摘　　要：衡谷12号是河北省农林科学院旱作农业研究所培育的矮秆、极早熟、分蘖性强的谷子新品种。2019年从衡谷12号繁种田获得高矮异株突变体,对该材料进行两年一点、一年两点和错期播种,为鉴定该突变体的稳定性以及深入研究株高、分蘖、抽穗期提供可靠试验材料。结果表明,衡谷12号高矮异株突变体具有稳定遗传特性,农艺性状表型不受时间、地点、播种期的影响,可作为稳定遗传材料使用。Henggu 12 is a new millet variety with low stalk,extremely early maturity and strong tillering ability,which was developed by the Institute of Dry Farming Agriculture of Hebei Academy of Agriculture and Forestry Sciences.In 2019,the hetero-short and tall mutant was obtained from Henggu 12 breeding field.In order to identify the stability of the mutant and provide reliable test materials for further study of plant height,tillering and heading stage,the material was sown at one point in two years,two points in one year and at the cutoff stage.The results showed that the hetero-tall and short mutant of Henggu 12 had stable genetic characteristics,and the agronomic traits and phenotypes were not affected by time,location or sowing date,so it could be used as stable genetic material.
