Abstract:
This study explores genetic regularity of protein and oil content across different genetic backgrounds, which aimed at providing a theoretical basis for developing effective breeding programs. Two BC3F2 populations were made a cross between Dongnong 47 and Hongfeng 11, Zaoshu 18 through hybridization twice and backcross three times, and thus protein content, oil content, 100-seed weight and other agronomic characters were analyzed. The results showed seed protein and oil content of the two backcross populations were different, and the performances of the two backcross populations behave consistency. Correlation analysis showed that seed protein and oil content of the two backcross populations wasn’t correlated with protein and oil content of the parents and difference between parents, respectively, while positively correlated with the mean between parents. Hence the mean between parents used to predict protein and oil content of two backcross populations would be more accurate. Correlation analysis showed that 100-seed weight and plant height were index as indirect selection for breeding varieties with high protein and oil content. The results of the study indicated that higher differences and mean between parents were valuable in high oil or protein breeding.
