我省晋中和忻定盆地气候温和,适宜高粱生长,种植高粱有明显的优势,是有名的“高粱之乡”。但是,近年来高粱丝黑穗病不断发展蔓延,发病植株颗粒无收,因而种植面积有下降趋势,产量水平停滞不前。由美国新引进的622A高粱不育系,具有高抗丝黑穗病的特点,它农艺性状好,制种产量高,用它配制的杂交种抗4,抗7丰产性能好,好捉苗,较抗蚜虫,是很有前途的新品系。
The Jinzhong and Xinding basins in our province have a mild climate, suitable for the growth of sorghum and have obvious advantages in growing sorghum. It is also famous as the hometown of sorghum. However, in recent years, sorghum smut continues to develop and spread, the incidence of crop particles without income, so the planting area has a downward trend, the output level stagnated. 622A sorghum CMS introduced by the United States has the characteristics of high resistance to head smut. Its agronomic traits are good, the seed yield is high, the hybrids with it are formulated with anti-4 and anti-7 high yielding properties, More resistant to aphids, is a promising new line.
