摘要
ＣＩＭＭＹＴ基因圃Ｐｏｏｌ３４ＱＰＭ种质的中群１４号Ｃ０～Ｃ５各轮群体，在陕西夏播条件下各性状表现的综合评价：中群１４号Ｃ０～Ｃ５各轮群体逐轮光周期敏感性下降，自身生产力提高，高轮群体农艺性状基本同于温带同类杂交种。建议将高轮中群１４号改换方法继续改良，或以其作为修饰基因供体与同类软质胚乳杂交，选育硬质、半硬质胚乳Ｏｐａｑｕｅ－２玉米温带群体、自交系或直接选系利用，以期组配出新的优质蛋白玉米高产组合。
A comprehensive appraisal of all the traits of the C. Pop 14 C0～ C5maize population of summer sewing in Shaanxi Province suggested that the higher the selecting transmigration was, the lower the photo-temperature sensitive and the higher the population yield was. The Comprehensive traits were closely similar to the temperature zone crossed varieties. It is recommended that the high rotating C. Pop 14 QPM need further improvement or eross be carried out between the soft endosperm materials to select hard endosperm opaque- 2 maize populations for the purpose of cultivating an optimum combination of maize with high yields and quality proteins.
