我国现有薏苡品种普遍存在产量低、易倒伏、晚熟、抗病虫性弱等问题,缺乏优质薏苡新品种,严重制约了薏苡生产的发展。因此,从薏苡种质资源、杂交育种、组织培养及倍性育种、人工诱变育种4个方面,综述了近年来薏苡遗传育种的研究现状和进展。针对当前育种存在的问题,应以种质资源为基础,结合常规育种、现代生物技术育种,建立一套完整的选育体系。
Coix lacryma-jobi L. is an important plant which has eating quality and medicinal values, and has potential for development. However,the seeds production is quite low. Lodging, late maturity,lower resistance to insect pest happened often. Lacking of new variety of higher quality seriously restrict the de-velopment of Coix lacryma-jobi L. Therefore, from study on germplasm resources, cross-breeding, tissue culture and ploidy breeding of Coix lacryma-jobi L. , the research status and progress of genetics and breeding were reviewed in recent years. We would establish a complete set of breeding system on the basis of germplasm resources,combined with the conventional breeding and modern biotechnology breeding in view of the current problems of breeding.
