耐湿性极强的马卡小麦（Ｔ．ｍａｃｈａ）与不耐湿的普通小麦（Ｔ．ａｅｓｔｉｖｕｍ）正反交结果表明，马卡小麦的耐湿性受核遗传物质控制。通过马卡小麦与不耐湿的普通小麦杂种一代、两个回交世代以及杂种二代的遗传分析，马卡小麦的耐湿性受１对显性基因控制
The results of reciprocal cross between T. macha and T.aestivum showed that the moisture resistance of Marca was controlled by nuclear genetic material. Through the genetic analysis of the hybrid wheat and non-moisture tolerant common wheat hybrids, two backcross generations and hybrids, the moisture resistance of Maca was controlled by one pair of dominant genes
