Description :
Cowpea [ Vigna unguiculata (L.) Walp.] known as ‘Labia’ and in Marathi known as Chavali It belongs to
family Fabaceae. Cowpea is one of the most important pulse crops in India. It contains carbohydrates,
proteins, fats, vitamins and minerals. The seeds are major source of dietary protein in most developing
countries. The seeds of Cowpea var. Phule Pandhari (9708) were treated with 0.050%, 0.075%, 0.10%
and 0.125% and Ethyl methane sulphonate and another lot of seeds were exposed to different doses
20 kR , 30 kR , 40 kR and 50 kR of gamma rays and combination of both EMS and Gamma
rays.Statistical analysis of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation
(GCV), heritability (h2) and genetic advance (GA) for Plant height, Number of pods per plant, Length of
pod, Number of seeds per pod, 100 seeds weight was carried out. Induced variability was calculated in
following treatments of EMS and gamma rays in seven different yield-contributing traits of Cowpea in
the M2 generation. Plant height showed maximum phenotypic coefficient of variation (31.9670) followed
by number of pods per plant (17.2426), 100 seed weight (14.4367), length of pod (6.3240), number of
seeds per pods (5.3409).
