【目的】选育适宜新疆种植的中熟高淀粉玉米品种。【方法】选择中熟玉米自交系502作母本,588作父本,进行品种试验、区域试验和生产试验。【结果】新玉41号区试产量907.15 kg/667 m2,比对照新玉13增产8.86%,生产试验产量860.6 kg/667 m2,比对照增产10.38%,增产达极显著水平。生育期126.6 d,比对照晚熟2.9 d,所需≥10℃有效积温2 600℃。耐旱指数1.39,超过1级耐旱水平,具有极强的耐旱性。籽粒容重730g/L,淀粉含量75.96%,千粒重330 g,籽粒半马齿,金黄色。抗玉米黑粉病、丝黑穗病和青枯病。适宜种植密度为4 500~5 000株/667 m2。【结论】新玉41号中熟耐旱高产高淀粉粮饲兼用玉米新品种,2007年2月通过新疆农作物品种审定委员会审定(审定号:新审玉2007年31号)。2008年9月申请国家植物新品种权(20080475.8)。适宜新疆北疆地区春播、南疆地区套播种植。
【Objective】 Breeding middle-aged and high-starch corn varieties suitable for planting in Xinjiang. 【Method】 The middle-aged maize inbred line 502 was selected as the female parent and the male parent 588 as the male parent. The varieties, regional experiments and production experiments were conducted. 【Result】 The test yield of Xinyu 41 was 907.15 kg / 667 m2, which was 8.86% higher than that of Xinxu13. The yield of trial production was 860.6 kg / 667 m2, 10.38% higher than that of the control, with a significant increase in yield. The growth period was 126.6 days, 2.9 days later than the control. The effective accumulated temperature of ≥10 ℃ was 2600 ℃. Drought index 1.39, more than a drought level, with strong drought tolerance. Grain weight of 730g / L, starch content of 75.96%, 1000 grain weight 330 g, grain half-dentate, golden yellow. Resistance to corn powdery mildew, head smut and bacterial wilt. Suitable planting density of 4 500 to 5 000 plants / 667 m2. 【Conclusion】 New Jade 41, a medium-maturity, drought-tolerant and high-yielding high-starch food and maize new variety, was approved by Xinjiang Crop Variety Approval Committee in February 2007 (Validation No .: Shin-jian jade 2007 No.31). September 2008 for the National Plant Variety Rights (20080475.8). Suitable for spring sowing in northern Xinjiang, sowing in southern Xinjiang planting.
