通过对早籼常规品种与优质品种（系）的性状比较结果表明，穗部性状、碾米品质和外观品质等１９个性状，有１７个性状存在显著差异，其中有５个穗部性状和碾米品质中的整精米率，常规品种显著高于优质品种（系），外观品质性状优质品种（系〕均极显著优于常规品种．通径分析表明，影响单株籽粒产量的遗传因素的重要性依次为每穗实粒数＞单株有效穗数＞结实率＞千粒重；环境因素的重要性依次为单株有效穗数＞每德实粒数＞结实率＞着粒密度。影响糙米率、精米率和整精米率的遗传因素主要是谷粒的形状，其次才是垩白。
By comparing the traits of conventional indica indica varieties and high quality cultivars (lines), the traits of panicle traits, rice milling qualities and appearance qualities showed that there were 17 traits significant differences among which there were 5 traits and grind The milled rice rate of rice quality was significantly higher than that of the high-quality varieties (lines), and the quality varieties (lines) of the appearance quality traits were significantly better than the conventional varieties.The path analysis showed that the genetic factors affecting the grain yield per plant were important The order of the number of grains per spike> the number of panicles per plant> the rate of seed setting> the grain weight per thousand; The importance of environmental factors were in turn the number of panicle per plant> the number of seed per gram> the rate of seed setting> The genetic factors of milled rice rate and milled rice rate are mainly the grain shape, followed by the chalkiness.
