Description Accepted date: 12 August 2013
Adaptations to different habitats across the globe and consequent genetic variation within rice have
resulted in more than 120,000 diverse accessions including landraces, which are vital genetic resources for
agronomic and quality traits. In India the rice landraces of the states West Bengal, Assam, Mizoram, Manipur and
Nagaland are worthy candidates for genetic assessment. Keeping the above in view, the present study was
conducted with the aim to (i) calculate the genetic distances among the accessions of 83 landraces collected from
these states along with 8 check accessions (total 91 accessions) using 23 previously mapped SSR markers and (ii)
examine the population structure among the accessions using model-based clustering approach
The authors wish to thank National Bureau of Plant Genetic Resources, India,
Assam Agriculture University, Agricultural Training Centre Fulia, Rice Research
Station Chinsurah, and State Agricultural Research Farm Kashipur for
providing us with rice accessions. They also wish to thank the Department of science and Technology for providing the research funding through Bose
Institute and for providing the fellowship to Basabdatta Das. We also thank
the University Grants Commission for providing fellowship to Samik
Sengupta through Calcutta University.
