Estimates of heritability and genetic advance for different attributes in Indian mustard (Brassica juncea L.)

Abstract

High heritability and genetic advance for 12 characters (days to flowering, number of primary branches per plant, number of secondary branches per plant, length of main fruiting branch, relative water content in leaf, seed weight per plant, dry matter per plant, harvest index, test weight, oil content, erucic acid content in oil and protein content in seed) were studied in C.S.A.U. University of Agriculture and Technology, Kanpur (U.P.) in Rabi using 10 diverse genotypes of Indian mustard, 45F hybrids and 45F 2 1 hybrids for generation mean analysis.The characters like high heritability coupled with high genetic gain for test weight and moderate heritability and moderate genetic gain for erucic acid content in oil and harvest index. This indicated that these characters are probably governed by additive genes, selection which is likely to be beneficial in improving these characters.
