对45个苦养品种的6个主要经济性状进行了遗传力和遗传相关系数的测定。结果表明，千粒重h2（％）＝83．3，主茎节数h2（％）＝68．9，株高h2（％）＝61．7。千粒重与株粒重r＝－0．12，主茎节数与株粒重r＝－0．236，株高与株粒重r＝0．117。
Six major economic traits of 45 bitter cultivars were tested for heritability and genetic correlation coefficient. The results showed that the weight of one thousand kernels h2 (%) = 83.3, the number of main stem h2 (%) = 68.9 and the height h2 (%) = 61.7. Thousand grain weight and grain weight r = -0.12, main stem number and grain weight r = -0.236, plant height and grain weight r = 0.117.
