Abstract
An excellent hybrid cotton cultivar with glyphosate resistance trait, Zheza 14, was obtained by the testing and screening widely for the crosses a somatic glyphosate resistance mutant (R1098) with other upland cotton cultivars or lines. Six different resource hybrid seeds of Zheza 14, from Henan, Anhui and Zhejiang Provinces, were tested for the seed purity, using the method of seed germination and seedling identification with the 30 mL·L -1 glyphosate solution. As the results of seedling identification, the purity of hybrid seeds from Henan Province was the best, with the purity rate of 91.7%~92.4%, next was that from Zhejiang Province with a seed purity of 85.6%~86.6%, and that from Anhui Province was the worst and the seed purity rate was only 77.7%~ 81.9%, although the parent seeds were the same. The results of the seed purity judgment tested by the seed germination method were slightly lower than that of seedling identification, but the tendency of both results was extremely alike, which illustrated that the seed germination test method could be used as the fast judgment for the hybrid seed purity. The field experiment for the different purity rate of the hybrid seeds shown that there was a significant correlation between the seed purity and the lint cotton yield, the glyphosate treatment could increase the seed purification and its yield, as well as the fiber quality, especially for the staple length, fiber uniformity and fiber strength. In addition, the results shown that the seed purity rate for the upland cotton hybrid should be higher than 90%, otherwise the lint cotton yield and fiber quality will be affected greatly.
