Study of GCV, PCV, Heritability and Genetic Advance for Seed Yield and Its Contributing Traits in Mustard (Brassica juncea L.)

Abstract

The results of the study, the harvest index (30.68), biological yield (21.74), and days to maturity (3.30) showed the most genetic variation (GCV). Both the quantity of seeds per silique (17.83) and the seed output per plant (17.06) were moderate. The harvest index (30.71), biological yield (21.74), number of primary branches per plant (8.44), and days to maturity (3.30) all had the highest PCV values. Plant height, the number of siliquae per plant, biological yield, and the length of the major raceme all showed greater estimates of heritability. The number of secondary branches per plant, days to 50% flowering, days to maturity, 1000 seed weight, harvest index, and seed output per plant were all determined to have moderate estimates.
