| 摘 要： | 通过对影响杂交稻组合泰丰优2098产量性状的相关分析、逐步回归分析及通径分析,结果表明:产量构成四要素与产量之间都呈正相关,对产量贡献率依次为有效穗数跃穗粒数跃结率实跃千粒重,有效穗数影响最大,结实率和穗粒数对产量也有较大的影响。因此,生产上在确保足够有效穗的前提下,适度促大穗,增加谷粒充实度提高千粒重,以获得高产。

| Abstract: | Correlation analysis,stepwise regression analysis and path analysis of yield traits of hybrid rice Taifengyou 2098 were studied. Results indicated that production constitute four elements was positively correlated with production,production contribution rate was in the order of effective spike number＆gt;spike grain number＆gt;knot rate real＆gt;thousand grain heavy,effective spike number had maximal effects,strong rate and Spike grain number also had great effects on production. Therefore,on the premise of ensuring a sufficiently effective spike number in production,moderately large Spike and increased grain plumpness to raise thousand-grain weight and get high yield. |
