扬麦158由江苏里下河地区农科所在扬麦4号×st1472/506选系的基础上,采用综合育种方法育成.我市于1988年引进,1990年秋播起对其生育特性、产量形成规律及高产栽培技术进行了试验研究.一、产量表现据我市3年品比和生产示范,该品种亩产352～421.gkg,平均390kg,比扬麦5号增产13.4%,达极显著水平.1992年我市超稀播繁殖(亩播量3～3.5kg)450亩,平均亩产377kg.其中洋溪乡徐(?)村135.6亩连片示范方,平均亩产402.1kg,比扬麦5号增产14.9%.该村农户邵坤法种植的2亩,实收亩产达480.8kg,均创我市小麦生产的新纪录.
Yangmai 158 was bred by a comprehensive breeding method based on the selection of Yangmai 4 × st1472 / 506 line in the Lixiahe area of Jiangsu Province. The city was introduced in 1988 and sown in the autumn of 1990 with its fertility characteristics and yield formation Law and high-yielding cultivation techniques were studied.First, the yield performance According to the city’s three-year product ratio and production demonstration, the varieties per mu 352 ~ 421.gkg, an average of 390kg, 13.4% increase than the Yangmai 5, reaching a significant Level .In 1992, the city of ultra-thin sowing propagation (mu sowing 3 ~ 3.5kg) 450 acres, the average yield of 377kg .Yangxi Township Xu (?) Village 135.6 acres of contiguous demonstration, the average yield per mu 402.1kg, Yangmai 5 increased by 14.9% .The village farmers Shao Kun method planted 2 acres, the real yield of 480.8kg per mu, are creating a new record of the city’s wheat production.
