糯玉米组合闽玉糯1号的选育

根据福建省气候、生态特点,以地方糯质及改良材料为重点种质,采用回交转育—系谱选育相结合的技术路线,育成新组合闽玉糯1号,于2002年2月通过省农作物品种审定委员会审定.多年试验表明,亲本9374、9592配合力高,性状互补性强,配成的闽玉糯1号早熟、高产、适应性广、稳产性好,春播采青生育期83-90d,秋播采青生育期72-74d.从拔节至抽雄,春季需18-21d,秋季需25-30d,该时期雌雄穗分化与营养体旺盛生长并进,是栽培管理的关键时期.

Breeding of waxy maize combination Minyunuo 1

Based on Fujian climate and ecological condition, local waxy germplasm and modified material were used as major resources to breed a new combination, Minyunuo 1, followed by the backcross pedigree technique, which had passed provincial examination in 2002. Parents Minxi 9374 and Minxi 9592 displayed high combining ability and good complementary effect in their characteristics, and Minyunuo 1 crossed with them resulted in early maturity, high yielding ability, stability and wide adaptability. Growth period of Minyunuo 1 was 83-90 days in spring or 72-74 days in autumn in Fujian. It needed 25-30 days from stem pushing to head sprouting staminate in spring or 18-21 days in autumn and it was key period of cultivation and management because of exuberant female ear differentiation and vegetation growth.
