The nature of inheritance and type of gene action governing nutritional traits are complex, hence a better understanding of the factors that contribute to the overall grain quality of rice will lay the foundation for developing new breeding and selection strategies for combining high quality with high yield. The present investigation was carried out to understand the gene action and inheritance of yield and nutritional quality traits in rice.
Crosses were effected with ten parents in diallel fashion without reciprocals during kharif, 2014, in the next rabi 2014-15 itself, all the 45 F1s without reciprocals along with parents and two check varieties were grown for producing sufficient F2 seed. The data obtained from F1s and parents were analysed as per Method II (F1s + parents) and Model - I (fixed effect) of Griffing (1956) for combining ability.
In the present study, cross combinations viz., WGL-32100 × DRR Dhan-40, Ramappa × RP-Bio-5478-176 for intermediate amylose, WGL-32100 × Ramappa for high protein content, MTU 1010 × RP-Bio-5478-166, WGL-32100 × RP-Bio-5478-166 for iron concentration and RP-Bio-5478-166 × DRR Dhan-40, for zinc concentration were identified as the top ranking ones for further advancement.
