Phenotypic selection, for accumulating the desirable characters to develop the crops tailored as per our need, has been the basis of the plant breeding since the time immemorial. But with the several issues associated with this approach viz., huge time, resource and space intensive approach, researchers are on continuous journey to explore more efficient approach with high throughput that could substantially deduct the time and resource requirement with high fidelity. With the advent of several molecular markers, newer avenue of the crop improvement has been explored and marker-assisted recurrent selection stand out to be an intensive approach, which has provided the breeder an efficient tool to use his skills more rigorously. Shortening the time while enhancing the selection efficiency and, thus improving the overall genetic gain has made this approach the need of the hour and choice of the breeders. This review takes you to the journey of its advent and its potential role in population improvement in both self- and cross-pollinated crops.

通过标记辅助的循环选择增强遗传收益:从表型到基因分型

自古以来,表型选择就是为了积累理想的性状以开发根据我们的需要量身定制的作物。但是由于与这种方法相关的几个问题,即大量的时间、资源和空间密集型方法,研究人员正在不断探索具有高吞吐量的更有效方法,该方法可以高保真地大幅减少时间和资源需求。随着几种分子标记的出现,已经探索了作物改良的新途径,标记辅助的循环选择作为一种强化方法脱颖而出,这为育种者提供了更严格地使用其技能的有效工具。缩短时间,同时提高选择效率,因此,提高整体遗传增益使这种方法成为育种者需要时间和选择的方法。这篇评论将带您了解它的出现及其在自花授粉和异花授粉作物种群改善中的潜在作用。
