Abstract
This article reports the research results of the photoperiod inducement flowering of shy-flowering sugarcane parents in Sugarcane Research Institute, Yunnan in 1999. The experiments used 9 shy flowering parents as entry, started on April 1 and June 1 respectively, with two kinds of daylight duration treatments of 12 h 25 min and 12 h 15 min. From October 1, both daylight treatments were reduced by 30 s every day until tassel. The results showed that two varieties had been induced flowering for the first time, which were noble cane Crystalina and Yue Nan Niu Zhe, two varieties had been induced pregnant for the first time, which were noble cane Badila and 48Mouna, at Kaiyun of high latitude and high sea level. Besides, three varieties had been induced flowering in both years, which were Yuetang 57/423、Co419 and Mintang 70/611. Morever their first heading dates were earlier than usual, average earing rate had been raised. This article suggests that temperature be possible main factor affecting shy flowering parents flowering under condition of the same photoperiod treatment.
