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.
Sachs in Kenya
Professor Jeffrey Sachs, director of the UN Millennium Project, is in Nairobi, and The Nation reported yesterday that he “said … giving farmers high yield seeds, fertiliser and mosquito nets to prevent malaria infection would accelerate the country’s economic growth.” He quoted the experience of the Millennium Villages: at Sauri in Siaya District, for example, cases of malaria have dropped by half since the distribution of free mosquito nets and last year the harvest was four times bigger than two years ago. I have no issue with the malaria interventions, but does anyone really still think that “high yield seeds” and fertilizer are the sole answer to agricultural development in Africa? Couldn’t Prof. Sachs have said something about the importance of diversity too?
A tale of two genes
From FoodNavigator, two stories about cool genes: one from an orange cauliflower that could be used to increase beta-carotene in other crops, and one from coffee that could make for a better-tasting cup. It’s always fun to hear about such genes. Now comes the hard part, I guess.
How breeders use genome information
Everything you’ve always wanted to know about the use of genomic information in plant breeding but were afraid to ask is covered in a feature article from the US Department of Agriculture. Well, not quite everything, but Improving Crop Plants Through Genomics does offer a quick run down on some of the techniques and some of the projects, including one on nutritional quality and others on marginal environments and pests and diseases.
Opium poppies
There are a couple of interesting articles in this week’s print issue of The Economist, but they are both premium content on the web, so I’ve dug a bit deeper for you and will post on them separately. One article contrasts the global shortage of opiates for medical use with the efforts being made to stop Afghani farmers growing the opium poppy for the heroin trade. A crazy situation. One possible solution is licensing farmers to grow the crop under strict controls, but that is not without difficulties, especially in a place like Afghanistan. However, there is a possible scientific solution. It turns out that Tasmania, of all places, is an important opium poppy producer, and researchers at “Tasmanian Alkaloids recognised that there was a possibility of breeding a poppy variety in which the biosynthetic pathway stopped at thebaine instead of going on to produce morphine.” That would make it ok for therapeutic opiate production but useless for the illicit drug trade. You can read all about it here. There’s a paper on poppy transformation here and one on poppy genetic diversity here.
