White Yam, a tuber crop that satisfies the caloric need of more than 300 million people around the world and due to its palatability and better yield qualities, it is widely cultivated in Indian state, Kerala. Studies showed that 30 % of cost of cultivation of this crop is attributed to staking materials for trailing, and this limits the wider spread of cultivation across the country. Hence, a research program was designed to identify Single Sequence Repeat (SSR) marker linked to dwarfness in white yam, so that, it helps to develop and modify the plant architecture from trailing to dwarf type to reduce the cost of cultivation, labour charge and to increase easiness of its farming. Thirty various accessions of white yam, comprising dwarf, semi dwarf and tall varieties, were screened for genetic polymorphism using a set of 10 SSR markers. On analysis, significant polymorphisms were shown which discriminating across the genotypes evaluated. It is observed that, one SSR marker showed a unique band of 1.5Kbp for dwarf genotype and the sequence analysis of this product showed 90% identity to a gene from Chowghat green dwarf cutivar of Cocos nucifera, which can be used in marker assisted selection for dwarf varieties.
