| Abstract: | Xin01A3 and sib-line Xin 6 were both elite inbred lines in maize, which were breeding by used maize hybrid(production test variety A in 2000) as basis material, hybridization with the tropical germplasm 8085 Thai, backcross with Chang7-2, and then selfing through many generations. Xin01A3 and Xin 6 belong to TangSiPingTou heterosis group, with the characters of mid-early maturity, high resistance, high combining ability, good quality and so on. Directly using Xin01A3, Xin 6 and their improved inbred lines as parents, many excellent maize hybrids were breeding which were approved by the provincial and national test. Among them, Xindan 68 is the first group variety suitable for mechanized harvesting approved by Henan province. Xindan 58, Xindan 65, Xindan 68 and Xindan 88 are all approved by the national test, these varieties are suitable for Huang-huai-hai summer maize planting, and suitable for mechanized operation in the whole maize production. Xindan 33, Xindan 36, Xindan 38, Xindan 61 and Yudan606 are all ordinary maize varieties with the characteristic of good quality, high yield, and high resistance. |
