大面积推广种植杂交棉是提高棉花产量的重要途径之一。我场自2005年引进种植杂交棉标杂A_1以来,体现出其增产效果显著、优质及多抗等特点。开展标杂A_1杂交棉制种工作,在实践中探索总结出新疆北疆气候条件下杂交棉高效制种关键技术,以及杂交棉制种模式,为带动垦区杂交棉制种和杂交棉的生产发展提供依据。1亲本材料来源标杂A_1是利用两个纯合的有标记性状的自交系杂交而成。由于双亲自交系的遗传异质性大,杂交优势较强。
Extensive promotion of hybrid cotton cultivation is one of the important ways to increase cotton yield. Since the introduction of hybrid cotton A10 in 2005, my field has shown its remarkable yield increasing effect, high quality and multi-resistance. To carry out the work of standard hybrid A_1 hybrid cotton seed production, explore and conclude in practice the key technologies of hybrid cotton efficient seed production under the climate conditions of northern Xinjiang and the hybrid cotton seed production model, in order to promote the production of hybrid cotton seed and hybrid cotton in reclamation area Provide evidence. The parent material A10 is derived from two inbred lines with homozygous labeled traits. Due to the genetic heterogeneity of parents inbred lines, hybrid superiority.
