Shorter culm length (100 cm or less).
2. Greater culm diameter
3. Lower relative internode elongation
4. Short erect leaves of medium width.
5. High tillering capacity.
6. More panicles/m2.
7. High (55% or more) harvest index.
8. IDEOTYPE OF RICE
● Janoria (1985) has suggested an alternative ideotype of rice that has been
developed to maximise utilization of available horizontal space and the
resources from the vertical space. The characteristic features of the novel
ideotype include -
1.Taller stature
2. Fewer, tough, non-lodging and all effective culms
3. Upright growth habit
4. Fewer, well spaced, thick, large but stiff leaves able to maintain
erect position
5. Heavy panicles with limited intra plant variation for panicle yield
6. High light transmission ratio and a deep, extensive root system.
9.
10. IDEOTYPE OF MAIZE
In 1975, Mock and Peace proposed ideal plant type of Maize.
1. Stiff-vertically-oriented leaves above the ear
2. Maximum photosynthetic efficiency
3. Efficient translocation of photosynthate into grain
4. Short interval between pollen shed and silk emergence
5. Small tassel size
6. Photoperiod insensitivity`
7. Cold tolerance
8. Long Grain-filling period.
11. In Sorghum improvement has been obtained through the use
of dwarfing genes. In this crop dwarf F1 hybrids have been
evolved which have made combine harvesting possible.
Swaminathan (1972) has listed several desirable attributes of crop
ideotypes with special reference to multiple cropping in tropics and
sub-tropics. These features consist of
1. Better protein quantity and quality.
2. Suitability to mechanization.
3. Photo and thermo insensitivity.
4. High productivity per unit of water.
12. 5. High productivity per day.
6. Crop canopies that can retain and fix maximum
of CO2.
7. Superior population performance.
8. Low photorespiration.
9. High response to nutrients.
10. High photosynthetic ability.
11. Multiple resistances to insects and diseases.
14. This ideotype was proposed by Singh and
coworkers in1974.
1. Plants of short stature (90-120 cm)
2. Compact and sympodial plant habit making
pyramidal shape.
3. Determinate fruiting habit with unimodal
distribution of bolling.
4. Short duration (150-165 days). It reduces cost of
crop management and allows double cropping.
5. Responsive to high fertilizer dose.
15. 6. High degree of interplant competitive ability. (It means the
ability to perform well at closer spacing, i.e. to use the
environmental resources efficiently.)
7. High degree of resistance to insect pests and diseases.
8. High physiological efficiency.
In addition, boll size is proposed to be in between 3.5 to 4 g,
and there should be synchrony of bolling in flush of flowering.
16. This ideotype was proposed by Singh and Narayanan in1993.
1. Short stature (75-80 cm) and compact plant habit.
2. Intermediate growth habit with at least two
monopodia.
3. Few smaller and thick leaves with spares hairiness.
4. Medium to big boll size (3.5 to 4 g).
5. Responsive to nutrients.
6. High degree of resistance to insects and diseases.
7. Synchronous bolling habit.
