1963年以10KR~(60)Co-γ射线辐照锦橙干种子选育的14个优良株系无核性状的遗传性,结果表明,辐射MV_2代群体种子数具有较高的遗传力;14个株系的无核性状已基本稳定。对花瓣、叶片过氧化物酶和酯酶同工酶的数值化分析和统计分析表明,(1)对照与14个株系间同工酶谱和异度超过甜橙品种(系)间相异度。(2)过氧化物酶同工酶谱带数与种子数呈极显著正相关,二者符合直线回归方程y=a+bx,因而过氧化物酶同工酶谱带数可作为较准确地预选和鉴定无(少)核突变体的生化指标。
In 1963, the inheritance of non-nuclear traits of 14 elite lines irradiated with 10KR ~ (60) Co-γ-rays under the irradiation of dry seeds of Broccoli was studied. The results showed that the number of seeds in the MV_2 population had high heritability; Seedless nuclear-related traits have been basically stable. The numerical analysis and statistical analysis of the peroxidase and esterase isozymes of petals and leaves showed that: (1) the isozymes and isozymes of the isolates of the control and 14 lines were different from those of the sweet orange varieties degree. (2) There was a significant positive correlation between the number of bands of peroxidase isozymes and the number of seeds, which was in accordance with the linear regression equation y = a + bx. Therefore, the number of peroxidase isozyme bands could be used as a more accurate Preselection and identification of biochemical indicators of no (less) nuclear mutants.
