新玉35号是新疆农科院粮作所育出的早熟优质高产粮饲兼用高淀粉玉米新品种,2006年2月通过新疆农作物品种审定委员会审定。该品种在新疆北疆春播产量684.6~850 kg/667 m2,最高产量996.8 kg/667m2,生育期105 d。南疆复播产量582.9 kg/667 m2,比对照新玉9号增产9.3%,复播最高产量734.3 kg/667 m2,比对照增产15%,生育期89 d,与对照相当,所需≥10℃有效积温2 300℃。籽粒粗蛋白含量10.4%,达到国家饲料玉米一级标准,粗脂肪4.8%,赖氨酸含量0.32%,淀粉含量74.73%,达到国家高淀粉玉米二级标准。籽粒容重764 g/L,千粒重300 g,籽粒硬粒,金黄色。植株高达280 cm,生物产量高,保绿性好,可粮饲兼用,亦可加工淀粉,适合新疆南疆复播和北疆冷凉地区春播种植。 Xinyu 35 is a new breed of high starch corn with early maturity, good quality and high yield, which was bred by Xinjiang Academy of Agricultural Sciences. In February 2006, it was approved by Xinjiang Crop Variety Approval Committee. The yield of this variety was 684.6 ~ 850 kg / 667 m2 in spring in northern Xinjiang, the highest yield was 996.8 kg / 667m2 and the growth period was 105 d. The yield of re-broadcast in southern Xinjiang was 582.9 kg / 667 m2, which was 9.3% higher than that of Xinyu 9 and the highest yield of replanting was 734.3 kg / 667 m2, 15% more than the control and 89 d of growth, which was equivalent to the control ℃ effective temperature 2 300 ℃. Crude protein content of 10.4%, reached the national standard for a first-grade feed corn, crude fat 4.8%, 0.32% lysine content, starch content of 74.73%, reached the national secondary standard of high starch corn. Grain weight 764 g / L, 1000 grain weight 300 g, grain durum, golden yellow. Plant up to 280 cm, high biological yield, good green, can feed and feed, starch can also be processed, suitable for sowing in southern Xinjiang and northern Xinjiang cool sowing spring planting.
