| 摘 要： | 以不同剂量的氮离子对3个大豆品种的干种子进行注入诱变处理后,对M4代主要农艺性状、生育期和蛋白质含量及脂肪含量的遗传变异进行了研究,结果发现,不同品种结荚高度对同一剂量诱变的敏感性相同,其他农艺性状的诱变敏感性不同;同一品种结荚高度对不同剂量的诱变敏感性相同,其他农艺性状的诱变敏感性不同。离子注入可以显著缩短大豆生育期,不同品种对同一剂量注入诱变的敏感性相同,同一品种对不同剂量的诱变敏感性也相同。离子注入可以对大豆蛋白质含量和脂肪含量有显著的改良,不同品种对同一剂量注入的诱变敏感性不同,同一品种对不同剂量的诱变敏感性也不同。

| Abstract: | In this study,three soybean cultivars were implanted with N ion,and the genetic variation of main agronomic characters and life duration and protein content and oil content were studied with M4 generation.The result showed that the different cultivars had the same radiosensitivity of one implanted dose on the height of 1st pod,the radiosensitivity varied among other agronomic characters,the same cultivar had the same radiosensitivity of different implanted doses of height of 1st pod,the radiosensitivity varied among other agronomic characters.Growth period of soybean could be obviously shortened by implanted with N ion,the different cultivars had the same radiosensitivity of one implanted dose;the same cultivar had the same radiosensitivity of different implanted doses.Soybean protein content and oil content were improved notably by implanted with N ion,the different cultivars had different radiosensitivity of one implanted dose.The same cultivar had the same radiosensitivity of different implanted doses. |
