棉花品种（系）抗枯、黄萎病性鉴定表明，在苗床接种棉枯萎病菌粉９０ｇ／ｍ２，３月下旬至４月初播种，覆膜保温，待棉苗１～２片真叶时，采用沾根或伤根灌窝接菌，每苗接黄萎病菌液１０ｍｌ（２×１０７个孢子／ｍｌ），保持床温平均２２～２５℃，鉴定历期１７～２０天，积温４２３．５～４３８．４℃，发病达高峰，鉴定结果田间病床早期鉴定与大田病圃的抗性一致，苗期黄萎病鉴定与花铃期病情指数达极显著相关（ｒ＝０．７２５４～０．９２９５），是棉花抗病育种早期抗性筛选和鉴定的有效方法。
Cotton varieties (lines) resistance to wilt, Verticillium wilt identification showed that in the seedbed inoculated cotton Fusarium powder 90g / m2, 3 months early to early April sowing, film insulation, cotton seedlings to be 1 or 2 true leaves, the use of (2 × 107 spores / ml) of Verticillium dahliae solution per spike, maintaining the average bed temperature of 22 ~ 25 ℃, identifying the duration of 17 to 20 days, the accumulated temperature of 423.5 ~ 438.4 ℃. The results showed that the early identification of field beds was consistent with that of Daejeon nursery. The identification of Verticillium wilt at seedling stage was significantly and significantly correlated with the disease index (r = 0.7254 ~ 0.9295 ) Is an effective method for early resistance screening and identification of cotton disease-resistant breeding.
