Abstract
Gelatinization temperature (GT) and gel consistency (GC) are of important traits in determination of rice quality. In present work four rice cultivars namely Sang-e-Tarrom, Gerdeh, IR229 and IRRI2 have been utilized in hybridization as parents. In order to know about genetic characteristics and inheritance of the related traits, direct and reciprocal crosses have been conducted between parents Sang-e-Tarrom and Gerdeh, and between IR229 and IRRI2. Inheritance of related traits have been studied in direct and reciprocal hybridizations for hard, intermediate and soft GC, low and high GT. For these evaluations P1, P2, F1, F2, BC1, BC2 generations and their reciprocal crosses have been utilized in present work. Results showed that gene hard GC dominates on intermediate and soft and also intermediate GT dominates on low. From direct and reciprocal crosses Gerdeh × Sang-e-Tarrom and IR229 × IRRI2 have been illustrated that GC and GT expressions are under monogenic control of one major gene corresponding with several modifier genes. Gene dosage effects play a tremendously important and effective role in segregation production among traits. Regarding to the obtained results selections can effectively be performed in later segregation generations for GC and in early generations for GT.
