Genetic diversity among taro (Colocasia esculenta (L.) Schott var. antiquorum) germplasm- A review

摘要

Taro (Colocasia esculenta (L.) is one of the important underground vegetable crops grows vegetatively in various parts of India as well as in Africa. But there are few standard cultivars available for commercial cultivation and local germplasms acrossvarious parts of the world have a lot of genetic variation. For any crop improvement programme, aimed to achieve maximum productivity, a detailed knowledge of facts such as genetic variability, genetic diversity, heritability, genetic advance, correlation and path coefficient of various quantitative traits and their contribution towards yield is essential. Studies in this direction are very less and can not to be generalized for every climatic condition and with other genetic materials. Hence, the information in a collection of some indigenous genotypes of taro in order to formulate a sound breeding plan for its improvement has been reviewed here.
