摘要
本文将所研究的23个茎瘤芥品种13个农艺性状归成产量、产量因素、形态数量以及生育期等四组性状进行了典型相关分析。结果表明:产量与产量因素的典型相关高于与生育期性状的相关,又高于与形态数量性状的相关。产量因素与形态数量间的相关高于与生育期性状的相关,又高于形态数量与生育期性状间的相关。典型变量分析结果指出无论是哪两个性状组间,在关联上起作用的主要有株鲜重、瘤茎横径和瘤茎膨大期。
The relationship among agronomic characters in 23 tumorous stem mustard local varieties was studied. The 13 agronomic characters studied were grouped into yield,yield-component characters, morpho-quantitative characters and that with developmental-period characters. The results showed that the canonical correlation of yield with yield-component characters was higher than developmental-period characters, and in turn, than that with that morpho-quantitative characters. Correlation between yield-component characters and morpho-quantitative characters was higher than that between yield-component characters and developmental-period characters, and in turn,than that between morpho- quantitative characters and developmental-period characters. The canonical variable analysis indicated that, the important effect was observed in whole plant fresh weight ,horizontal length and developmental duration in correlative association.
