Genetic analysis of quantitative traits in mungbean

Abstract

The experiment comprising 28 F, and 8 parents was laid out in a randomized block design with three replications. Observations were recorded on days to flower and maturity, plant height, number of primary branches, number of pods per plant, number of grains per pod, pod length, 100-grain weight, yield per plant and protein content. Components of genetic variance were worked out through diallel cross analysis excluding reciprocals. Dominant alleles were more frequent for most of the traits. Positive and negative alleles among parents were distributed asymmetrically for all the characters; one or two major gene groups controled the characters. Additive and non-additive gene actions were found important in the inheritance of most of the traits.
