摘要

摘要利用一年生野生向日葵与栽培向日葵杂交，获得了向日葵植株顶部呈黄色的自交系Mh174B。结合其他形态性状(分枝性、花粉育性恢复和射线色)，探讨向日葵植株顶部黄色的遗传控制。共建立了4个F2杂交组合:Сх1010А × Mh174B、Сх1012А × Mh174B、Сх2111А × Mh174B、Мх845А × Mh174B。结果表明，向日葵植株顶部的黄色遵循单基因遗传模式，可能是由基因y控制的。这一性状的遗传独立于分枝、花粉育性恢复和射线花颜色等性状。论述了向日葵植株顶部黄色在向日葵育种和制种中的主要应用。

A New Source of Yellow Coloration of the Sunflower Plant Top and Its Importance in Breeding

Abstract Inbred line Mh174B with the yellow coloration of the sunflower plant top was produced by hybridization of annual wild species with cultivated sunflower. The aim research was to evaluate genetic control of yellow coloration of the sunflower plant top in combination with other morphological traits (branchiness, pollen fertility restoration and ray flower coloration). A total of four F2 hybrid combinations of were created: Сх1010А × Mh174B, Сх1012А × Mh174B, Сх2111А × Mh174B, Мх845А × Mh174B. Yellow coloration of the sunflower plant top was shown to follow a monogenic mode of inheritance and, presumably, be controlled by the gene y. This trait is inherited independently from such traits as branchiness, pollen fertility restoration and ray flower coloration. The mainstreams of use of yellow coloration of the sunflower plant top in sunflower breeding and seed production are discussed.
