早熟高产玉米新品种禾源15是以H05为母本、H06为父本杂交育成的早熟杂交种。2005~2008年进行初级鉴定和品种多点试验示范;2009年预备试验平均产量10 489.5kg/hm2,比相邻对照龙单13平均产量9 505.5kg/hm2增产10.4%;2010年同组区域试验平均产量9 609.0kg/hm2,比对照龙单13平均产量8 872.5kg/hm2增产8.3%;2011年同组区域试验平均产量9 861.0kg/hm2,比对照龙单13平均产量9 063.0kg/hm2增产8.8%;2012年河北省春播极早熟组生产试验平均产量10 225.5kg/hm2,比对照增产12.2%。2013年通过河北省品种审定委员会审定。该品种表现出很好的抗病性、抗逆性、丰产性和稳产性,活秆成熟,品质优良,生育期116~118d,适宜在河北省春播早熟玉米种植区及有效积温≥2 300℃的地区种植。
The new early-maturing and high-yielding maize variety Heyuan 15 is a premature hybrid crossed with H05 as female parent and H06 as male parent. 2005-2008 initial demonstration and varieties of multi-point demonstration; preliminary test in 2009 the average yield of 10 489.5kg / hm2 than the adjacent control Longdan 13 average yield of 9 505.5kg / hm2 yield 10.4%; the same group of 2010 regional test The average output of 9 609.0kg / hm2, compared with the control Longdan 13 average yield of 8 872.5kg / hm2 yield 8.3%; the same group in 2011 the average output of 9 861.0kg / hm2, compared with the control Longdan 13 average yield 9 063.0kg / hm2 An increase of 8.8%. In 2012, the average yield of the spring early sowing group in Hebei Province was 10 225.5kg / hm2, 12.2% more than that of the control. In 2013, it passed the Hebei Province Variety Approval Committee. The variety showed good disease resistance, stress resistance, high yield and stable yield. The live stalk was mature and of good quality with a growth period of 116-118 d. It was suitable for early maturing corn planting area in Hebei Province and effective accumulated temperature ≥2 300 ℃ The area is planted.
