[目的]探索杂交水稻甬优9号高效栽培的有效技术途径,进一步发挥甬优9号的增产增效潜力.[方法]测定甬优9号44组产量性状数据,利用相关、回归和通径分析方法分析不同产量水平下单季杂交晚稻甬优9号的穗、粒、重结构,研究各因素间的内在联系和对产量贡献的大小.[结果]甬优9号不同产量水平的穗、粒、重均存在显著差异,有效穗与每穗总粒数是两个相互制约的产量因子,各产量因子作用于产量的效应大小依次为:每穗总粒数>有效穗>结实率>千粒重.[结论]稳定有效穗数、主攻每穗实粒数、适当兼顾千粒重,是实现单季杂交晚稻甬优9高产高效栽培的有效技术途径.
[目的]探索雜交水稻甬優9號高效栽培的有效技術途徑,進一步髮揮甬優9號的增產增效潛力.[方法]測定甬優9號44組產量性狀數據,利用相關、迴歸和通徑分析方法分析不同產量水平下單季雜交晚稻甬優9號的穗、粒、重結構,研究各因素間的內在聯繫和對產量貢獻的大小.[結果]甬優9號不同產量水平的穗、粒、重均存在顯著差異,有效穗與每穗總粒數是兩箇相互製約的產量因子,各產量因子作用于產量的效應大小依次為:每穗總粒數>有效穗>結實率>韆粒重.[結論]穩定有效穗數、主攻每穗實粒數、適噹兼顧韆粒重,是實現單季雜交晚稻甬優9高產高效栽培的有效技術途徑.

[Objective]The research aimed to understand the high and efficiency technique in intersubspecific hybrid rice Yongyou NO.9.[Method]We conducted the correlation analysis, regression analysis and path analysis of intersubspecific hybrid rice Yongyou No.9based on the data of its ear, grain and weight at different yield levels.[Result]The performance of ear, grain and weight in Yongyou No.9 showed significant difference among different yield levels. The enhancement of effective ears would restrain the number of per ear total grains. It was found that the direct contributions of main economic traits to yield were determined to be per ear total grains>effective ear>seed setting rate>1000-grain weight[Conclusion]The high-yield and effective cultivation techniques were suggested as follows: on the basis of certain effective ear number, grain number per ear should be mainly focused with a consideration to 1000-grain weight.
