Abstract:
Carrot is the tenth most economically important vegetable crop in the world. Though, its production is limited across different ecological regions due to genotype instability and environmental variability. This research was carried out to examine the magnitude of environmental effect on performance of carrot genotypes and to investigate the stability and adaptability of genotypes under subtropical region of northern dry zone of Karnataka. As the performance of each cultivar tends to vary when grown in different seasons, hence, seven genotypes were evaluated in 2017, 2018 and 2019 during regular season of carrot from September-December. Eberhart and Russell model of stability analysis was carried out which revealed a significant effect of each season on the cultivars taken for all the seven morphological traits. None of the genotype was found stable for all the traits across seasons and stability of each trait was independent from one another. Thus, it emphasized the need for the development of trait specific cultivars that are stable across seasons.
