A report in The Hindu says that scientists in the Indian state of Kerala want to increase the production of rice. Nothing special there. But the report does single out the need for “efforts on a fast track to survey, identify, catalogue and conserve all traditional plant varieties of rice as part of the measures to increase productivity”. Of course it does not say exactly how that knowledge will be used to breed better rice. But another paper at the Kerala Science Congress “Biodiversity of rice in Kerala” said that many of the traditional rice varieties offered a pool of resistant genes against insect pests. And a team of Kerala Agriculture University scientists, in its paper on the “Scope of crop diversification,” called for rice-based integrated farming system.
