Genetic Variability in Chenopodium.
Abstract
Coefficient of variability and genetic gain for seed yield and its 10 contributing traits was worked out in 44 germplasm lines of Chenopodium spp. in the year 2000–2001 at National Botanical Research Institute, Lucknow. Seed yield/plant ranged from 2.17–97.97 g with an average yield of 34.99±1.l8 while leaf size ranged from 1.42–178.77 cm2 indicating great diversity among the strains involved in the present study for these traits. Phenotypic coefficient of variation and genotypic coefficient of variation was maximum for leaf size, followed by dry weight of plant and 100 seed weight. The heritability estimates were high for all the traits, which also confirmed a great amount of variation in the lines under study. Genetic gain was high for all the traits except days to flowering and days to maturity, which indicated that all the traits were mainly governed by additive gene effects. A breeding plan was discussed to enhance the yield potential.
