STUDY OF GENETIC CONTROL OF SOLUBLE PROTEIN IN ROOT NODULES AND SEEDS IN BLACKGRAM (Vigna mungo (L.) Hepper) (Pages : 5 - 8)

The genetic control of soluble protein in root nodules and seeds per plant in four lines of blackgram (Vigna mungo (L.) Hepper) in two different crosses (cross I: 5×21 & cross II: 17×20) were studied separately. Additive-dominance relationships for soluble protein in root nodules in cross II and also for soluble protein in seeds in both of the crosses were non-significant. Potence values were significant in all the cases except for soluble protein in seeds in cross I. Components of variation, D and H for both of the characters and crosses expressed positive and negative values. Negative sign was due to large sampling variation and genotype- environmental interaction. Dominance ratio showed complete to over dominance in negative direction, which indicated dominance towards decreasing parent. The narrow sense heritability, being high mostly, indicated that selection might be fruitful for soluble protein in nodules in cross I and for soluble protein in seeds in cross II. Genetic advance (GA) was negative in most of the cases, but in some cases it showed positive genetic advance. Positive genetic advance in narrow sense for the characters in root nodules in cross I and for the same in seeds in cross II accompanied by high narrow sense heritability was obtained. This indicated that selection of soluble protein in nodules and seeds in these crosses would likely be fruitful in an advance generations. Download
