【摘要】 以34个水稻品种或品系为试材,对产量、产量构成因素、穗部性状、叶部性状等进行了研究。结果表明:品种间产量差异极显著,辽盐188、龙盘5号、沈稻9号、辽盐158、沈稻9810等产量较高。产量与成粒率呈显著的正相关,与每穗秕粒数呈显著的负相关,与倒2叶长、倒3叶长也呈显著的负相关。更多还原

【Abstract】 Using 34 cultivars as materials,grain yield,yield components,panicle and leaf traits were studied.The results indicated that the yield difference between cultivars was significant.The yields of Liaoyan 188,Longpan 5,Shendao 9,Liaoyan 158,Shendao 9810 and so on were higher.There was a positive correlation between the yield and percentage of ripened grains.But the yield were negative correlated with the percentage of shrivel kernels,length of second leaf and length of third leaf from above.更多还原
