Gene action and combining ability for yields and quality traits were analyzed by line x tester analysis in 48 crosses along with 8 lines and 6 testers to find out their usefulness in improvement of quality traits. Analysis of variance revealed that ASD 16 line and Pusa Basmati 1 and Basmati 370 testers were the good combiners for both yield and quality traits. The crosses ADT 36 / GEB 24, ASD 16 / Pusa Basmati 1, ADT 43 / Jeeragasamba, MDU 2 / Pusa Basmati 1 and MDU 5 / Improved White Ponni were identified as the good specific combiners for grain yield and some other quality characters. Dominance gene action was found to be predominant for most of the quality characters along with yield giving way for exploitation of heterosis breeding for meeting out the increasing quality preference of the consumers.

Combining Ability Analysis

An investigation was undertaken to assess the combining ability for yield and quality traits in rice. Three WA cytoplasmic male sterile lines of rice i.e., IR-58025A, IR-68897A and Pusa 6A were crossed with six restorer genotypes i.e., Sanwal Basmati, Pusa Sugandh-2, Pusa Sugandh-3, Pusa Sugandh-5, Pusa 2517-2-51-1 and HURJM- 59221 in line x tester design to generate 18 hybrids. Among the female parents, IR-58025A revealed significant desirable value of GCA effect for yield per plant and most of the quality traits. Among the pollen parents, Pusa Sugandh-3 revealed significant desirable value of GCA effect for most of the yield traits. However, Pusa Sugandh-5 revealed significant desirable value of GCA effect for most of the quality traits. Pusa 6A x Pusa Sugandh-2 evinced the highest significant value of SCA effect for grain yield followed by IR-58025A x Pusa Sugandh-5. However, IR- 68897A x Pusa 2517-2-51-1 followed by IR-58025A x Sanwal Basmati revealed the significant desirable value of SCA effect for most of the quality traits. For both yield and quality traits, IR-58025A x Pusa Sugandh-5, IR-68897A x HUR-JM-59221 and Pusa 6A x Pusa Sugandh-2 were found to be relatively better performing. Thus, present study aims to develop hybrids performing better for both yield and quality traits.

Additive Component

To know the extent of heterosis among the selected 21 crosses derived from the diallel mating system using seven parents regarding yield and quality traits. The magnitude of heterosis was high for grain yield and protein content and moderate to high for plant height, ear bearing tillers per plant, number of primaries per panicle, L/B ratio, head rice recovery and GT score. The best heterotic crosses for grain yield were erramallelux NLR 33637 and IR 72 x NLR 33637. The high heterotic effects in the hybrids may be due to predominant role of non additive component in the inheritance of the characters studied.
