The new sterile line M_A bred with the maintainer line still has the character of recessive nuclear sterility and both G. hirsutum and G. barbadense varieties are its restorers.
With 6 different genetic background and high pure upland cotton lines as female parents, the variation of allogamous affinity and main traits of hybrid boll were analyzed under assisted pollination.
The correlation among main yield and fiber traits of upland cotton with high fiber quality was investigated by using correlation and path analysis methods.
Studies on the inheritance of resistance to Verticillium wilt of upland cotton, and the identification of differently expressed genes about the interactions between upland cotton and V. dahliae Kleb.
By using techniques of X-ray diffraction, effects of anthesis date on the dynamic change of cotton fiber super-molecular structure and strength were studied.
Most glandless varieties, which are easy to produce hybridization naturally in the field, and cause unsafe to eat, are due to recessive glandless genes.
The similarity coefficients between wild species and its filial lines were 0.388~0.479, those similarity between upland cotton and germplasm lines were 0.636~0.892, vice verse.
