Title

EVALUATION OF WHEAT YIELD AND RELATED TRAITS VARIATION IN TEMPERATE SEMI-HUMID CONDITIONS

Pages

  17-33

Abstract

 In order to study variation of WHEAT yield and its traits, a field experiment was conducted based on randomized complete block design with 16 treatments and 3 replications at Agricultural Research Farm, Gorgan, Iran in the growing seasons of 2007-2008 and 2008-2009 under well-watered conditions. The results showed that number of nodes, number of tillers per plant, number of grains per spikelet and seed weight were not change during breeding activities. Number of grains per spike and grain number per unit area increased 28.87% and 24.74%, respectively during 38 years of the release, 0.78% and 0.80% improvement per year was observed, respectively. The most important reason for increasing the number of seeds per square meter was increasing GRAIN NUMBER PER SPIKE. In GRAIN YIELD, biological yield and HARVEST INDEX increase has been equal to 24.83%, 16.16% and 8.18% respectively. Also plant height was decreased by 0.25% and spike length was increased by 0.27% per year of release. Generally, more than 89% yield variation was justified by changing variables such as HARVEST INDEX, biological yield and GRAIN NUMBER PER SPIKE.
