谷子耐旱、耐瘠薄,是主要的粮食和饲草作物之一。承德地区历年谷子播种面积一般为100—140万亩,最高曾达192.3万亩。但由于缺少高产质优,抗逆性强、粮草兼用的优良品种,加上种植粗放,病虫害严重,致使生产水平较低,亩产仅300斤左右。为适应谷子生产发展需要,我们以高产(超冀谷3号10%以上)抗灾(耐旱、耐瘠)适应性强(山平地均可种植)生育期相当于冀谷3号,粮草兼用为育种目标。经过杂交选育,已选出基本符
Millet drought, barren, is one of the major food and forage crops. Chengde area calendar year millet sown area is generally 100-140 acres, the highest reached 1,923,000 mu. However, due to the lack of high yield and good quality, strong resistance, forage and fine varieties, coupled with extensive planting, pests and diseases seriously, resulting in lower production levels, only about 300 kg per mu. In order to meet the needs of the development of millet production, we have a high adaptability (drought-tolerant and barren-tolerant) with high yield (more than 10% of Chaoji 3) Breeding goals. After crossing breeding, has selected the basic character
