1978～1979年在广州郊区进行水稻抗稻瘿蚊品种筛选鉴定,经多次重复鉴定,国外引进的品种中,无标葱的有W_(1263)、R_(7-2757)、R_(35-2750)、RD_9、BKNBR_(1030-76-2)、ARC_(6650)等13个;标葱率1～5%的有R_(35-2739)、IET_(6013)、BG_(404-1)等12个;标葱率在15%以下的有CR_(180-4)等12个。初步鉴定本国品种资源,无标葱的有鸡咀占,标葱率在5%以下的有大科占、晚金风6号等17个。鉴定方法先行苗期初筛和复筛,将标葱率15%以下的在本田期再行重复鉴定,这样能比较准确、快速地进行筛选鉴定,以明确其抗性,找到抗源。
From 1978 to 1979, screening and identification of rice resistant to rice gall midge in Guangzhou suburb were carried out. After repeated identification, among the introduced varieties, W_ (1263), R_ (7-2757), R_ (35- 2735), RD_9, BKNBR_ (1030-76-2) and ARC_ (6650), etc .; R_ (35-2739), IET_ (6013), BG_ (404-1) 12; standard rate of 15% of the following CR_ (180-4) and other 12. Initial identification of its own variety of resources, no standard onions with chicken Tsui, the standard rate of 5% under the large branches accounted for late Goldenwind on the 6th and so on. Identification method First seedling early screening and re-screening, the standard scallion rate of less than 15% in the Honda re-repeated identification, it can be more accurate and rapid screening identification to identify their resistance to find the source of resistance.
