GENETIC STUDIES ON SOME QUANTITATIVE TRAITS IN PEA 1. INHERITANCE OF VEGETATIVE CHARACTERS, YIELD AND ITS COMPONENTS
his study was conducted in Horticulture Research Institute during the period from 2012 to 2015 to study the inheritance of some garden pea economic characters, viz., plant length, number of branches/plant, green pod yield/plant, number of pods/plant and pod weight. Four garden pea cvs., viz, Master, Perfection 57, Prism and Twin were chosen to produce 3 crosses and their reciprocals. Results showed that maternal effect was absence in all studied characters. Over dominance was detected for high number of branches/plant, high green pod yield/plant and high number of pods/plant in all studied crosses. Over dominance or complete dominance was detected for high plant length. High pod weight was dominant in some studied crosses and the opposite was found in the others. Positive heterosis over the better parent was found in all studied crosses for plant length, number of branches/plant, green pod yield/plant and number of pods/plant traits, however, negative heterosis was detected in all studied crosses for pod weight. Minimum number of estimated genes was one for plant length trait, 1-9 for number of branches/plant, 2-3 for green yield/plant, 3-6 for number of pods/plant and pod weight. Broad sense heritability estimates were 79.49%-89.65% for plant length, 75.14%-83.69% for number of branches/plant, 79.44%-90.81% for green yield/plant, 77.30%- 79.91% for number of pods/plant, while it was 30.75%-53.43% for pod weight.
