选取50份抗线大豆品种(系)进行生育期结构与农艺性状及产量关系的相关性分析。结果表明:(1)供试的抗线品种(品系),生育前期天数主要集中在33~35 d,占供试材料的80%;生育后期天数主要集中在77~85 d,占供试材料的76%;全生育期天数在102~123 d之间,其中112~120 d的占供试材料的80%;(2)生育后期、全生育期R8与百粒重、小区产量均呈显著正相关,与单株粒重呈极显著正相关;(3)单株粒数与百粒重之间呈极显著负相关,相关系数为-0.4236。
The correlation analysis of the relationship between structure and agronomic traits and yield of 50 lines of resistant soybean was conducted. The results showed as follows: (1) The resistant varieties (lines) tested in the early days of growth mainly concentrated in the period of 33-35 d, accounting for 80% of the tested materials; the days of later growth mainly concentrated in 77-85 days, Of the total growth period was between 102 and 123 days, of which 112 to 120 days accounted for 80% of the tested materials; (2) R8, 100-grain weight and plot yield of the whole growth period were all significant (P <0.05). (3) There was a significant negative correlation between grain weight per plant and weight per plant, with a correlation coefficient of -0.4236.
