Abstract:

(Aim)To study the correlation between several economical properties and tuber yield of pinellia ternata，and compare the impact degrees of these economical properties to tuber yield．The study will offer reference for pinellia ternata selection；(Methods)Plant pinellia ternata from different sources into the common garden，and record the number of 3 type tubers，the weight of hundred tubers，the yield of tuber in unit area，and analyze the correlation coefficient，path coefficient；(Result)The tuber yield correlated significantly with big tuber ratio and hundred tuber weight，slightly negative with small tuber ratio；（Conclusion）The significance of these economical properties to tuber yield is hundred tuber weight＞small tuber ratio＞middle tuber ratio＞big tuber ratio in turn．Accordingly，the yield of tuber will be increased significantly if we increase the big tuber ratio and the hundred tuber weight，reduce the small tuber ratio，and control the middle tuber ratio．
