以通杂108、通杂126为材料,分析了在不同灌水时期处理下产量及与产量有关的穗长、穗重、穗粒重、千粒重等农艺性状的关系,结果表明:4个处理均比CK增产,差异均达极显著水平,两品种产量及不同灌水时期间产量差异达极显著水平;穗重、穗粒重与产量呈极显著正相关,从直接通径系数分析来看,穗粒重对产量的直接通径系数最大,穗重通过穗粒重对产量影响的间接通径系数正向最大.
With the hybrid 108 and hybrid 126 as materials, the relationship between the yield and yield-related panicle length, spike weight, spike weight, grain weight per spike and grain weight per spike was analyzed. The results showed that the average ratio of four treatments CK increased significantly, the difference reached an extremely significant level, the yield difference between two cultivars and different irrigation periods reached extremely significant level; spike weight, spike weight and yield were significantly and positively correlated, from the direct path coefficient analysis, spike The direct path coefficient with the highest yield to yield and the indirect path coefficient with spike weight through yield of grain weight were the highest.
