Abstract:

Breeding and high-yielding cultivation technology of super-maize hybrid was a hot spot in crop production at present. Based on utilization of heterosis, aiming at compact and multi-resistant, the super-maize hybrid ‘Ludan818’ was bred through 10 years, which creationarily abhibited some new breeding technology including ukrainian maize germplasm, parthenogenesis technology, population improvement. The technical route and process of ‘Ludan818’ breeding, variety character was described in details, and breeding objective and technical route of super maize were discussed. At the same time, the high-yielding cultivation technology of ‘Ludan818’ was set after about 5 years of high-yielding technology research to achieve finy varieties combining with suitable cultivation method.
