• Maharashtra Association for the Cultivation of Science (MACS).
• New wheat variety helps farmer in a karanjkhop village in Koregoan (satara) in Maharashtra double their yield.
- The newly developed common wheat or bread wheat also called high yielding Aestivum, Matures in 110 days and is resistance to most races of leaf and stem rust.
This wheat variety is developed by scientists from Agharkar Research Institute (ARI), an autonomous institute of government of India
This institute comes under the ministry of science and Technology
The farmers of the village in Koregoan tehsil of satara district in Maharashtra are now getting a yield of 40–60 quintals per hectare with the new variety as against previous one average yield ranging 25–30 quintal per hectare when they cultivate lko1, HD2189 and other varieties of wheat.
What High Yield varieties requires more as normal varieties
• They require more water
• They require more fertilizers as compared to the normal varieties of crops.
• They require frequent weeding
• Continuous use of pesticides
• Sometimes the high yield crops may be more susceptible to diseases.
The new variety of MACS 6478 which is medium sized developed grain of wheat contain
44 ppm zinc
43 ppm iron
Higher than previous other cultivated varieties.
Maharashtra State seed agency for seed multiplication, Mahabeej is carrying out certified seed production of MACS 6478 for use by farmers.
Other crops that are developed and in news during year 2020
Agharkar Research Institute (ARI) Pune, itself earlier in 2020 developed a bio-fortified wheat variety MACS 4028.
The wheat variety developed by the ARI scientists group on Wheat improvement, shown high protein content of about 14.7%, better nutritional quality having zinc 40.3 ppm, and iron content of 40.3ppm and 46.1ppm respectively, good milling quality and overall acceptability.
MACS 4028 are a semi-dwarf variety, which matures in 102 days and has shown the superior and stable yielding ability of 19.3 quintals per hectare. It is resistant to stem rust, leaf rust, foliar aphids, root aphids, and brown wheat mite.
Recently farmers from Golghat district in Assam cultivated new flood resistance paddy varieties to shift from the traditional ones.
The varieties called Ranjit Sub 1 and Bahadur Sub 1.
. Pokkali Variety of Rice
Farmers in west Bengal started growing Pokkali variety of rice as sever seawater incursion happened into paddy fields in the Sundarbans (owing to cyclone Amphan). Vyttila-11 varieties of Pokkali seedlings were bought from Kerala.
The Pokkali variety of rice is known for its saltwater resistance and is grown in Alappuzha, Ernakulam and Trissur districts of Kerala
Sahyadri Megha is a red variety of paddy resistance to blast diseases
It was developed under the hybridization breeding method by cross- breeding ‘Jyoti’ variety with Akkalu.
The Jyoti variety in Karnataka became vulnerable to blast diseases and other infestations. There was a surge in demand by consumers in urban areas for rice which is rich in fiber and protein.
The university of Agriculture and Horticulture science (UAHS) of Shivamogga developed this new red variety of paddy called Sahyadri Megha having high proteins content..
Qualities of Sahyadri Megha
• The variety is resistance to blast ( a fungal diseases) and rich in nutrients.
• The proteins content in it is 12.48% , higher than any red rice variety grown.
• The yield per hectare from Sahyadri Megha is around 65 Quintals, substantially higher than other red paddy varieties.
• It is medium term paddy that can be grown when there is a decay in onset of monsoon.
- It can be harvested after 120 days of sowing.
• The new rice variety Muktoshri (IET 21845) was developed jointly by the Rice Research Station at chinsurah coming under west Bengal Agriculture Department and the national botanical research institute, Lucknow.
• Long term exposure to arsenic from drinking water and flood can cause cancer and skin diseases. It can also been associated with cardiovascular diseases and sugar.
- Contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health from arsenic.
• It is one of the most crippling issues in the drinking water scenario of India.
• Several studies have shown that arsenic from ground water and the soil can enter the food chain through paddy.
• According to the latest report of the central ground water board (CGWB), 21 States across the country have pockets with arsenic levels higher than the Bureau of Indian standards (BIS) with marginal limit of 0.01 milligram per liter (mg/l).
WHO — Arsenic is one of WHO’s 10 chemical of major public health concern.
WHO publishes a guidelines value of arsenic in guidelines for drinking- water quality. The guidelines are intended for use as the basis for regulation and standard setting worldwide
This were the list of some varieties of crop that was developed by various institute around the India of which some were high-yielding varieties while some of them were bio-fortified ones.
In next article we will discuss more about the specific list of bio-fortified crops introduced in 2020.
