广东花生抗锈病育种研究进展

Breeding for rust-resistance in peanut in Guangdong

广东花生生产上于1965年首先发生锈病,之后迅速扩展蔓延,严重威胁花生生产。在调查品种与发病关系中,发现花生抗锈力在类型间和品种间有显著差异。选育种植高产抗锈病花生品种是一种经济有效的防治方法。1972年广东省花生育种协作会议把抗锈病育种定为花生育种目标。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,选育出高产抗锈病的花生品种投入生产,减轻锈病危害,提高花生单产和总产。

Rust disease first occurred in peanut in 1965 in Gusngdong. After that, it developed and spread rapidly, threatened peanut planting seriously. A result of the relationship between peanut varieties and peanut rust showed that the peanut resistance to this disease is obviously different among varieties and types. Breeding and planting high - yield with rust - resistance varieties was considered as a radical and economical protecting way among so many prevention ways of the disease. Rust - resistance breeding was determined to the goal of peanut breeding at Guangdong cooperating conference of peanut breeding in 1972. A series of peanut varieties of high - yield with rust - resistance were applied in peanut planting by the resistant resources screening of domestic and foreign peanut germplasm, breeding technique ways. With the result that the harm of peanut rust was overcame, the output and production of peanut increased rapidly in Guangdong.
