INHERITANCE OF PHENOLS AND PROTEIN IN RELATION TO WHITE RUST (ALBUGO CANDIDA) RESISTANCE IN INDIAN MUSTARD

Abstract

Studies on the relationship of phenols and protein with white rust severity showed that phenols imparted resistance whereas more protein led to higher disease severity at vegetative and reproductive stages in Indian mustard. Inheritance studies indicated the importance of both additive and dominance components of variance, with the preponderance of latter, in the genetic control of phenols and protein. Genotypes EC126743, EC 126745, Domo-4 and EC 126746-1 were identified as good combiners. Six crosses have been identified on the basis of their high SCA effects and per se performance for further studies.
