The study of correlation between traits evaluated at farm and laboratory conditions at 58 lines and varieties of bread wheat
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 11
Abstract
Triticum aestivum is the most important crop in the world. This study was designed at the Agriculture and Natural Resources Research Station of Ardabil and Agriculture Laboratory of Islamic Azad University, Ardabil Branch in 2011-2012 crop years. In this experiment, 55 wheat lines and three varieties were investigated as control. This study was conducted in laboratory in a randomized complete block design (CRD) with three replications and was conducted in farm augmented design so that controls cultivars was examined with three replications and new lines were broadcast randomized into the three replications. The results showed that there were significant and positive relationship between spike weights with spike length, number of spikelet per spike, number of grains per spike, grain weight per spike and 1000 grain weight. Also results showed that there is a positive and significant relationship between grain weights per spike with 1000 grain weight (r=0.578**), in other words, 1000 grain weights are also increased with increasing grain weights per spike. The results showed that there was positive and significant relationship between germination speed coefficient with all traits and this relationship was negative and significant with germination time mean. In other words, all traits are increased with increasing germination rate, in case, mean germination time mean is reduced.
