Gene effects for phenol content in Indian mustard (Brassica juncea L. Czern and Coss.)

Abstract

Higher phenol content, in general, is considered as an important factor to impart disease resistance in Brassica species. Therefore, gene effects involved in governing total phenols were studied in six generations i.e. P1, P2, F1, F2, BC1, and BC2, of three crosses in Indian mustard. Both, additive as well as non-additive gene effects figured important. Also, epistatic effects were prominent in most of the crosses studied. Findings of the present study for advocated for inter-mating in segregating generations to accumulate favorable alleles responsible for the genetic control of phenol content. Selection of desirable types in advance segregating generations would be useful in improving phenol content.
