摘要：

为适应当前玉米密植与机械化快速发展的需求,利用国外优异玉米种质材料组配基础群体,采用高密度大群体,定向接种鉴定等方法,以选育的抗病优良自交系‘RP86’为母本,‘RP06’作父本,杂交组配育成耐密抗逆高产宜机收玉米新品种‘瑞普909’。区试平均产量为12589.5 kg/hm 2,比对照品种增产7.1%,试验点111个,增产点占93%;生产试验产量为12601.5 kg/hm 2,比对照品种增产7.7%,试验点54个,增产点占95%。区域和生产试验平均倒伏（倒折）率1.6%,抗大斑病、茎腐病和穗腐病。籽粒粗淀粉含量75.24%。研究表明,该品种高产稳产、抗病抗倒、品质优良、适应性广、耐密植、宜机收。2017年通过山西省审定,2018年通过陕西、内蒙古和国家审定。适宜在东华北、西北春播中晚熟区和山西南部等黄淮海夏玉米区推广种植。

Abstract:

To adapt to dense planting of maize and meet the rapid mechanization development of agricultural production, the basic maize population was developed by using abroad excellent germplasm materials, then high-density and large-population selection, targeted inoculation and identification methods were adopted to obtain the new variety ‘Ruipu909’ with the disease-resistant self-line ‘RP86’ as female parent and ‘RP06’ as male parent. This variety has characteristics of density resistance, stress resistance, high yield and easy mechanical harvesting. The results show that the average yield of the regional test is 12589.5 kg/hm 2, 7.1% higher than that of the control variety. There are 111 test points, the yield-increase points accounted for 93%. The yield of production test is 12601.5 kg/hm 2, compared with the control variety, the yield increased by 7.7%, and there are 95% yield-increase points among the 54 test points. The average lodging rate in regional and production tests is 1.6%. ‘Ruipu909’ is resistant to northern corn leaf blight, stalk rot and ear rot. The crude starch content of seeds is 75.24%. In summary, the new variety ‘Ruipu909’ has multiple characteristics of high and stable yield, strong disease and lodging resistance, good quality, wide adaptability, density resistance and is suitable for mechanical harvesting. The variety was examined and approved by Shanxi Province in 2017 and was further approved by Shaanxi, Inner Mongolia and passed the national authorization in 2018. The variety is suitable for popularizing and planting in middle-late maturing areas of spring sowing regions in eastern north China and northwest China and Huanghuaihai summer maize areas in southern Shanxi.

Key words: maize variety, ‘Ruipu909’, density resistance, stress resistance, high yield, mechanical harvesting, selection and breeding
