GENETIC STUDIES ON SOME QUANTITATIVE TRAITS IN PEA 2. INHERITANCE OF NUMBER OF DAYS TO FLOWERING AND SOME POD CHARACTERISTICS
this 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., number of days to flowering, pod length, number of seeds/pod, seed weight and shelling percentage. 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 and complete dominance was detected for high shelling percentage. Complete dominance towards high parent and absence of dominance were found on number of seeds/pod. Partial dominance was detected for late flowering parents in all the studied crosses. High pod length and high seed weight were dominant in some studied crosses and the opposite found in the others. Positive heterosis over the better parent was found in all the studied crosses for number of days to flowering (based on the early flowering parent) trait, meanwhile, Negative heterosis was detected in all studied crosses for pod length and seed weight traits. For number of seeds/pod and shelling percentage traits, positive hetrosis was found in one cross and the opposite was found in the other. Minimum number of estimated genes was one for number of days to flowering, number of seeds/pod and shelling percentage traits, while it was 3-18 for pod length and 1-6 for seed weight. Broad sense heritability estimates were 93.47%-94.74% for number of days to flowering, 31.47%-66.38% for pod length, 29.22%-59.78 for number of seeds/pod, 23.88%-42.23% for seed weight and 41.41%-58.42% for shelling percentage.
