摘要:
为促进玉米新品种牡玉307在适宜种植区的推广应用，本文简要介绍了玉米新品种牡玉307的选育过程、特征特性及栽培和制种技术。牡玉307是黑龙江省农业科学院牡丹江分院以自选系绿L118为母本、以自选系绿L1206为父本杂交选育而成的玉米单交种。2021年通过黑龙江省农作物品种审定委员会审定（黑审玉2021L0016）。2017年异地鉴定试验平均产量为11 588.1 kg·hm-2，比对照品种德美亚3号增产6.5%。2018-2019年区域试验平均产量为10 729.3 kg·hm-2，比对照品种德美亚3号增产5.3%。2020年生产试验平均产量为10 788.0 kg·hm-2，比对照品种德美亚3号增产8.5%。综合2018-2020年牡玉307与德美亚3号的产量数据，牡玉307的变异系数为2.46%，德美亚3号的变异系数为2.74%。牡玉307要比德美亚3号产量表现更加稳定，变异范围较小。牡玉307具有耐密、高产、高效、广适、优质、抗性好等特点，适宜在黑龙江省第二积温带≥10 ℃活动积温2 500 ℃区域种植。
Abstract:
In order to promote the application of new maize variety Muyu 307 in suitable planting area,the breeding process,characteristics,main cultivation and seed production technology of new maize variety Muyu 307 were introduced in this paper.The new maize hybrid Muyu 307 was obtained using inbred Lyu L118 as male parent and Lyu L1206 as female parent.It was approved by Heilongjiang Crop Variety Approval Committee in 2021(Heishenyu 2021L0016).In 2017,the average yield of off-site identification test was 11 588.1 kg·ha-1,which was 6.5 % higher than that of the control variety Demeiya 3.The average yield of the regional test from 2018 to 2019 was 10 729.3 kg·ha-1,which was 5.3% higher than that of the control variety Demeiya 3.The average yield of production test in 2020 was 10 788.0 kg·ha-1,which was 8.5% higher than that of the control variety Demeiya 3.Based on the yield data of Muyu 307 and Demeiya 3 from 2018 to 2020,the variation coefficients of Muyu 307 and Demeiya 3 were 2.46% and 2.74%.The yield performance of Muyu 307 was more stable and the variation range was smaller than that of Demeiya.Muyu 307 had the characteristics of density tolerance,high yield,high efficiency,wide adaptability,high quality and good resistance.It is suitable for planting in the second accumulated temperate zone ≥ 10 ℃ and active accumulated temperature of 2 500 ℃ in Heilongjiang Province.
