Abstract[English]
Provided is a method for increasing the kernel row number of an ear of corn, increasing the width of the ear of corn, increasing corn kernel weight or improving corn yield. The method comprises the step of mutating the CLE gene in corn. The mutation of the CLE gene can lead to increases in the kernel row number of an ear of corn, ear width, kernel weight and yield thereof. Therefore, the method has important application value in corn breeding.[French]
L'invention concerne un procédé d'augmentation du nombre de rangées de grains d'un épi de maïs, d'augmentation de la largeur d'un épi de maïs, d'augmentation du poids de grain de maïs ou d'amélioration du rendement de maïs. Le procédé comprend l'étape de mutation du gène CLE dans le maïs. La mutation du gène CLE peut conduire à des augmentations du nombre de rangées de grains d'un épi, de largeur d'un épi, du poids des grains et de son rendement. Par conséquent, le procédé présente une valeur d'application importante dans l'amélioration génétique du maïs.[Chinese]
提供了一种增加玉米穗行数、增加玉米穗宽、增加玉米粒重、或提高玉米产量的方法，所述方法包括将玉米中CLE基因进行突变的步骤。所述CLE基因突变后可以导致玉米的穗行数、穗宽、粒重增加和产量提高，在玉米育种中具有重要的应用价值。
