Abstract
Chilli (Capsicum spp.,) is an important vegetable, spice and medicinal crop, exhibit great genetic diversity. To strengthen chilli breeding programs, a comprehensive characterization of Capsicum through morphological, physiological and molecular approaches is required. The characterization of four (04) chilli (Capsicum annum L.) varieties cultivated in Sindh province, Pakistan based on agronomic and physiological traits was carried out. The material was planted under randomized complete block design in three replications at the NIA (Nuclear Institute of Agriculture) experimental farm, for two consecutive years (2016-2017) during kharif, season. The combined analysis of variance revealed significant differences for most of the quantitative attributes of four genotypes demonstrating presence of adequate variability. The genotype Laungi-hybrid depicted the greater values for most of the traits. Correlation coefficient exhibited high degree of interrelationship among the desirable plant attributes. Fruit yield per plant exhibited highly significant positive correlation with plant height (r=0.81 canopy width (r=0.68), stem radius (r=0.87), primary branches per plant (r=0.95), leaves per plant (r=0.91), number of fruits per plant (r=0.99), fruit fresh (r=0.96), and dry weight (r=0.95), single fruit weight (r=0.84 ), and number of seeds per fruit (r=0.76), whereas, significantly negative relationship with days taken to flowering and fruiting, attributing role of early flowering and fruiting to higher fruit yield per plant. Hence, selection based on these traits may be fruitful to improve fruit yield per plant in chilli pepper
