Analysis on Breeding Values of Sugarcane with Consanguinity of E. arundinaceus and Their Crosses
摘要
Abstract
In this paper, the Australian family test method was used to evaluate the genetic characteristics of sugarcane with consanguinity of E. arundinaceus and the effect of crosses selection. The plant height, stalk diameter, millable stalks, cane yield and brix in 25 F1 groups were studied by R sofeware, the analysis of genetic variation, genetic variance and economic breeding value ( EBV) was conducted. The results suggested that plant height, stalk diameter and brix were determined by the additive gene effect of female parents and non-additive gene effect, and cane yield and millable stalks were determined by the additive gene effect of female parents. The EBVs of 10 female parents were from -1724.3 RMB to 908.78 RMB, and 5 of them were above zero. The EBVs of 9 male parents were from -167.33 RMB to 243, 86 RMB, and 4 of them were above zero. The EBVs of 25 families were from -1749.43 RMB to 1474.77 RMB, and 14 of them were above zero. Among the 10 female parents, Yacheng 11-31, Yacheng 07-71, Yacheng 06-140 were recommended to be used in commercial crossing. Among the 9 male parents, Yacheng 05-164 and Yacheng 07-20 were recommended to be used in commercial crossing. Among the 25 families, the cross combinations Guitang 02-761 × Yacheng 05-164, Dezhe 93-88 × Yacheng 06-61, Yacheng 11-31 × ROC22, Yacheng 07-71 × HoCP 02-623 and Yacheng 12-8 × K86-110 could be used widely in sugarcane breeding.关键词
