1984～1986年,把全国棉花抗病攻关品种(系)及有关单位的抗枯萎病育种材料109个,分为两份。一份种植在供种单位的病圃,调查苗、蕾期枯萎病发病株率及病情指数,另一份做室内棉种浸提液对晃血球的凝集力测定。试验结果,田间病情指数低的材料,棉种浸提液对晃血球的凝集力强,表现抗枯萎病能力也强,反之,田间病情指数高的材料,室内棉种浸提液对晃血球的凝集力则差,棉株抗枯萎病能力亦弱,田间和室内测定结果,两者基本一致,相关性测定达到极显著水准。
From 1984 to 1986, the national cotton disease resistance varieties (lines) and the relevant units of resistance to blight breeding material 109, divided into two. A planted in the nursery for the units, the investigation of seedlings, the incidence of blight bud stage and the disease index, the other to do indoor cotton seed extract on the scoliosis agglutination determination. The results showed that the materials with low disease index in the field and the leaching solution of cotton seed had strong ability of agglutination on sciatic blood cells and strong ability of resistance to blight. On the contrary, the material with high disease index, The cohesive force is poor, the ability of cotton plants to resist fusarium wilt is also weak, and the results of field and indoor tests are basically the same, and the correlation determination reaches a very significant level.
