Character association studies by correlation estimates of diverse carrot germplasm lines evaluated under tropical climate

Abstract

Ninety six germplasm lines of carrot collected from different parts of India were evaluated on the basis of 33 phenotypic traits (18 quantitative and 15 qualitative) in an Augmented block design comprising of 3 checks (Ghataprabha Local, Vigro Kuruda and Pusa Vrishti) with 6 blocks was utilized to screen the genotypes comprising of temperate and tropical types with diverse colors at University of horticultural Sciences, Bagalkot during winter season from August-December, 2016. Correlation analysis was carried out to study the character association by Pearson’s correlation coefficient analysis among root morphological and biochemical traits of carrot genotypes for the identification of appropriate selection indices. Genotypic correlation coefficient analysis revealed that root weight, root length, leaf width, petiole length, leaf length and root diameter had significant positive correlation indicating their effectiveness in selection for higher productivity in carrot.
