4. Introduction
• Botanical name: Arachis hypogeae
• Family: Fabaceae.
• Peanut is also called as ground-nut, Monkey-nut,
Earthnut and Mungphali.
• Peanut is a self pollinated and day neutral plant.

5. Economic Importance
• Its seed is rich source of oil, fatty acids, vitamins and
bioactive compounds.
• Seed coat and hull is source of phenolics, flavonoids and
phyto-sterols.

6. Cont..
• It is used as salted peanuts, peanut butter used in
confectionary items.
• Is efficiently used to cure malnutrition which improves
blood circulation and reduces the risk of various diseases.

7. Nutritional Importance
Nutrients Percentage
Oil content 44-55%
Protein content- 30%
Soluble sugars- 8-14%
Carbohydrates 11%
Water 2%

8. Production statistics
Parameters Worldwide Pakistan
Area(ha) 28 million 81.5 thousand
Production (tons) 48 million 94 thousand

9. Problems in Pakistan
• Reduction in yield due to low and erratic rainfall patterns.
• lack of pure seeds.
• Overall market of groundnut is limited because of no
support price mechanism

10. Cont..
• It is just used as roasted peanuts in Pakistan.

11. Rationale of study
Traditional breeding pipeline
Traditionally a variety release time is10 to 15 years.
Cultivars are still limited to 1-2 generations per year under
field conditions.

12. Cont…..
Speed Breeding deals with 7 years of inbreeding.
It helps breeders to advance filial generations
rapidly.
Through Speed Breeding under accelerated growth
conditions, we can produce 4-5 generations of
Peanut in a year.

13. Objectives of study
• To evaluate the potential of rapid generation
advancement through Speed Breeding in peanut.
• To standardize the potting mixture (best suitable) for
rapid generation advancement under speed breeding
glasshouse conditions.

14. Review of literature
Researchers Findings
Watson etal
(2018)
Multiple generations per year was
produced in several crops, such as 3.7
generations in canola, 4.5 in chickpea,
5.3 in barley, and 5.6 in wheat.
Seinivasan etal
(2019)
7,6.2 and 6 generations from early,
medium and late maturing varieties of
chickpea were obtained in a year.
Mobini etal
(2016)
5.3 generations per year had been
obtained in pea plant.

15. Materials and Methods
Experiment will be conducted in Speed Breeding Facility at NARC
with following conditions.
Photoperiod : 22 hours supplemented with LED Grow lights and 2
hours of dark period.
Temperature : 26 ± 3 °C will be maintained through HVAC
Air-condition system
Humidity : 60 ± 10

20. Expected outcomes
• Rapid generation advancement will progress peanut to
anthesis and maturity in less time as compared to the
crops grown under normal conditions.
• Four to five generations will be obtained within a year.
• Best potting mixture for peanut under speed breeding
conditions will be identified.
