大豆品种生育期、百粒重、产量间的相关研究

Correlation Analysis among Growth Period,100-seed Weight and Yield of Soybean

通过对238份大豆区试、品系鉴定和产比试验品种的开花期、结荚鼓粒时间与百粒重关系的分析表明：安阳地区种植的大豆开花期在7月22日到8月3日之间，其中以7月26日到7月31日的较多，占供试材料的78．15％；结荚鼓粒时间在62—71d之间，以64～67d的品种最多，占供试品种的82．8％；开花期和百粒重的相关系数r=-0．317；结荚鼓粒时间与百粒重呈显著正相关，r=0．642。

The blooming stage, pod -filling period and 100 -seed weight of 238 soybean varieties （lines） were researched in regional test, strain identification and yield comparison test. The results showed that the blooming stage of the soybean varieties （lines） in Anyang region was between July 22nd and August 3rd, and most were between July 26th and July 31st, which occupied for 78.15%. The pod - filling period was 62 -71 days, and most were 64 -67 days, which occupied for 82.8%. The correlation coefficient between the blooming stage and 100 -seed weight was -0.317, while that between pod -filling period and 100 - seed weight was 0.642 （ P 〈 0.05 ）.
