Abstract

WHEAT as the most important crop to man, has experienced spectacular improvements in its yield, quality and architecture during the last few decade (Feil 1992, Slafer and Peltonen-Sainio 2001, Heisey et al. 2002). In order to assess the effects of plant breeding on the yield and other characteristics of the WHEAT cultivars released by the Seed and Plant Improvement Institute, Iran during 1942 and 2007, 21 spring WHEAT varieties recommended for temperate regions were selected and sown for two successive years. Twenty genotypes were planted in a randomized complete block design with four replications. Physiological and morphological characteristics and protein content were assessed in every years. Results revealed that plant breeding has increased the grain yield through the decrease of plant height and the increase of harvest index. Number of grains per spike was higher in modern varieties that older ones. On contrary to grain yield and its components, protein content decreased significantly during the breeding process. Cluster analysis divided the cultivars into three main groups of old, medium and modern varieties. Among the traits potentially related to WHEAT grain yield, many didn’t show any trends in the Iranian WHEAT breeding history.
