Root-based characterization of intergeneric hybrids with Triticum and Aegilops species in early vegetative and stem elongation growth stages

Cultivated and wild species of wheat are valuable breeding resources used for the development new cultivars with superior root traits suited to drought non-stressed conditions. The present study aimed determine genotypes phenotypic variability among intergeneric hybrids Triticum Aegilops in early vegetative (Z11) stem elongation (Z31) growth stages. Results indicated that rooting depth was 3.2- 3.4-fold Z11 Z31, it as great 20- 23.8-fold biomass, respectively. Hierarchical clustering 35 both stages identified four major clusters, grouping six deep-rooted cluster 2 three high biomass 1. In stages, significant associations were found traits. Also, relationship stronger between shoot (r2=0.83) than Z31 (r2=0.44). As an overall assessment, suggested characteristics such deep roots and/or sustained might be cultivars.
