Stability analysis of grain yield and its contributing traits in advanced mutant lines of sorghum [Sorghum bicolor (L.) Moench]

Published on

In the present study, 23 sorghum genotypes comprising 17
advanced mutant lines (M5) and six check varieties were
evaluated for stability parameters over four locations during
rabi 2017-18. Based on the ten morphological and yield
traits, pooled ANOVA showed significant differences for
the quantitative traits except for seed yield per plant. Mean
sum of squares due to E+ (GxE) was significant for most of
the characters except for days to flowering, and 100 seed
weight. Environment component showed significant values
for all traits. The GxE (linear) showed non-significant
interaction for most of the characters in this study except
for plant height, panicle length and seed yield. J-12 and J-
3 mutants had mean value more than population mean and
coefficient of regression near to unity and adapted to all
