Genetic Tendency of Ornamental Characters in Reciprocal Crosses Generation Between Phalaenopsis ‘Frigdaas Oxford’ and Phal.SH49 Cultivars
摘要
Abstract
Phalaenopsis ‘Frigdaas Oxford',Phd.SH49 cultivars and the F1 offspring of reciprocal crossing were used to analyze the genetic tendency of the ornamental characters,such as flower color,flower pattern,flower texture,plant size and flower size,etc.The results showed as follow that the separation tendency was basically the same in both the cross and reciprocal cross generation.The F1 offspring were divided into 4 groups (G01-G04) based on the flower characteristics.The mean values of the 9 quantitative characters in the F1 offspring were significantly lower than the midparent value,which were suitable for the breeding of small plant size or small flower type offspring.The qualitative characters of the F1 offspring showed various separation on flower ground color,flower pattern and flower texture,etc.The heritability and the coverage degree differed in different color,that the darker color pattern could cover the lighter ground color,and furthermore there were new color pattern appears.These characteristics separation and genetic tendency could support in selecting new individuals or new cultivars in the future,and this research could supply directed breeding reference for certain floral traits.关键词
