| 摘 要： | 广东70％～80％的花生种植在轮作周期较短的瘦瘠旱坡地上，青枯病危害较重，严重威胁花生生产。在调查品种与发病关系中，发现花生抗青枯病力在类型间和品种间有明显差异，因此，应以品种抗病性鉴定和选育作为研究的主攻方向。利用国内外花生品种资源鉴定筛选出抗原材料并通过各种育种途径，选育出高产抗青枯病的花生品种投入生产，减轻青枯病危害，提高花生单产和总产。

| Abstract: | In Guangdong, 70%~80% peanuts were planted in dry-sloping poor fields with short crop rotation cycle. Therefore, peanut bacterial wilt was a serious disease in this area and it became a big threat to local peanut production. To solve the problem, a systematic investigation and deep study of the disease were conducted. A result of the relationship between peanut varieties and bacterial wilt showed that the peanut resistance to this disease is obviously different among varieties and types. Therefore, variety resistance identification and resistant breeding came to the main study point of peanut breeding. On the aspect of peanut resistance breeding, resistance to peanut bacterial wilt was the emphases of peanut breeding before 1970. Rust of peanut becomes major disease gradually after 1969. The goal of peanut breeding was revised in 1972 in Guangdong. Rust resistance with bacterial wilt resistance was became the keystone of the peanut resistance breeding. A series of peanut varieties of high-yield with bacterial wilt-resistance or compatible rust-resistance were applied in peanut planting by the resistant resources screening of domestic and foreign peanut germplasm, breeding technique ways of cross and systematic selection and radioaction variation. With the result that the harm of bacterial wilt of peanut was overcame, the output and production of peanut increased rapidly in Guangdong. It indicated that peanut resources screening and resistance identification laid a solid foundation for breeding of peanut against bacterial wilt. |
