| 摘 要： | 利用PI312777抗草稻种材料,与本单位优质稻核心种质及其衍生系统材料广泛杂交配组,创建一批以PI312777衍生系统为主的新型育种材料。建立水稻抗草育种圃,重点针对抗草特性和综合农艺性状,通过田间抑草效应筛选,培育水稻抗草苗头株系,在稳定世代(F4代以上)应用以水稻特征次生物质为标记评价水稻品种(系)化感潜力的方法,辅助选育水稻抗草新品种(系)。初步提出适合华南稻区的以田间筛选和评价为主,以特征次生物质标记评价水稻品种(系)化感潜力的方法为辅,田间与实验室相结合,操作性强、简便有效的水稻抗草育种方法。

| Abstract: | A set of new breeding materials derived from PI312777 were established by using PI312777 rice accessions as weed-suppressing parents,and a rice breeding nursery was founded.Weed-suppressing rice plants were selected by evaluating their weed-suppressing effects and focusing on their agronomic characters in the field,and new varieties (or lines) of weed-suppressing rice were developed by evaluating the allelopathic potential of rice plants with applying specific secondary metabolite markers at late generations (after F4).A rice breeding method for weed-suppressing in South China,in which,main evaluation in the field and assistant evaluation by applying secondary metabolite markers,was mentioned. |
