1Department of Biotechnology,
Indian Institute of Technology Guwahati, Assam 781 039, India
ABSTRACT
Rice is a widely grown staple food crop for half of the world’s population. Assam being one of the
centres of origin has got wide range of variation of rice cultivars. Among all the common cultivars,
aromatic rice of this region enjoys a top position in terms of popularity. The Joha rice cultivars are
known for its unique aroma, superfine kernel, good cooking qualities and excellent palatability.
Except elongation ratio, Joha cultivars of Assam have compatible aroma and quality as that of other
scented rice of India. However, the class of aromatic rice has not been studied by researchers and
workers due to various constraints. Only some preliminary breeding works and tissue cultures are
done till date in local research stations and universities. Unfortunately, many of them have now
become extinct. In this review, the scattered information and data on Joha rice cultivars of Assam are
being tried to put together which could be useful for further studies on this valuable and endemic
rice variety. This could eventually be helpful in drawing the attention of the researchers and scientists
to work on it.
