摘要:

玉米机械化籽粒直收可大大节省劳动成本,对于提高种植玉米的经济效益有着重要意义,但目前适合机械化收获籽粒的品种报道较少。本研究以耐密、多抗、宜机械化籽粒直收为选育目标,通过多年多生态区域筛选和鉴定,选育出适合山东、河南区域种植的宜机械籽粒直收新品种‘浚单1668’,并分别于2019、2020年通过山东省、河南省农作物品种审定委员会审定。该品种较对照品种,平均产量增产5%以上,且抗倒伏、脱水快、宜机械籽粒收获,为提高玉米机械化收获程度降低劳动成本和保障粮食安全提供材料基础。

Abstract:

Mechanized grain harvesting of maize can greatly save labor cost, which has important significance for improving the economic benefits of maize planting. However, there are insufficient studies on maize varieties suitable for mechanized grain harvesting. This study aims at breeding maize varieties with density tolerance, multi-resistance and suitable for mechanized grain harvesting. A new variety ‘Xundan 1668’, which is suitable for mechanized harvesting and summer sowing areas in Henan and Shandong, was selected and identified in multi-ecological areas for many years. It was approved by the Crop Variety Approval Committee of Shandong Province and Henan Province in 2019 and 2020, respectively. Compared with that of the control variety, the average yield of ‘Xundan 1668’ was increased by more than 5%. The variety has lodging resistance and fast dewatering and is suitable for mechanized grain harvesting, which can be a material foundation for improving the mechanized harvesting degree of maize, reducing labor cost and ensuring food security.

Key words: maize, mechanized grain harvesting, ‘Xundan1668’, variety breeding, cultivation techniques
