| 摘 要： | 对150份水稻品种资源的主要农艺性状进行了鉴定，并进行了初步的分析与评价，结果如下：（1）供试品种的株高主要分布在中和中高两个类别，分蘖以分蘖力中等和分蘖力强类型为主，绝大多数品种都能抗倒伏。（2）不同品种间剑叶和倒二叶的叶长、叶宽的差异比较明显，剑叶和倒二叶角度以直立型为主。（3）供试品种的以短穗长为主，穗粒数以中类型为主，有效穗数以少、中两个类型为主，大多数品种的结实率都很高，着粒密度较大，千粒重处于中等水平。不同品种在穗长、穗粒数、有效穗数和着粒密度等性状品种间差异明显，结实率和千粒重变异较小。

| Abstract: | In this study, 150 rice variety resources had been carried on the appraisal of main agronomic traits. The appraisal results also had been analyzed and evaluated preliminarily. The research results were as follows： （ 1 ） The plant height of tested varieties are mainly distributed in the medium and high category. Tillering type were mainly distributed in the medium and strong category. Most of the varieties were resistance to lodging. （2） Leaf length and leaf width of flag leaf and the pour two leaf had obvious differences in different varieties, flag leaf and pour two leaf were mainly upright-type. （ 3 ） Panicle length was mainly short spike type, grain number per panicle spike grain was mainly medium type, the effective panicle was mainly in the two types of few and medium type. Most of the varieties maturing rate were very high, the particle density were bigger, and the thousand seed weight were in medium level. Spike length, spike grain number, effective panicle number and grain density appeared to be obviously differences among different varieties, while the variation of maturing rate and thousand seed weight were smaller. |
