Abstract:

In order to screen healthy and excellent introduced sugarcane germplasm, enrich sugarcane hybrid parent resources and obtain excellent sugarcane varieties with direct popularization and application value, 41 foreign sugarcane germplasm materials from France, United States, Barbados, Belize, Jamaica, Romania, Guyana and other countries introduced through Visacane, CIRAD, France, responsible for introduction, export and quarantine of sugarcane germplasm from different countries, were planted in quarantine house for two sugarcane growth cycles. During the period, the quarantine disease such as sugarcane white stripe disease, Fiji disease and gummosis disease were monitored. After qualified quarantine, the natural disease occurrence, agronomic traits, cane yield and sugar content were investigated in field experiment. The 41 introduced foreign sugarcane germplasm entries had quarantine diseases and pests. In the field natural disease test, there were nine sugarcane germplasms B03-224, B03-876, FG08-057, FG08-757, FG09-128, FG09-331, FG09-367, FG09-538 and FR89-746 with good disease resistance, which could be used as disease resistant parents. Eight high sugar germplasms with high sugar content, B03-224, BBZ88-343, BJ99-32, BR08-004, CP04-1844, CP05-1526, FG06-691 and FG09-367, were evaluated as 1 grade, which could be used as high sugar parent. Five high-yield germplasms with high yield, BZ93-855, CP00-1446, FG09-124, FG09-346 and FR90-881, were evaluated as grade 1 and could be used as high-yield parents. Eleven germplasms, B03-224, BBZ93-855, BJ99-106, CP00-1446, CP05-1526, FG04-333, FG06-691, FG07-338, FG09-124, FG09-128 and FG09-367, with high-yield and excellent agronomic characters, entered the next round of comparative test to continue screening. In order to select sugarcane germplasms with high yield, high sugar and disease resistance that can adapt to the ecological environment of Guangxi for direct planting, four with excellent comprehensive performance, B03-224, FG09-128, FG09-367 and CP05-1526, were selected for the further variety comparison test. All sugarcane germplasms were kept in Nanning Sugarcane Germplasm Resources Nursery and Sanya Sugarcane Cross Breeding Base of Guangxi Academy of Agricultural Sciences for further evaluation of drought resistance, cold resistance, and subsequent cross utilization. This study could provide reference for the utilization of sugarcane germplasms introduced from abroad.
