谷子光敏型显性核不育材料“光A_1”选育研究初报

A Preliminaty Observation on Breeding of Photoperiod-sensitive and Dominant GMS Material of Foxtail Millet "Guang A_1

1987年在显性核不育材料“宁黄A”中获得一雄性不育材料,表现在长日照(14.5小时/日)条件下雄性不育,在短日照(11.2小时/日)条件下雄性可育.关于谷子光敏型显性核不育材料,国内外尚未见报道,它的发现为谷子显性核不育材料的利用开辟了新途径,在理论研究及杂种优势利用方面都颇有价值.

A male sterile experimental material was obtained from Ninghuang A-the dominant genie male-sterile material in 1987. The male part of the new material cannot reproduce under condition of long sunshine (about 14.5 h/d), whereas it can do, if the sunshine is short (about 11.2 h/d). The photoperiod-sensitive and dominant genie male-sterile material of millet has not been reported both at home and abroad. Discovery of this material will open a new way of utilizing the dominant genie male-sterile material of millet.
