STABILITY ANALYSIS FOR TUBER YIELD COMPONENTS IN POTATO (Pages : 1 - 4)

Thirty potato genotypes were evaluated for four successive years (environments) for their stability analysis using Eberhert and Russell’s model at Botanical Research Field, Rajshahi University, Rajshahi, Bangladesh during the rabi crop seasons of 2004-2008. Analysis of variance, mean, regression co-efficient (bi) and deviation from regression (s 2 di) of the individual genotypes were estimated to evaluate the stable performance of the genotypes. The mean squares due to genotypes, environments and genotype- environment interaction were significant for all the characters studied suggesting a lot of variability among the genotypes environments and the genotypes interacted significantly with environments. Among all the genotypes, Petronese and Calwhite showed stable performance for tuber number and tuber yield under all environments. The genotypes Yucon gold was highly responsive and suitable for favorable environments only. Download
