1997～ 2 0 0 0年 ,在 638份陆 (旱 )稻资源的抗瘟性鉴定基础上 ,优选出 5 8份陆 (旱 )稻品种 (系 )。分别以Moroberkan与B40为抗、感对照品种 ,在湖南省稻瘟病鉴定中心安化烟溪 ,采用稻瘟病旱病圃与自然诱发 ,以旱种旱管与雨育的栽培方式进行旱病圃持久抗瘟性鉴定及多抗性研究。筛选出一批可作为多抗性育种目标的亲本和成熟期适宜、适合我省天水田和坡土种植的大白谷 (粳陆 )、魔王谷 (粳陆 )、86-87(籼陆 ) 3个持久多抗 (病、虫 )优质的旱稻品种。
From 1997 to 2000, based on the identification of blast resistance of 638 land-sourced drought and drought-tolerant rice varieties, 58 varieties of land and drought-tolerant rice were selected. Respectively Moroberkan and B40 resistance, the sense of control varieties, in Hunan Province Rice blast Identification Center Anhua Yanxi, using rice blast disease nursery and naturally induced drought-rain and rain-fed cultivation of drought nursery long-lasting Identification of blast resistance and multiresistance study. A batch of parents that can be used as breeding targets for multiresistant breeding and suitable maturity stage were selected, which were suitable for the planting of Da Bai Gu (Japonica), Devil Valley (Japonica), 86-87 (Indica) of Tianshui and slope soil in our province A durable multi-resistant (disease, insect) high-quality upland rice varieties.
