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。
Thirteen agronomic traits of the 23 tumorous stem mustard cultivars studied in this study were classified into four typical traits related to yield, yield factors, morphological numbers and growth period. The results showed that the typical correlation between yield and yield was higher than the correlation with growth traits and the correlation with morphological traits. The correlation between yield factors and morphological quantity was higher than those related to growth traits and higher than the correlation between morphological quantity and growth traits. The results of canonical variable analysis indicated that no matter which two trait groups, the main function of the correlation was the plant fresh weight, the diameter of the tumor stem and the swelling of the tumor stem.
