Five new forms of seeds of Basmati rice, developed by a gaggle of scientists led by the Indian Agriculture Research Institute (IARI) Director Dr. Ashok Kumar Singh in 2020 and 2021, are all set to convey revolutionary adjustments in the way in which Basmati rice is cultivated within the nation.
Three of the 5 varieties can resist two widespread illnesses of paddy (one bacterial and one fungal). The different two varieties can save 35% of water as the tactic of Direct Sowing of Rice (DSR) can be utilized to lift them. These two seeds are proof against herbicides too, serving to the farmers management weeds extra effectively.
In the following three years, the entire 5 seeds may have the mixed qualities of illness and herbicide resistance, says Dr. Singh.
“This is a landmark achievement. We started the research in 2008. This is 100% indigenous revolution using indigenous breeding programmes,” Dr. Singh tells The Hindu. “This will help in increasing farmers’ income by reducing the cost of cultivation, by improving production and by realising price of their labour and input cost. The cost of cultivation will be reduced. It will reduce the use of pesticides and water. If the production is free from residue, it will get better prices,” he defined.
Export in thoughts
India is thought for its Basmati rice, with seven States — Jammu and Kashmir, Himachal Pradesh, Punjab, Haryana, Delhi, Uttar Pradesh and Uttarakhand — earmarked for geographical indication. Basmati, recognized for its mouthfeel, aroma, size of the grain when cooked and style, has a market overseas and brings about ₹30,000 crore international change yearly. While 75% of the export is to West Asian nations, European Union nations additionally import Indian Basmati. However, not too long ago, the export to EU nations confronted sure hurdles as a result of improve within the pesticide residue ranges within the rice from India.
Dr. Singh says that over a time period, as the realm of cultivation elevated, conventional varieties develop into inclined to 2 main illnesses — bacterial leaf blight (BLB) and blast (leaf and collar) illnesses attributable to the fungus Magnaporthe oryzae. Pesticides and fungicides used in opposition to these illnesses elevated the residue ranges permitted in developed nations.
“Achieving the permitted levels is very difficult if we are using pesticides for controlling pests. The only way was that we bring in genetic resistance so that we do not have to spray pesticides and fungicides. So, from Pusa Basmati 1121, we developed Pusa Basmati 1885; from Pusa Basmati 1509, we developed Pusa Basmati 1847; Pusa Basmati 1401 was improved to develop Pusa Basmati 1886. All these varieties have two genes to resist BLB and two genes to resist blast disease. Farmers need not use pesticides and it will decrease the cost of farming by ₹3,000 per acre. Because of effective disease control, production will increase and most importantly, there is no question of pesticide residue and our consignments will not be rejected,” Dr. Singh says.
The IARI offered one kilogram every to about 10,000 farmers in these seven States in 2021. “They had grown these crops during this kharif season. In the last week of September, I travelled 1,500 kilometres to see for myself how the crop is doing and to hear the feedback from farmers. I stayed at the residences of farmers. There is phenomenal response for these varieties. I am hoping that from next year, these varieties will change the scenario of Basmati cultivation and it will directly help in terms of addressing the problem of pesticides residue,” Dr. Singh says, sharing hopes of an elevated protection space within the subsequent crop yr. “I have asked farmers to keep this year’s produce for next year as seeds,” he provides.
The IARI developed Pusa Basmati 1979 and Pusa Basmati 1985 as herbicide tolerant rice by enhancing the Pusa Basmati 1121 and Pusa Basmati 1509, respectively. The conventional manner of paddy cultivation relied on transplanting the vegetation right into a water-filled discipline halfway by way of the cycle. “Around 3,000 litres of water is required for one kilogram of Basmati rice. This has impacted the groundwater table of States like Punjab and Haryana. We have to change the practice of cultivating transplanted variety of paddy to direct sowing of rice (DSR). Water saving is 35% in DSR and the requirement will be 2,000 litres of water for a kilogram of rice. The second advantage is that the green house gas emission is reduced by 35% as water is not stagnating in this process. Labour cost of transplantation, which is about ₹3,000, is also saved. Overall, saving will be at least ₹4,000 per acre. Just do the sowing in the field and let the crop grow there,” he says.
However, one of many main drawback within the DSR is weeds. Without the water appearing as a herbicide, the DSR methodology permits for lot of weeds to crop up within the discipline. “So, we transferred a gene that is resistant to a herbicide. So, when farmers spray herbicide, weeds will be killed, not paddy,” he says.
Process in place
The first course of in growing these two varieties was to do a mutation breeding utilizing a chemical referred to as Ethyl Methanesulfonate (EMS) to establish a variant within the plant that survives the appliance of herbicide.
“Last year, we released the seed to farmers on an experimental process. This is a non-genetically modified herbicide-tolerant seed. GM is a good technology but many markets such as European Union doesn’t accept GM rice. We get about ₹8,000 crore from exporting Basmati rice to EU countries. A minor step is incomplete, which is making an application to the Central Insecticide Board’s registration committee to allow us to expand its label claim to this variety. The process may take some time. We have to submit dossiers about the efficacy of the seed. The data has been submitted. We hope that all formalities will be cleared by next crop season. This year, we have done trialling under control. Everything is fine. It provides effective weed control. The cooking quality is also excellent. There is no residue of any kind of herbicides,” Dr. Singh says.
