摘要/Abstract

摘要： 本文研究了中棉（Gossypium arboreum race sinense）与纳尔逊氏棉（G. nelsonii Fryx）种间杂种F1的一些形态性状的遗传变异及花粉母细胞减数分裂的染色体行为。杂种一代呈筒形，全株密集如毡的绒毛，叶片缺刻浅，似纳尔逊氏棉。除第一朵花为闭花外，其余均为开放花，呈玫瑰红色。少数花药退化成托叶状。减数分裂中期I的染

Abstract: Insterspecifi F1 hybrid of G.arboreum race sinense (2n=26,A2) × G. nelsonii Fryx (2n=26) was analysed for its chromosome behavior in the meiosis of pollen mother cells. Observation was done on the inheritance of its morphological characters at the flowering stage. It was indicated that the interspe
