Registration of Fusarium Head Blight-Resistant Soft Red Winter Wheat Germplasm VA04W-433 and VA04W-474 Academic Article uri icon

abstract

  • Fusarium head blight [FHB; caused by Fusarium graminearum Schwabe; telomorph Gibberella zeae (Schwein.) Petch] is one of the major diseases of winter wheat (Triticum aestivum L.) in the U.S. midAtlantic region. The objective of this research was to develop adapted soft red winter (SRW) wheat germplasm having enhanced resistance to FHB for this region. The SRW wheat germplasm lines VA04W433 (Reg. No. GP943, PI 657945) and VA04W474 (Reg. No. GP944, PI 657946) are two adapted FHBresistant lines developed by the Virginia Agricultural Experiment Station and released in 2009. VA04W433 was derived from a threeway cross of Ning 7840/Pioneer brand 2684//VA9654244. VA04W474 is a doubled haploid line derived from the F1 of the threeway cross Roane//W14/Coker 9134 using a wheatbymaize hybridization method. The resistance was derived from known Chinese resistance sources Ning 7840, in VA04W433 and, W14, in VA04W474 and selected through intensive phenotypic screening. The resistance was confirmed with molecular markers on chromosome 3BS and 5AS. Both lines have better grain volume weight, better resistance to deoxynivalenol accumulation caused by FHB infection, and better resistance to leaf rust (caused by Puccinia triticina Eriks.) than the resistant check Ernie.
