摘要
利用福寿螺的１０个近交系作增广ＮＣⅡ交配试验。对形态性状和重量性状进行发育阶段性观测。根据遗传率、遗传相关和相关遗传率及其通径分析结果，探讨了提高腹足产量的间接选择方法。
The augmented north carolina Ⅱ mating design was conducted with 10 inbred lines of Ampullaria gigas. The morphological and body weight characters were measured in each of four growth development stages. Based on the heritabilities,genetic correlations, and correlative heritabilities and their path analysis, the indirect selection for proleg weight was researched.
