Abstract:

In order to identify genetics laws of carotenoids in wheat grains, which is the important nutrients and health chemicals, seven wheat varieties with different carotenoid content were used to make 21 cross combinations according to Griffing diallel cross Ⅱ. Furthermore, the combining ability, genetic model, dominant and recessive genes and genetic parameter estimation were analyzed. The results showed that Shengxuan No.2 was an excellent parent material with high carotenoid content in grains and good general combining ability, which could rapidly produce the carotenoid content of hybrids. It is necessary to choose high content parents × medium content parents in parent selection and cross. The inheritance of carotenoid content in wheat grain followed additive-dominant-epistatic model. In addition, the high value of carotenoid was controlled by recessive gene with low heritability. Therefore, strict selection should be carried out in the higher generation to select new lines with higher carotenoids content in wheat nutrition and health quality breeding.

Key words: wheat, carotenoid content, Griffing diallel cross Ⅱ design, inheritance, nutrition and health quality
