Response to moisture stress of wheat near-isogenic lines varying at Ppd and Vrn genes – Yanco 2018

Abstract

Key findings •• Under moisture stress conditions, early flowering and long grain-filling duration were advantageous in 2018. •• Short-season spring type near-isogenic lines (NILs) yielded better than winter types under moisture stress growing conditions at this site in 2018. •• The highest yielding line under moisture stress conditions had spring alleles in all Vrn genes and insensitive alleles in all Ppd genes. •• Under irrigated conditions the highest yielding lines had at least one spring Vrn allele and one Ppd insensitive allele.
