摘要
本文根据四川盆地的生态条件,提出了选育大穗型杂交组合,以提高杂交水稻穗着粒数和实粒数,增粒增产选育超高产组合的技术路线,并采用复合杂交的方法进行了选育实践,获得了一批大穗型组合,为超高产育种奠定了理论和实践基础。
Based on the ecological conditions of the Sichuan basin, authors offered a technical line that breeding heavy ear typic combination, which was characterized by enhanced spikelets/panicle and plump-seed rate, raising grains and increasing output. Authors bred some high heterorsis restorer lines and high-yield hybrid combinations by distantly related complex hybridization, it laid a theoretical and practical foundation for super high yield breeding.
