一、爱字棉品种1975年在圣华金河谷的黄萎病及缺钾地区已宣布以爱字棉SJ-4替换SJ-3。SJ-4在黄萎病地的平均皮棉产量为每英亩1038磅(合每亩约157斤),在无病地上则为1065磅(约161斤)。纤维长度2.5%跨长为1.13吋,气流测定纤维细度值为4.09,强度指数为2.44T,衣分率为32.3%。SJ-4的农艺特性是:对黄萎病和缺钾有高度耐性,纤维强度大,纱线强力高,种子榨油的特性也比以前各品种为优。二、安德逊克来敦种子公司的品种1.佩马斯特266 丰产、早熟、抗风暴,对黄萎病的抗性优于高原其它品种。在这几
First, the word cotton varieties In 1975 in the San Joaquin Valley, Verticillium wilt and potassium-deficient areas have been announced to replace SJ-4 Sword cotton SJ-4. The average lint yield of SJ-4 in Verticillium wilt was 1038 pounds per acre (about 157 pounds per acre) and 1065 pounds (about 161 pounds) in disease-free land. The length of 2.5% of the fiber length was 1.13 inches, the fineness value of the air flow was 4.09, the strength index was 2.44T and the percentage of clothing was 32.3%. SJ-4’s agronomic characteristics are: highly resistant to Verticillium wilt and potassium deficiency, fiber strength, high yarn strength, seed oil extraction characteristics than the previous varieties are excellent. Second, the Andean Keliday seed company varieties 1. Mamasteer 266 high yield, precocious, anti-storm, the resistance to Verticillium wilt is better than other varieties in the plateau. In these few
