- 摘要:
- 为促进玉米单交种边单10号的推广应用，本文简要介绍了边单10号的选育过程、特征特性、产量表现、栽培技术及适应种植区域。边单10号玉米品种是黑龙江省农业科学院黑河分院以沈阳农科院引进自交系辽自3370为母本和自育自交系FL236为父本杂交育成。于2021年6月通过黑龙江省审定，审定编号：黑审玉202110014。该品种为普通玉米品种，种子出土能力强，幼苗长势好。茎秆韧性好，根系发达，具有较好的抗倒性、抗旱性，较抗玉米丝黑穗病、大斑病、茎腐病。2018-2019年两年区试平均产量9 963.6 kg·hm-2，2020年生产试验产量8 447.0 kg·hm-2，且品质优良。在适应区出苗至成熟生育日数为110 d左右，需≥10 ℃活动积温2 100 ℃左右。适宜在黑龙江省第四积温带上限≥10 ℃活动积温2 200 ℃以上区域种植。
- Abstract:
- In order to promote the popularization and application of maize single cross hybrid Biandan 10,this paper briefly introduced the breeding process,characteristics,yield performance,cultivation technology and planting area of Biandan 10.The maize cultivar Biandan 10 which bred by Heihe Branch of Heilongjiang Academy of Agricultural Sciences is the hybrid of the female inbred line Liaozi 3370 which introduced from Shenyang Academy of Agricultural Sciences and the male inbred line FL236.This cultivar was approved in Heilongjiang Province in June 2021,and the approval number is Heishenyu 202110014.This cultivar is normal maize variety with strong seed unearthed ability and seedlings grow well.The plants have high stem toughness,developed root system,high lodging resistance and drought resistance.It resistance to corn head smut,corn northern leaf blight and stem rot.The average yield was 9 963.6 kg·hm-2 in the 2018-2019 regional test,and 8 447.0 kg·hm-2 in the production test in 2020,which was of high quality.The growth days from seedling emergence to mature was about 110 days in the adaptive area with about 2 100 ℃ active accumulated temperature which ≥10 ℃.It is suitable for planting in areas with above 2 200 ℃active accumulated temperature which ≥10 ℃ in the fourth accumulation zone of Heilongjiang Province.
