ABSTRACT
Chillies enriched with Vitamin C and beta-carotene, traditionally are the integral part of daily food in Pakistan. Like any other agricultural produce, chillies too have been greatly affected by erratic environmental conditions. So, it is important to assess yield stability in diverse environments. Therefore, stability analysis of six chilli advance breeding lines; NARC Chilli-1, NARC Chilli-2, NARC Chilli-3, NARC Chilli-4, NARC Chilli-5, NARC Chilli-6 was carried out. F1 hybrid ‘Big Daddy’ was used as check. Plant material was figured out under Randomised complete Block Design with three replications and four locations; Chakwal, Faisalabad, Islamabad and Swat. Combined analysis of variance showed that mean yield of chilli advance lines at four locations were statistically significant. Genotype x locaton had significant interaction suggesting inconsistent performance of chilli genotypes over environments. The NARC Chilli-2 has regression slope equal to one with relatively low Wricke’s Ecovalence, low value of Shukla’s Stability Variance, relatively less value of deviation from regression and highest value of coefficient of determination. Results of stability analysis revealed that NARC Chilli-2 was the most stable line with reference to yield and this could be recomended for planting under different type of sites. NARC Chilli-6 and NARC Chilli-4 could be suitable for adequate environmental conditions while NARC Chilli-1, NARC Chilli-3 and NARC Chilli-5 for inadequate environmental conditions. Environment of Chakwal was found most productive and that of Faisalabad was poorest.
