A Second-Axillary Flower Trait in Upland Cotton1
- J. E. Quisenberry and
- D. R. Rummel2
A cotton (Gossypiura hirsutum L.) strain, “RQSX-I”, was developed which consistently produces flowers at the second-axillary position. The purpose of this investigation was to determine the agronomic value of the trait, to study its production of flowers and fruit, and to estimate its inheritance.
A comparison of RQSXol with two cotton cultivars, ‘Tamcot CAMD-E’ and ‘Lankart 611’, showed that RQSX-l had smaller fruit, earlier maturity, its first fruiting branch at a lower node, more total fruiting positions, fewer fruiting branches, and more fruiting positions/fruiting branch than did either cultivar. It set more fruit than Lankart 611, but not than Tamcot CAMD-E. The inheritance study suggested that the development of the secondaxillary position was under quantitative genetic control.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
