| Gaia: | Rice landraces of Kerala State of India are named based on cropping season, growing conditions, crop
duration, morphological features, color of seed and other specific traits, if any. The collections of
landraces of Kerala are classified as rare, very rare and common. A part of these collected accessions
have been characterized. DIVA-GIS was used to map the collection site, which showed that the
collections made are well distributed throughout Kerala but very meager collections are represented
from Thiruvananthapuram and Pathanamthitta Districts. Till about 20 years back, all the paddy fields in
Kerala were being cultivated with various landraces of rice during the southwest and northeast
monsoon seasons. Currently, these paddy fields are being progressively filled with soil transported
from other places and converted into building sites or sites for growing other upland crops. As a result
of this, a large number of primitive cultivars and local landraces of rice have been lost. Genetic erosion
can be assessed and target areas for collection in diversity rich area can be predicted based on
resurvey of the collection localities and mapping the collection localities using DIVA-GIS tool. The
present paper describes the rice landraces of Kerala with their specific location from where they have
been collected. |
