Understanding of Gene Action for Nutritional Traits in Elite Rice (Oryza sativa L.) Crosses

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