Abstract
Mehrnoosh Alipour, G.A. Ranjbar, Saeed Khavari Khorasani, N.A. Babaeian.
This experiment was conducted to study the effects of water deficit stress on morphological traits, yield and its components for 60 maize single cross hybrids which was laid out in randomized complete block design (under normal and drought stress conditions), with three replications at Torough Agricultural and Natural Resources Research center located in Mashhad, Iran. Results of ANOVA showed significant differences among single cross hybrids for all measured traits in both conditions. In non-stress or normal condition, hybrids No.4 and in stress condition, hybrids No.9 were the best hybrids for grain yield with 13.30 and 9.02 ton-ha-1, respectively. According to cluster analysis, hybrids were divided into 4 categories. Group C was the best group for grain yield that yielded 10.27 ton-ha-1. Hybrids No.25 can be recommend for using in plant breeding programs.
