摘要
以千重浪2号(23g/1000粒)和润宇1号(30g/1000粒)为试材,在大田条件下研究不同粒重的北方粳稻品种籽粒性状的差异及其与粒重的关系。结果表明,供试品种不同部位谷粒和糙米的面积、长度、宽度、厚度和体积的大小及谷粒充实度的高低均表现出强势粒>中势粒>弱势粒的变化规律,且品种间存在明显的差异;各性状与粒重都呈极显著正相关,小粒型品种和大粒型品种分别是谷壳长度和宽度与粒重的关系密切,而供试品种的谷粒充实度与粒重的通径系数都较大。
The field experiment were carried out with two japonica varieties, Ruyu 1 （30g/1000-grain weight）and Qianchonglang 2 （23g/1000-grain weight）. The results indicated that the length, width, area, thickness, volume and grain plumpness of tested cuhivars were in order of superior grains〉middle grains〉inferlor grains at the mature stage, and there was significant difference between grain characters of two japonica varieties. Correlation analysis showed that the sizes of grain and brown rice characters had a significant positive correlation with the 1000-grain weight. Path analysis showed that there was a close relationship between the grain length and grain weight for Qianchonglang 2, but it was grain width for Ruyu 1. The grain plumpness of tested cuhivars had all a close relationship with grain weight.
