Liaoning cultivated new varieties of cotton with special early-maturity, high-yield and stable disease resistance

Early maturation, high yield, and early maturation are not diseases. This is a headache for cotton breeding. The Economic Crops Research Institute of Liaoning Province, which lasted for nine years, worked hard to develop a new cotton variety named “Liaomian 19,” which was a combination of many kinds of good quality. It filled the gaps in China's cotton varieties that are both extremely early and resistant to pests with high yields and stable yields.
The “Liao cotton No.19” in the summer of the Yellow River Basin cotton-growing area of ​​105 days 108 days, than the introduction of foreign insect-resistant cotton 33B early opening 6-8 days, the pre-frost flower rate as high as 955 or more, belong to the special premature Variety. The results of disease resistance identification in the artificial sickbed indicated that both the fusarium wilt and verticillium wilt, which are known as cotton cancers, have reached high levels of resistance. The field and indoor insect resistance identification results showed that the bollworm had a stronger resistance to insects than the introduced variety 33B. The results of a number of multi-point trials since 2000 show that "Liaomian 19" has high yield and stable yield, with an average yield of 86.7 kg of lint per mu. The five agricultural divisions of the Xinjiang Production and Construction Corps also created an astonishing record of an average of 120 kilograms of lint per mu and 160 kilograms of lint per mu.
