Abstract

Eight peanut genotypes were grown at two locations during four successive summer seasons from 2014 to 2017 to give eight environments in order to evaluate yield stability. Significant genotype × environment interaction was detected for all traits. Results revealed that peanut genotypes Sohag116, Sohag119 and Sohag120 were superior in their mean performance for yield and yield components, The regression coefficient value was approached unity in genotypes VAC-R92, Sohag nos. 116, 119 and 120 also, pod weight and seed weight, genotypes Sohag nos. 116 and 119 as well as number of pods and number of seeds plant-1 genotypes Giza 6, Line 9, VAC-R92 and Sohag 119 as well as shelling percentage, genotypes Sohag 112, Line 9, Introduction 508 and Sohag 120 as well as 100-pod weight, genotypes Sohag 112, Introduction 508 and VAC-R92 for 100-seed weight genotypes Sohag 112, Line 9, Introduction 508 and Sohag 116 for pod yield fed-1., where the value of bi almost approached unity, indicating average response to the fluctuating environmental conditions prevailed. Genotypes VAC-R92, Sohag nos. 116 and 120 had the highest pod weight plant-1, number of pods plant-1, number of seeds plant-1 and seed weight plant-1 among the tested genotypes, as they had high mean of pods (50.19) over population average mean of pods plant-1 (46.5) peanut genotypes VAC-R92, Sohag nos. 119 and 120 for 100- pod weight (g), genotypes Sohag nos. 116 and 119 for 100-seed weight (g), genotypes Sohag nos. 116, 19 and 120 for pod yield fed-1 (ard.). These genotypes are suitable especially for favorable growing seasons as they had nearest (bi) value to 1. genotype Sohg112 recorded the highest number of pods plant-1 over the grand mean, whereas genotypes Sohag nos. 116 and 120 gave highest shelling percentage, genotype Sohag116   gave the highest 100-pod weight and Sohag120 gave the highest number of seeds plant-1 indicated that these genotypes are fitted, for less favorable locations as they had low (bi) value (b<1). Such genotypes can be utilized in a breeding program for transferring stability characters in to high yielding cultivars peanut as genotype 8 which was the best one.
