- 摘要:
- 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。
- Abstract:
- Fifty soybean cyst nematode(SCN) resistant varieties(lines) were selected and the correlations among growth stage structure，agronomic traits and yield were analyzed. The results indicated that among these varieties，the days of earlier growth stage were about 33~35 days, accounted for 80% of tested varieties; later growth stage were 77~85 days, accounted for 76% of tested varieties; growth duration were 102~123 days, with those in 112~120 days accounted for 80% of tested varieties. Later growth stage and whole growth stage were significantly positive correlated with 100-seed weight, yield and very significantly positive correlated with seed weight per plant. Seed number per plant was very significantly negative correlated with 100-seed weight, the correlation coefficient was -0.4236.
