应用外源DNA直接导入植物技术 ,将不同种属的单子叶植物总DNA分别导入普通小麦 ,调查其后代产生的变异 ,对D2 代株高、穗粒数、千粒重 3个性状的变异进行分析研究
Direct introduction of exogenous DNA into plant technology, the total genomic DNA of monocotyledonous plants of different species were introduced into common wheat respectively to investigate the variation of their offspring generation. The variation of plant height, grain number per spike and grain weight per 1000-kernel weight of D2 were analyzed
