摘要：

为选育野生益智高产品种，筛选选育的主要性状指标，本研究以不同光照条件下7年生野生抚育益智为材料，采用逐步回归，建立产量与各性状的最优线性回归方程。结果表明，不同光照条件下，单株结果数、单果鲜重在相关系数及通径系数等方面均表现出极显著相关，且明显高于其它性状；遮光与光照条件下，各性状与产量间关系存在一定差异。表明单株结果数及单果鲜重为野生抚育益智品种选育主要性状指标。

Abstract:

In order to breed high-yield varieties of wildlife tending Alpinia oxyphyIla,screen main characters of Alpinia oxyphyIla for breeding.In this study,material was 7-years wildlife tending Alpinia oxyphyIla under different light, related path anaylsis and regression equation of yield and main characters of wildlife tending Alpinia oxyphyIla were carried out.Result indicated that fruit numbers pre plant、fresh weight pre fruit and yield of Alpinia oxyphyIla were very significantly correlated in correlated and path coefficient anaylsis,and were more significantly than other characters under different light.But correlative index between all main characters and yield were different under light and covered light.The conclution was that fruit numbers pre plant and fresh weight pre fruit were main characters for screening high-yield varieties of wildlife tending Alpinia oxyphyIla.
