摘要
试验将10个品种水稻同一时间种植在相同外界条件中,排除环境差异分析得出,在遗传特性影响下,抗倒性强的品种比抗倒性弱的品种产量高,主要原因是每穗粒数增多。食味综合评价好的品种直链淀粉含有率低,米饭硬度黏度比小,抗倒性差,且均具有显著的相关性。
Ten varieties of rice were planted in the same external conditions at the same time.Eliminate environmental differences,under the influence of genetic characteristics,the yield of varieties with strong lodging resistance is higher than that of varieties with poor lodging resistance.It is mainly caused by the increase of grain number per panicle.The varieties with good overall-eating have low amylose content,low rice hardness viscosity ratio,poor lodging resistance,and all have significant correlation.
