- 摘要:
- 为了促进机收玉米杂交种牡单27高产栽培的推广与应用，本文介绍了牡单27的选育过程、特征特性、产量表现及栽培管理技术要点。牡单27是黑龙江省农业科学院牡丹江分院以玉米自交系My313为母本，以玉米自交系gl288为父本杂交选育而成，适合籽粒机械收获的玉米新品种。2021年参加黑龙江省第一积温带机收组区域试验平均产量10 437.4 kg·hm-2，较对照品种益农玉10号增产2.9%；于2022年参加黑龙江省第一积温带机收组生产试验，平均产量达到13 158.2 kg·hm-2，较对照品种益农玉10号增产7.9%。2023年牡单27通过了黑龙江省农作物品种审定委员会的审定（审定编号：黑审玉20230044）。该品种具有耐密、优质、脱水快等特点，为适宜机械化收获的玉米新品种，在黑龙江省春播生育期为120 d，适宜在黑龙江省第一积温带需≥10 ℃积温2 700 ℃及其他生态条件相近地区种植。
- Abstract:
- In order to promote the extension and application of high-yield cultivation of mechanical harvest maize hybrid Mudan 27, the breeding process, morphological characteristics, yield characters and key cultivation management techniques of Mudan 27 were introduced in this paper. Mudan 27 is a new maize variety suitable for mechanical harvesting, which was bred by Mudanjiang Branch of Heilongjiang Academy of Agricultural Sciences, with maize inbred line My313 as the mother and maize inbred line gl288 as the father. In 2021, the average yield was 10 437.4 kg·ha-1 in the harvest group of the first accumulation temperate zone in Heilongjiang Province, which was 2.9% higher than that of the control variety Yinongyu 10; In 2022, the average yield reached 13 158.2 kg·ha-1 in the production test of the first accumulation temperate zone machinery collection group in Heilongjiang Province, which was 7.9% higher than that of the control variety Yinongyu 10.In the 2023, Mudan 27 was approved by the Heilongjiang Crop Variety Accreditation Committee (accreditation number: Heishenyu 20230044). It is a new maize variety suitable for mechanized harvesting with characteristics of dense resistance, high quality and fast dehydration. It has a growth period of 120 days in spring sowing in Heilongjiang Province, and is suitable for planting in the first accumulative zone of Heilongjiang Province with ≥10 ℃ accumulative temperature of 2 700 ℃ and other areas with similar ecological conditions.
