| This experiment was done in order to determine superior lines and to introduce the cultivars with high performance and productive potentiality of wheat. In this research 17 selective advanced lines from the yield comparison experiments were investigated in the Kabotarabad region of Isfahan, in comparison with Bahar cultivar as control, in a complete randomized blocks design with three replications in 2011-2012 cropping year. Quantitative traits assessed were including plant height, flag leaf length, leaves number, spike length, peduncle length, tillers number and grain yield. The obtained results of variance analysis of the tested traits showed that studied lines had significant difference at one percentage probability level as compared with control cultivar and with each other. The maximum height of plants was belonged to line No.12 with 105 cm and the least height of plants was allocated to lines No. 4, 9 and 10 and with 87.6, 88 and 87.6 cm, respectively. Also, based on the obtained results of comparing the average grain yield, it was determined that the highest grain yield was line No. 18 with 9.70 tons per hectare and the lowest one was allocated to line No. 16 with 8.30 tons per hectare .The investigation of the correlation table of tested traits showed that the correlation coefficient of grain yield with plant height showed no significant effect and was reversed. However, the correlation coefficient of the plant heights with leaf length with the negative effect was significant at one percent probability level (r= -0.569). The obtained results of cluster analysis chart of the tested lines and quantitative traits studied in this research indicate significant difference between the tested treatments. |
