Crop health is acknowledged as a key component to secure global food security. Pisum sativum L. (pea) cultivation is questioned by different biotic, and abiotic stresses. Among them, pea root rot complex (PRRC) is the most prevalent disease caused by soil-borne fungi, and it is usually considered the limiting factor in pea yield (30–57% reduction in yield). PRRC has a diverse spectrum of hosts and may be found all around the globe. The condition stands complex, and numerous approaches such as cultural, physical, biological, and pharmaceutical have failed miserably to control PRRC pathogens. In light of the many tactics and their success, host-plant resistance represents just one realistic choice for controlling the disease in pea agriculture for the long run. It's a strong, low-cost, long-lasting, and environmentally sustainable phenomenon. Plant breeding strategies along with advanced molecular approaches viz., SNP genotyping, gene(s), QTLs mapping, marker assisted selection (MAS), have been led to rise of host-plant-resistance against PRRC. Partial resistance to Fusarium spp. is more common in pea genotypes with coloured flowers and seed coatings. MAS can speed up the breeding process by assisting in the genetic selection of targeted traits in early generations. QTLs for resistance to PRRC can be validated using NILs/RILs generated by MAS. In the present manuscript, we review the recent results and breeding strategies for PRRC.

豌豆根腐复合体的全球维度:现状和育种前景

作物健康被公认为是确保全球粮食安全的关键组成部分。豌豆L.(豌豆)栽培受到不同的生物和非生物胁迫的质疑。其中,豌豆根腐病(PRRC)是由土传真菌引起的最常见病害,通常被认为是豌豆产量的限制因素(减产30-57%)。PRRC 的主机种类繁多,遍布全球。这种情况很复杂,许多方法,如文化、物理、生物和药物,都无法控制 PRRC 病原体。鉴于许多策略及其成功,寄主植物抗性只是长期控制豌豆农业疾病的一种现实选择。这是一种强大、低成本、持久且环境可持续的现象。植物育种策略以及先进的分子方法,., SNP 基因分型、基因、QTLs 作图、标记辅助选择 (MAS) 已导致宿主植物对 PRRC 的抗性上升。对镰刀菌的部分抗性。在具有彩色花朵和种皮的豌豆基因型中更为常见。MAS 可以通过协助早期几代目标性状的遗传选择来加快育种过程。可以使用 MAS 生成的 NIL/RIL 来验证 PRRC 抗性的 QTL。在本手稿中,我们回顾了 PRRC 的最新结果和育种策略。
