GENETIC ANALYSIS FOR QUALITY TRAITS AND POWDERY MILDEW INCIDENCE IN BIPARENTAL PROGENIES OF GARDEN PEA

Genetic components of variance for quality traits (total soluble solids, ascorbic acid and protein) and powdery mildew incidence were calculated from progenies derived by intermating F2 plants in two intervarietal crosses, Arkel x VG 5 and Lincoln x VG 5 of garden pea.

Analysis of variance revealed highly significant differences among the biparental progenies with respect to these characters in both the crosses.
The magnitude of dominance component was significantly higher for all the characters in both the crosses and the average degree of dominance was in overdominance range.
The studies indicated that a biparental approach could be adopted for enhancing genetic variability.
The results are discussed in relation to usefulness of biparental mating in pea breeding.
