Colocasia (Colocasia esculenta L.) is an important root crop especially in the humid tropics and sub-tropics. The study was carried out at the “All India Co-ordinated Research Project on Improvement of Tuber Crops”, Central Experiment Station, Wakawali during kharif season of the year, 2016 to studied the phenotypic and genotypic associations of herbage yield were significantly positive with all plant height, number of leaves per plant and leaf length. The inter relationship between plant height and petiole length, number of leaves and leaf area were positive and significant at both phenotypic and genotypic levels. And also studies on different colocasia genotypes for calcium oxalate crystals, shelf life and starch content under konkan condition. The presence or absence of micro-character in plant system like calcium oxalate crystals has been used for understanding the palatability of the genotype. The number in calcium oxalate crystals (COCs) and starch content can differ from genotype to genotypes and it might be genetically controlled. We have studied the calcium oxalate crystals in the different plant parts (leaves and petiole), shelf life (leaves) and starch (corm and cormels) among all the colocasia genotypes. The calcium oxalate content in terms of raphide counts per 200 microscopic field was varied from 58.47 to 251.00.The genotype BCC-11 contained less amount of calcium oxalate (40.40 r 200-1 mf). The starch content was varied from 13.57 % and 24.13 % and significant difference was observed for shelf life of leaves (10.42 to 13.95 hrs) among different colocasia genotypes.
