谷子是短日照作物,对光照反映敏感,所以品种区域适应较小。通过异地不同纬度、海拔鉴定,了解谷子生长发育的特点和性状变化,可为南育加代进行选择和筛选对光照反映较不敏感、适应性较广的材料提供依据。试验以陕西关中夏谷农家品种为材料,分早熟(80—90天)、中熟(91—99天)、晚熟(100天以上)三个组别,还种了吉林公谷6号和山西长农1号,均在广东陵水县相同条件下一次播种,未设重复。
Millet is a short-day crop, sensitive to light reflection, so the breed to adapt to smaller regions. Through the identification of different latitudes and altitudes in different places to understand the characteristics of millet growth and development and the changes of traits, it can provide the basis for the selection and screening of South Yuadai for the materials that are less sensitive to light and more adaptable. The experiment was conducted in the three groups of farmland breeds of Guanzhong Summer Valley in Shaanxi Province, including early maturing (80-90 days), medium maturing (91-99 days), late maturing (over 100 days), and planting Jilin Gonggu No.6 and Shanxi Changnong 1, all sown under the same conditions in Lingshui County, Guangdong Province, was not duplicated.
