Abstract:

Observations on parent lines, F2 and F3 lines were recorded when the susceptible check, TN1 shown complete susceptibility to BPH. Scoring for BPH reaction was done following the guidelines of Standard Evaluation System for Rice (IRRI, 1998). The male parent IR64 showed resistance to BPH with score 1.33 where as the female parent CG Zn Rice I showed susceptibility with a score of 9.0, the female parent Muskan showed susceptibility with a score of 6.7 and another female IET22290 showed susceptibility with a score of 7.0 under glasshouse conditions. The resistant check, PTB33 showed complete resistance with a score of 0, and susceptible check, TN1 exhibited complete susceptibility with 9 as score. Genetics of BPH resistance in F2 and F3 population derived from CG Zn Rice I x IR64 for BPH resistance show Mendelian segregation. They show 3:1 and 1:2:1 segregation ratio in F2 and F3 respectively possess only single dominant gene for resistance which is indicated by 3:1 (3 resistant: 1 susceptible) segregation observed in F2 generation. This is also supported by F1 showing resistance and classification of F3 progenies in the ratio of 1: 2: 1 (1 breeding true for resistance: 2 segregating for resistance and susceptibility: 1 breeding true for susceptibility).This confirmed the inheritance of a single dominant gene present in these resistant parent IR64.
