利用陆地棉与海岛棉杂种一代优势生产细絨棉不仅成熟提早,增产显著,而且纤维品質接近或超过海島棉亲本,对發展我国细絨棉生产提供了新途徑。 綜合近年来各地研究结果,陆海杂种一代优势的强弱,决定于亲本类型的遺傳基础和当时的生長發育条件。由于不同地区适应的棉花品种不同,杂种的产量因杂交组合的不同而差異很大。因此杂种
It is not only mature and early yield increase, but also the fiber quality close to or over the parents of island cotton, which provides a new way for the development of fine cotton production in our country. Based on the findings of recent years, the strengths and weaknesses of the heterosis of land and sea hybrids depend on the genetic basis of the parental type and the conditions for growth and development at that time. Due to the different cotton varieties adapted to different regions, the yield of hybrids varies greatly depending on the hybrid combinations. So hybrid
