摘　　要：通过对Ⅱ优039产量及其构成因素进行相关分析和通径分析,结果表明:各因素与产量均呈正相关,达极显著水平;每穗总粒数和有效穗对产量的贡献较大。因此,在高产栽培技术上要主攻有效穗和每穗总粒数,实现足穗大穗,并在此基础上,努力增加粒重,以获得高产。Correlation and path analysis among grain yield and its components for a hybrid rice combination II You 039 were studied by using the data from rice varietal regional test of Fujian province from 2006 to 2007. The results showed that there was a highly significant positive correlation among grain yield and its componnets. Total spikelets per panicle and effective panicles had larger contribution to grain yield. Therefore, in order to achieve high grain yield, high- yielding cultivaton techniques must improve effecitve panicles and total spikelets per panicle for ensuring sufficient panicles and large spike, and then increase 1000-grain weight.
