【摘要】 本文对化学诱导玉米孤雌生植获得的Pa2代161个株系进行了分析，调查了它们的株高、穗位高、穗上叶数、穗长、穗行数、行粒数和百粒重，其中有38个株系（约占23％）表现整齐一致，这些株系的几种同工酶谱带和盐溶蛋白谱带也表现相同，说明属纯合系。更多还原

【Abstract】 161 Pa2 chemical - induced parthenogenesis lines in maize were investigated according to their plant height, ear height, leaves over ear per plant, rows per ear, seeds per row and 100-grain weight. 23% of them, 38 plant lines, performed uniformly on these characteristics. All these plant lines also exlibited the same on serveal isoenzymes and salt solution protein. They are pure lines.更多还原
