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.
