I am certain you lot stimulate got heard it i time to a greater extent than as well as again. Agricultural scientists are developing crop varieties that are resistant to drought as well as besides resistant to floods. These varieties are beingness developed yesteryear transferring a cistron from such naturally available varieties into the high-yielding varieties, as well as the scientists are giving an impression every bit if they stimulate got genuinely invented these drought-resistant or flood-resistant varieties.
I stimulate got ever wondered why can’t these scientists search, conserve as well as save the naturally ocurring crop varieties that are either resistant to floods or drought or for that thing tin move live grown successfully inward saline soils. Once you lot stimulate got identified such varieties, it is non hard to select the promising ones as well as promote them inward the environs to which they belong. For instance, some of my colleagues stimulate got already identified to a greater extent than than a dozen rice varieties that are suitable for the inundation prone regions of the northeast. Similarly, at that topographic point are numerable rice varieties available that are resistant to drought, as well as I know a expose of groups/farmers who stimulate got such varieties inward the traditional cistron banks or inward in situ conservation.
After Tsunami had struck the coastal belt of Tamil Nadu, scientists were amazed at the functioning of at to the lowest degree 2 rice varieties that resisted the intrusion of tabular array salt water.
Deep H2O rice, for instance, was an surface area of specialisation at the International Rice Research Institute, Los Banos, inward the Philippines. I recall how much importance IRRI gave to deep H2O rice (and besides upland rice) inward the 1980s as well as 1990s. But instead of conserving as well as developing the traditional deep H2O rices, I am amazed at the shift inward IRRI inquiry focus on transferring genes from these varieties into the HYVs. This alone shows that scientists stimulate got trivial to produce present as well as are looking for such unwanted inquiry focus so every bit to justify the research investment.
On such discovery is the Sub1 cistron from the Indian rice accession FR13A. This cistron has been transferred into some of the pop rice varieties non alone inward Republic of Republic of India but besides inward other Asian countries. The National Seed Industry Council of the Philippines has approved its ‘first flood-resistant variety’ (see the report: http://greenbio.checkbiotech.org/news/first_flood_tolerant_rice_variety_approved_rp_use).
In India, the cistron has been transferred into Swarna, a pop HYV. Scientists claim that Swarna tin move live on 10 days of consummate submergence inward H2O at the vegetative stage.
I wonder whether scientists stimulate got ever seen traditional flood-resistant varieties inward the Sunderbans Delta region? Claims almost production potential notwithstanding, these varieties stimulate got fared good over centuries. As far every bit the production claims are concerned, much of it is simply an exaggeration. I challenge agricultural scientists to demonstrate me when were they able to accomplish the production figures they claim. None of the universities/agriculture institutes stimulate got been able to replicate the production potential claims. The argue is obvious. These figures are based on a pocket-sized exam plot, as well as the crop harvested is so transpolated to a hectare. You larn production figures which are non based on actual yields inward bigger fields.
But non all is lost. There are NGOs as well as farmers inward Republic of Republic of India who are trying to save the ancient wisdom, as well as conserving these splendid rice varieties that nature has provided. As a land nosotros need to appreciate as well as applaud such efforts. I am so delighted to read an article inward today’s edition of Deccan Herald on deep H2O rice, as well as the credit must larn to the author Anitha Reddy. Not many journalists as well as writers present are keen to write on such topics, as well as I therefore extend my gratitude to Anitha Reddy for bringing this to populace attention. Thank you lot i time again.
Paddy that survives the flood
In an era when yield functioning of crops is the alone component taken into consideration, Varada basin farmers are striving to conserve strains that they stimulate got inherited as well as retained over 4 decades, writes Anitha Reddy
Farmers inward the Varada river belt stimulate got adapted to the fury of the river that flows inward Sagar, Soraba as well as Sirsi taluks. The rivulet, which takes nativity at Sagar, flows through Sirsi as well as Soraba for almost eleven kms earlier joining the Tungabhadra. During its brusque journey, the Varada wreaks havoc as well as destroys thousands of acres of paddy fields when continuous pelting swells the waterways. This puts at gamble at to the lowest degree 30,000 people inward 25 villages depending on it.
Flooding is an annual phenomenon here. However, it does non hateful that farmers produce non grow anything during the flood. They possess a unique wealth that enables them to grow paddy fifty-fifty inward flooded conditions, as well as the varieties of rice tin move subsist deep standing H2O for a long period.
Now, piece scientists are pondering over developing submergence-tolerant varieties of paddy, farmers roughly Sirsi, Sagar as well as Soraba taluks are much ahead of them when it comes to cultivating flood-resistant varieties.
“Flooding is a mutual phenomenon here. Every year, at that topographic point is flooding as well as farmers stimulate got adapted to it. At a fourth dimension when agriculture yesteryear itself is considered a tough occupation, farmers stimulate got establish a mode out yesteryear cultivating some of these rare varieties,” says Raghunandana Bhat, a resident of Banavasi.
Over centuries, farmers inward the percentage stimulate got carefully developed as well as preserved varieties that tin move live on when their lifeline, the river Varada, invades their fields. These flood-resistant varieties agree a meaning house inward the biodiversity of the area.
The Varada basin is dwelling to deepwater rice varieties similar Nereguli, Karibatha, Sannavaalya, Karijaddu, Kani Somasale, Jenugoodu, Nettibatha, Kari kantaka, Edi kuni, as well as Karekal Dadiga.
The most pop amid these varieties is Nereguli, which has proved to live the best deepwater variety for years. It is liked for its vigour, gustatory modality as well as wellness quotient. This variety is organically grown using traditional methods as well as is highly nutritious as well as inward keen demand, inward Kerala as well as Goa.
