Kenaf (Hibiscus Cannabinus L.) Breeding

ABSTRACT

Kenaf (Hibiscus cannabinus L.) is an important bast fiber crop, and a source of fiber to many industries. This crop is diploid (2n = 2x = 36) in nature, and belongs to Malvaceae family. Kenaf breeding is directed to develop the new cultivars that are better in fiber production, fiber quality, resistant to anthracnose, photo-insensitivity, resistant to salt and drought stresses, and so on. This review describes the various successes in kenaf breeding, and reports the future opportunities. The various classical and advanced breeding approaches have great potential to achieve the goals. However, the recent approaches in plant breeding and biotechnology could have more prospective to accelerate the kenaf breeding. These may include genomic selection, CRISPR/Cas9 gene-editing system, and other omics-based approaches. We suggest that the integration of recent approaches with classical ones has vital importance in improving the efficiency, speed, and accuracy of kenaf breeding.

摘要

红麻 (Hibiscus cannabinus L.) 是一种重要的韧皮纤维作物, 也是许多工业行业的纤维来源. 本作物为二倍体 (2n=2x=36), 属锦葵科. 红麻育种的目标是培育出纤维产量高, 纤维品质优, 抗炭疽病, 光周期不敏感, 耐盐旱等优良品种. 本文介绍了红麻育种的各种成功经验, 并对今后的发展前景作了展望. 各种经典的和先进的育种方法有很大的潜力来实现这一目标. 然而, 近年来在植物育种和生物技术方面的研究对加速红麻育种具有更大的前景. 这些可能包括基因组选择, CRISPR/Cas9基因编辑系统和其他基于组学的方法. 因此, 将现代育种方法与经典育种方法相结合, 对提高红麻育种的效率, 速度和精度具有重要意义.
