德国和法国的玉米育种

THE DEVELOPMENT OF NEW GREEN PEPPER CULTIVAR, JINONG PEPPER NO. 3

摘要:

本文介绍了德国、法国的玉米育种方法,结合我省玉米育种实际,建议:
1.开展玉米基因库的分类研究。应用测交方法,把现有种质资源划分成几个基因库;随时测定外引系并进行基因库归类。在种质资源的使用上要坚持在同一基因库内组建选系的基础材料;在杂种优势强的基因库间选用测验种。使选系的目标始终对准测验种,以求育出过硬的骨干系对手材料。
2.实行自交系选育的早代配合力测定。早代系及测交产比的多点测定。根据配合力测定结果与早代系在多环境下的自身表现选择自交系及配制组合。以此确保选出配合力高,综合性状好的材料。
3.实施并完善杂交种多点鉴定。简化杂交种在育种圃内的性状调查。把杂交种筛选的注意力集中在多环境鉴定组合的产量、抗病性、抗倒伏及稳产性上。

Abstract:

The green pepper cultivar "Jinong pepper NO. 3" is a distinct variety developed by systematilc selection for many generations following hybridization. The demonstrating cultivation of this cultivar in large area showed some advantages, such as compact plant, vigorous growth, resistance to diseases, high quality, fine-shaped fruits, good commercial quality, It yielded 52. 5% higher than cheek cultivar "Jinong square pepper".
