【摘要】 对４个红麻品种（系）ＳＰ２代的观察结果表明：红麻一号和９１７两个红茎品种（系）出现了绿茎变异；绿茎圆叶的７１４Ｂ中有两个株行全为裂叶，可能是ＳＰ１代雄性不育株与邻近的裂叶型品种异花授粉的结果３８３１０干种子经６０Ｃｏ辐射处理的Ｒ１代种子又经卫星搭载的ＳＰ２代明显表现为生长旺盛、植株高大，并出现了较多的花柱伸长变异．更多还原

【Abstract】 The SP2 generation of 4 cultivars (or lines) in kenaf were investigated. Some stems of Hongma No.1 and 917 (a line) with red stems presented green. All the plants in 2 plots of 714 B with green stems and cordate leaves occured the variation of split leaves, those conjectured which might be the offspring of male sterile plants that occured in 714 B SP1 crossing with split leaves cultivars. The plants in the SP2 generation of 8310 (a line) which was R1 generation of radiation with 60Co, grew vigorously and presented more variations of protrusion of styles.更多还原
