墨西哥野生玉米〔Zea Mexicana Schard(annual teosinte)〕是禾本科类玉米属〔Euchlaena(teosinte)〕中的一个种,是与玉米同科的近缘属植物。原产墨西哥,植株与玉米相似,呈庞大的丛生状,野生性强,具很强的抗病性。其染色体数目与玉米相同易与玉米杂交授粉,为利用其抗病性和野生性提供了条件。笔者利用其抗病性对感玉米大斑病的优良自交系金74进行改良;利用其野生性选育青饲玉米杂交种;用它与自交系杂交选育二环系。
Zea Mexicana Schard (annual teosinte), a Mexican species of corn, is a species of Euchlaena (teosinte) and is a relative of the same family as corn. Mexican origin, plants and corn are similar, showing a large cluster of wild, strong, with strong resistance. Its chromosome number is the same with that of corn, which is easily cross-pollinated with maize and provides the conditions for its disease resistance and wildness. The author uses its disease resistance to improve the susceptible inbred line Jin 74, and uses its wildness to breed the green fodder maize hybrids. Using it and inbred lines to breed the second ring system.
