查询词典 heterosis

It was suggested that the capacities of parthenogenesis and apogamy of rice were used to obtain stable lines in early hybrid generations.And several characteristics such as apomixis,cleistogamy,superior genes of qualities and resistance to disease and pest were combined and were used to search a new pathway of selecting high yield,superior quality and heteroresistance to diseases and pest,and lead to realize the purpose of fixing heterosis by apomixis.
