Abstract:

Eight high yielding rice genotypes along with their twenty eight crosses which effected in a diallel fashion excluding reciprocals were subjected to combining ability which aimed at elucidating the genetic system underlying the inheritance of yield and quality traits. The study revealed predominance of non-additive gene action for most of the yield components and quality traits except straw yield/plant, which was under the control of additive gene action. NLR 40024, MTU 1075 and HKR08-62 were identified as good general combiners for grain yield/plant, panicle length, panicle weight, straw yield/plant, harvest index, head rice recovery, kernel length after cooking, water uptake and alkali spreading value. The crosses Kavya × HKR08-62, Gontrabidhan × HKR08-62, Kavya × MTU 1075 have shown significantly favorable SCA effects for grain yield, yield components and quality traits. Majority of the crosses with high SCA effects involved with high × low combinations indicating additive × dominance, dominance × dominance type of gene interactions for expression of traits. To explore both additive and non-additive type of gene action, biparental mating among selected crosses or use of selection procedure such as diallel selective mating may be followed.
