The Effect of the Rht1 Haplotype on Fusarium Head Blight Resistance in Relation to Type and Level of Background Resistance and in Combination With Fhb1 and Qfhs.ifa-5A
Abstract:The semi-dwarfing reduced height alleles Rht-D1b and Rht-B1b have been deployed in modern wheat cultivars throughout the world, but they increase susceptibility to Fusarium head blight (FHB). Here, we investigated the impact of the Rht1 genes on anther retention (AR) in relation to FHB resistance using four different sets of near isogenic lines (NILs) with contrasting levels and types of background FHB resistance. NILs were evaluated for FHB severity, plant height, and anther retention in three greenhouse and … Show more
