中文摘要:
      为了选育高产、抗旱、抗倒伏、抗病玉米新品种,山西省农科院现代农业研究中心将传统育种方法与现代育种技术相结合,利用美国优质玉米种质资源PH6WC和PH4CV,通过杂交和二环系选育,对本研究室历年来选育的优良自交系进行了改良,并通过分子辅助抗性鉴定等方法,筛选获得T0725和T0750优良自交系,通过测配、品比试验、不同生态区布点试验以及生产试验,获得适应性广、综合农艺性状优良、产量高的玉米新品种‘盛玉68’,较对照平均增产5%以上,且中抗大斑病,中抗穗腐病,中抗粗缩病。并于2016年通过山西省品种审定委员会审定。‘盛玉68’具有高产、优质、多抗、耐密等优点,容重735 g/L,粗蛋白含量10.00%,粗脂肪含量3.72%,粗淀粉含量72.56%,属高淀粉品种,出籽率87.1%,平均产量达11841 kg/hm2。该品种的种子生产技术简便,产量高,降低了生产成本。在生产中结合科学管理,提高单产,带动总产增加,为保障粮食安全奠定基础,具有广阔的开发应用前景。
英文摘要:
      To obtain new maize varieties with high yield, drought resistance, lodging resistance and disease resistance, Research Center of Modern Agriculture of Shanxi Academy of Agricultural Sciences combined traditional breeding methods and modern biotechnology to make full use of high-quality American germplasm resources, aiming to improve excellent inbred lines bred by the center. T0725 and T0750 inbred lines were obtained through hybridization and second cycle breeding, associated with molecular assisted resistance identification methods. Then test-cross, variety comparison test and production test in different ecological test sites were conducted to obtain the new maize variety‘Sheng Yu688’which had characters of wide adaptability, good agronomic characters and high yield, and the yield increased by 5% and above compared with that of CK, and had moderate resistance to blight, ear rot and rough dwarf disease. The variety was approved by Shanxi Variety Approval Committee in 2016.‘Sheng Yu688’has high yield, high quality, multi resistance and dense-resistance, with features as follows: the bulk density of 735 g/L, crude protein content of 10%, crude fat content of 3.72%, crude starch content of 72.56%, which indicated that it was a high starch variety; its seed rate is 87.1%, the average yield reaches 11841 kg/hm2. The seed production technology of the variety is simple and convenient, with high yield and reduced production cost.
