在前期已获得耐盐转OsCDPK7、OsMAPK4基因水稻的基础上,对转基因株系的产量性状、生物学性状、品质性状和生育期等农艺性状进行调查与分析。结果表明,在田间栽培条件下,转基因水稻植株个体生长发育正常,转OsCDPK7基因水稻株系主要农艺性状与对照无差异;而转OsMAPK4基因水稻株系与其受体之间单位面积产量、株高、有效穗数和粗蛋白含量等均存在显著差异。这种差异与OsMAPK4基因功能存在必然关系。 On the basis of obtaining salt tolerant transgenic rice plants OsCDAPK7 and OsMAPK4, the yield traits, biological traits, quality traits and growth stages of transgenic lines were investigated and analyzed. The results showed that under the conditions of field cultivation, the transgenic plants had normal growth and development, the main agronomic traits of OsCDPK7 transgenic rice plants were the same as those of the control. However, the yield per unit area, plant height, There were significant differences in effective panicle number and crude protein content. This difference is related to the function of OsMAPK4 gene.
