Its whole plant exhibited yel- low-green trait at the seedling stage, and gradually changed into pea green from the tillering stage. Compared with its wild-type par- ent 10079, at the seedling stage, the contents of chlorophyll a, chlorophyll b, and carotenoid decreased by 45.03%, 53.93%, and 39.56%, at the maturation period, the number of spikelets per panicle reduced by 9.45%, the 1000-grain weight decreased by 10.76%, respectively.
