摘要： 研究先后引进了33个杂交稻新组合，在6个试点开展了9组单季杂交晚稻新组合的比较试验，从中筛选出了丰产性、抗逆性和品质等综合性状较好的两优培九新组合。同时，明确了两优培九在台州作单季晚稻种植的特征特性，并利用通径分析的方法，分析了两优培九不同产量水平的穗、粒、重结构，研究提出了其高产高效栽培技术。

Abstract: New combination Liangyou Peijiu was selected by introducing 33 hybrid rice combinations and comparing test on 9 groups of single cropping late hybrid rice combinations in 6 testing sites. Moreover, the characteristics of Liangyou Peijiu grown as single cropping in Taizhou was made clear. The study on constitutions of panicle,grain and grain weight in different yield levels of Liangyou Peijiu was conducted by path analysis. The high-yielding and high-resulting cultural techniques were promoted.
