Evaluation of Tapioca Genotypes for Growth and Yield Parameter

Abstract

The experiment on twenty six tapioca genotypes was laid out to evaluate their performance in terms of root yield. The genotypes significantly differed in respect of root yield plantper plant. The highest root yield (t ha-1) was recorded by the genotype H-226, a hybrid between a local cultivar and Malayan introduction M-4. H-226 was followed by H-97 which is a hybrid between a local variety and a Brazalian selection. It can be concluded that a significant variation in root yield could be seen in different tapioca genotypes due to their differential behavior in respect of growth, number of roots/plant and yield/plot (kg). Tapioca genotype H-226 gave the maximum root yield of 37.21 (t ha-1) with SVI (0.82) and B:C ratio of 3.16
