美国农业部等单位于1981年7、8月份先后发放了12个抗锈病的花生种质: 蒂夫顿抗锈1号(GP18)——晚熟,生育期145—155,叶片中等绿色,花瓣色深。平均单粒重0.5克。此种质在佐治亚州蒂夫顿地区对由Cercospora arachidi-cola所引起的叶斑病,在印度国际半干旱热带作物研究所对由Cercospora Spr-idium personatum所引起的叶斑病均表现有明显抗性。 蒂夫顿抗锈2号(GP19)——生育期140天左右,叶片淡绿色,花橙色。小粒,单粒重约0.4克。据印度国际半干旱作物所观察,对C·Personatum叶斑病具有一定抗性。
The United States Department of Agriculture and other agencies issued 12 rust resistant peanut germplasms in July and August of 1981 successively: Tifton rust No.1 (GP18) - late maturing, growth period 145-155, leaf medium green, deep. The average weight of 0.5 grams. This species of leaf spot caused by Cercospora arachidi-cola in Tifton, Georgia, showed significant resistance to leaf spot caused by Cercospora spr-idium personatum at the Indian International Crop Research Institute for Semi-Arid Tropics Sex. Tifton rust 2 (GP19) - about 140 days of growth period, the leaves light green, orange flowers. Small particles, single grain weighs about 0.4 grams.
