Abstract

Colocasia is not being commercially grown under hill zone of Karnataka due to lack of suitable varieties and standard production technologies. Under given agro-climatic conditions, it is important to study the performance of varieties and to identify the best genotypes of colocasia with desirable characteristics for this zone. Twenty genotypes of colocasia were evaluated during Rabi 2020-21 at the College of Horticulture, Mudigere for their growth, yield and quality attributes. The experiment was laid out in a randomized complete block design with three replication. The analysis of variance exhibited highly significant differences among the genotypes for all the characters under study. Among the twenty genotypes evaluated, Piriyapattana Local performed better for most of the characteristics like plant height, number of leaves per plant, leaf length, leaf breadth, petiole length, petiole girth, leaf area, leaf area index, number of corms per plant, corm weight, corm yield per plant, tuber yield per plant, total sugars, protein and dry matter. Based on the mean performance, the genotypes Piriyapattana Local, Kushalnagar Local and Hyderabad Local are superior and high-yielding genotypes under the hill zone of Karnataka.

Conclusion

The present investigation revealed that a considerable degree of variability exists among the different genotypes of taro for growth, yield and quality traits. The best-performing genotypes identified from the present study based on the mean performance are Piriyapattana Local, Kushalnagar Local and Hyderabad Local with respect to yield characteristics. These genotypes may be recommended for commercial cultivation under the hill zone of Karnataka after yield stability analysis.
