摘要
对现行家蚕品种全茧量区间平均数与该区间内各产卵性状的平均数之间的相关和回归的分析,结果:全茧量区间平均数和各产卵性状的相关性,与全茧量的区间数量即全茧量分散程度有关,换言之,与全茧量的集中度有关。对于全茧量较为分散的品种,部分产卵性状与全茧量的相关性达到显著水平,则可以通过直线回归方程,由全茧量来估算有关产卵性状。
Two pairs of current silkworm breeds （Xiafang and Qiubai, and 871 and 872） were divided into different sections according to the whole cocoon weight. The mean cocoon weight and means of opposition characters were subjected to correlation and regression analyses. The results showed that the number of sections, which reflects the dispersion degree of whole cocoon weight, was related to various o- viposition characters. For the breeds whose whole cocoon weight appeared relatively disperse, some oviposition characters were significantly correlated with whole cocoon weight. Therefore, their oviposition characters can be estimated by whole cocoon weight through linear regression equations.
