Breeding of waxy maize combination Minyunuo 1 |
| |
Abstract: | 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. |
