SAIMA MIR ARAIN
Abstract
Chilli (Capsicum spp.,) is an important vegetable, spice and medicinal crop, exhibit great genetic diversity. To strengthen chili breeding programs, 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 of Pakistan was carried out based on agronomic and physiological traits. The material was planted under randomized complete block design in three replications at the NIA (Nuclear Institute of Agriculture) experimental farm, during kharif 2016. The analysis of variance revealed significant differences for most of the quantitative traits of four varieties indicating presence of sufficient variability. The cultivar Hybrid depicted the greater values for most of the traits. Correlation coefficient exhibited high degree of association among the important plant traits. 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 association with days to flowering and fruiting, attributing role of early flowering and fruiting to higher fruit yield per plant. Hence, selection on the basis of these traits may be fruitful to improve fruit yield per plant in chilli pepper.
