Enhancement of Cotton Boll Retention by GA3 Treatment
Abstract
Cotton quantity and quality improvement could be achieved by
hybridization. Intraspecific and interspecific crossing is one of the ways to transfer desirable gene(s) combinations for crop improve-ment. One of the limitations that face the cotton crossing process is the high flowers and bolls shedding after pollination particularly in interspecific hybridization. During the course of an ongoing program to transfer resistance too bacterial blight from diploids to tetraploids cotton, we experienced excessive boll shedding after pollination. Therefore, the present study was conducted to investigate the effect of GA3 on flower and boll retention after pollination.
