摘    要:1997年度江苏省杂交中粳稻区试结果表明:(1)参试的杂交中粳稻,其杂种优势主要体现在穗、粒等穗型指标上,而穗数等群体指标和结实率明显低于武育粳3号;(2)各产量因素对环境变化的反应不一,其平均变异系数大小顺序为;穗数>每穗实粒数>结实率>每穗总粒数>千粒重;(3)综合丰产性和稳产性分析,泗优418不仅产量高,而且稳产性好。

关 键 词:杂交粳稻  优势  稳定性

Abstract:The results of the medium hybrid japonica rice regional test ofJiangsu province in 1997 showed as follows. (1) The tested hybrid japonica rice hassignificant heterosis in spike type index such as spikelets and grains, but much lessthan those of rice variety Wu-Yu-Jing No. 3 in the number of panicle and settingpercentage. (2) The reaction of each yield factor to environment is different. Theorder of average variation coefficient is the number of panical>the number of filledspikelet /panical > setting percentage > the total number of spiketlet /panical >1 000-grain weight. (3) Based on the analysis of yield performance and stability ofhybrid japonica rice in the regional test, the Siyou 418 is high and stable in yield.
Keywords:hybrid japonica rice  heterosis  stability
