外源DNA导入花生变异体后代的数量性状分析

Quantity Characters Analysis of Peanut Variation Progeny Influenced by Exotic DNA

方法:对外源DNA导入花生变异体的D8代株行进行了数量性状的比较、相关性分析和聚类分析。结果:①来自D4代同一株行的10个D8代株行相比较,主茎高、侧枝长、总分枝数等性状无显著差异,叶长、果长及果皮厚三个性状差异显著或极显著;②单株生产力与其他性状的相关程度不同,与果长呈极显著正相关,与主茎高呈显著负相关;③将10个株行聚为3类,结果与系谱图并不完全一致。

Through the quantity characters comparison, correlation coefficient analysis and cluster analysis based on agronomic characters observa tion both in field and in laboratory on Ds generation of peanut variations, we drew the conclusions as follows. First, the main stem height, the lateral branches length and thle total No. of branches had no significantly difference comparing the 10 plant lines came from D4 generation, but the length of leaves, the length of pods and the favors of the pods husk had significantly difference. Second, the productive of per plant had different correlative with different characters, which had positive correlations with the length of pods, but had negative correlations with the main stem height. Third, the 10 plant lines can be classified to 3 types, but the result didn＇t consistent with the family trees.
