超早熟、矮秆谷子品种衡谷12号的选育及其早熟性研究
The Study on the Breeding and Prematurity of a Ultra-Early Maturing and Dwarf Foxtail Millet Variety Henggu 12
摘要
Abstract
In order to solve the problem of the shortage of early maturity and widly ecological adaptability foxtail millet varieties for disaster relief and prevention,a new ultra early-maturing foxtail millet variety Henggu 12 was selected using the early maturing variant of Henggu 9 by a single-plant breeding method for eight consecutive years and the photo-thermal adaptability of its ultra-early maturity was studied.The results showed that the average time from emergence to heading of Henggu 12 is 25 days,and the shortening of vegetative growth period became the major factor leading to its ultra-early maturity.Henggu 12 has 58 days growth period,and the latest sowing date is mid-August in the summer foxtail millet region.It could mature normally in the area between 37°53′N and 50°15′N,and the early-maturity performance was stable.The analysis of meteorological conditions showed that normal maturity of Henggu 12 required the active accumulated temperature≥1215℃and the average sunshine hours≥362 h.关键词
