Identification of new QTLs for quality traits and yield using tetraploid wheat interspecific backcross inbred lines.

ABSTRACT:

Background

The wild tetraploid wheat Triticum turgidum var. dicoccoides is a valuable source of genetic variation for improving disease resistance, drought tolerance, and grain protein quantity and quality in cultivated wheat. However, little is known about the genetic basis of DNA introgression from wild relatives into cultivated backgrounds. Because wild germplasm contains both favorable alleles and undesirable agronomic traits, understanding segregation and recombination patterns is essential for its effective use in breeding. This study aimed to evaluate a population of backcross inbred lines (BILs) derived from T. turgidum var. dicoccoides to identify quantitative trait loci (QTL) associated with grain quality and yield-related traits.

Results

The BIL population was eva
