Abstract
Five female parents viz, ICPL 85063, MRG 66, LRG 30, LRG 41 and Nallakandi (local popular cultivar) and ICPL 87119 as male parent were selected and crossed to study the inheritance pattern of reistance to Fusarium wilt. The F2 population of crosses LRG 30 x ICPL 87119, MRG 66 x ICPL 87119 and ICPL 85063 x ICPL 87119 segregated into a 13 R: 3 S. When back crossed with resistant parent ICPL 87119, it segregates in a 3R: 1S phenotypic ratio, and with susceptible parent, it segregated into a phenotypic ratio of 1R: 1S. LRG 41 x ICPL 87119 and Nallakandi x ICPL 87119, F2 population segregated into a ratio of 9R: 7S. The back cross population B1 to the susceptible parent in both the crosses segregated in the phenotypic ratio of 1 R: 3S and to the resistant parent segregated in the ratio of 3R: 1S. Inheritance studies on Fusarium wilt resistance affirmed the dominance of resistance to susceptibility and the role of two gene interactions viz., inhibitory (13:3) and complementary (9:7) types.
