dc.description.abstractSix generations (P1, P2, F1, F2, B1 and B2) of two crosses viz. RH 0115 (S) x EC 126745 (R) and RH 0120 x EC 126745 (R) were raised in randomized block design with three replications during the year 2006-2007 in normal sown (E1) and late sown (E2) environments to study the inheritance of white rust resistance, nature and magnitude of gene effects involved in the genetic control of seed yield and its attributes and relationship between white rust resistance and biochemical parameters. Disease intensity data was analysed by using χ2-test whereas, yield and its attributes and biochemical parameters were analysed by using generation mean analysis as per Hayman, 1958. White rust resistance was governed by single dominant gene. Correlation studies indicated the positive association of sugars with disease intensity whereas, negative association was observed between phenols and disease intensity. Seed yield and its attributes were found to be predominantly under the control of additive gene effects except main raceme length and seed yield per plant whereas, non-additive gene effects were predominant in case of biochemical parameters. Duplicate type of epistasis was frequent for biochemical parameters whereas, it was less frequent for seed yield and its attributes.en_US
