Method for producing cotton seeds by inducing long cotton stigmas
A technology of long stigma and cotton, which is applied in the production of hybrid cotton hybrid seeds and cotton artificial long stigma seed production. It can solve the problems that the purity of hybrids cannot meet the production requirements and the difference between flowers is large, so as to improve the efficiency of seed production and breeding. The effect of short cycle and strong adaptability

[0019] 1.1 Species tested: Sumian 22, American Jijiaoye.
[0020] 1.2 Test location: Lishui Plant Science Base of Jiangsu Academy of Agricultural Sciences.
[0021] 1.3 Test treatment:
[0022] The experiment was carried out between 2008 and 2010. In 2008, the suitable induction concentration and induction method of GA3 solution, the research and development of small-scale pollinators and heat-insulated pollinators were mainly carried out. In 2009, on the basis of the previous year's work, completed the technical research on pollination with conical turbine negative pressure pollinators; on the basis of heat-insulated pollinators, began to develop low-temperature energy-storage cotton pollinators; In terms of the technique of inducing long stigmas, we have carried out a study on the actual effect of stably inducing more than 95% of the stigmas higher than the stamen clusters by more than 8mm for cotton hybrid seed production. In Sumian 22, ...
