Abstract:

Hayman diallel analysis was performed excluding reciprocal in Indian mustard, the experimental material consisted of morphological diverse but genetically homozygous genotypes/varieties and their 45 direct crosses i.e., the F1 populations. The traits days to flowering, days to maturity, plant height, number of siliquae per plant, 1000-seed weight, harvest index, and linolenic acid explored additive type of gene effects. The correlation between parental order of dominance (Vr + Wr) and parental mean (Yi) was positive and significant for days to flowering, days to maturity, plant height, number of siliquae per plant, seed yield per plant, 1000 seed weight and erucic acid which indicated involvement of recessive alleles for increasing a value of respective traits. Whereas dominant genes were involve in increasing number of branches per plant and oil content. Based on comparison of both Griffing and Hayman approaches revealed over dominance for all the characters. The Hayman s’ analysis was found invalid due to significant values of t2 for number of siliquae per plant, seed yield per plant, oleic acid, linoleic acid and erucic acid. In these cases, Griffing analysis showed over dominance.
