【摘要】 以17个双低优质甘蓝型油菜品种(系)为材料考察了主要生物学性状及其与产量间的相关关系。结果表明,单株产量与植株叶面积指数及主花序长度呈极显著正相关,而与茎粗、叶片数、株高及有效分枝部位相关不显著;在生物学性状之间,叶片数与主花序长度间呈显著负相关,株高与有效分枝部位间呈极显著正相关。更多还原

【Abstract】 Seventeen double low elite varieties were involved in the experiment,the correlation of major biological characters and yield of rapeseed were studied The results showed that yield per plant had a significant positive correlation with leaf area index and main inflorescence length, but had no significant correlation with stem diameter, blade number, plant height and available branching portion Among biological characters, blade number had a significant negative correlation with main inflorescence length, and plant height had a significant positive correlation with available branching portion更多还原
