In 1979, Henan Province Xinxiang Qili Camp Commune test station disease-resistant varieties of regional trials, 183.6 kg of mu per lint, the highest yield, 86.1 than the control variety yield 12.9%. In 1980, six units in Xinxiang were tested with an average of 236.6 kg of lint per mu, an increase of 9.8% over that of the control 86-1. In 1981, he took part in the regional testing of disease-resistant varieties in the province. Among the 5 units, 4 ranked the first with an average incidence rate of 2.4% and a disease index of 1.5%, an increase of 10.9% over that of the resistant variety 5245.
