Inheritance of days to flowering and rust resistance in Pea

Abstract

The present investigation of inheritance of days to flowering and resistance to rust in peas was conducted at Pili Kothi from Tilakdhari P.G. College, Jaunpur during Rabi season 2009-10. F2 and F3 generation of Arkel x JPBB-3 and Bonnevilla x JPBB-4 were utilize for determining the inheritance of days to flowering and resistance to rust respectively. Arkel was an early rust susceptible variety, Bonneville, late and rust susceptible variety and JPBB-3 and JPBB-4, late and rust resistant cultivar. Days to flowering was govern by a single gene, late not being dominant over earliness. Inheritance date on reaction to rust was in consistent over the generation and also in term of nature of dominance. The number of gene varied from 1 to 2 over the crosses.
