Stability Analysis for Grain Yield and Micronutrients in Bread Wheat Genotypes
Journal Title: Advances in Research - Year 2017, Vol 11, Issue 1
Abstract
This study was carried out in order to determine stability of some traits like plant height, days to heading, 1000-grain weight, grain Zinc and Iron concentrations and grain yield of fifty bread wheat genotypes. The experiment was conducted at three environmental conditions during 2015-2016 using randomized block design with two replicates. For all the traits investigated in this study, component of variation due to environment was larger than the component of variation due to genotype and G x E interaction. Different traits like plant height, days to heading, thousand grain weight, grain iron and zinc concentrations and grain yield showed range from 92.8 to 107.1 cm, from 91 to 101 days, from 32.0 to 46.1 g, from 37.5 to 45.7 ppm, from 30.2 to 41.9 ppm and from 2.1 to 3.3 kg, respectively in three environments. Two stability parameters were used to develop and evaluation of stable genotypes. The study of genotypic stability showed that the adaptation ability of the 8 genotypes (403, 413, 416, 428, 430, 435, 440 and 449) for grain Fe concentration and 2 genotypes (410 and 431) for grain Zn concentration are relatively high and they are more stable than the other genotypes. Also, genotype number 440 for grain Fe concentration, genotypes 410 and 431 for grain Zn concentration and genotypes 420 and 425 for grain yield had high mean value compared with mean value of check genotype 401 as well as high stability.
