26 September 2022, New Delhi: For research and development programs on soybean, new varieties are being developed continuously for the last few years by the ICAR- Indian Institute of Soybean Research, Indore. In the successive efforts made by ICAR-IISR, the Institute has developed three varieties of soybean i.e NRC 157, NRC 131, and NRC 136 which have been approved by the Government of Madhya Pradesh.

It has an average yield of 16.5 qt./ha. and is also moderately resistant to diseases like Alternaria leaf spots, bacterial pustules, and target leaf spots. Field trials in the institute have found NRC 157 suitable for delayed planting (up to 20th july) with minimum yield losses. Whereas talking about another variety developed by him, NRC 131 (IS131), he highlighted that it is a medium duration variety of 93 days, with an average yield of 15 qt./ha. This variety is moderately resistant to diseases like charcoal rot and target leaf spots.
Along with these two varieties, NRC 136 (IS 136) which has already notified for cultivation in eastern region of the country, has also been released for cultivation in Madhya Pradesh this year. Dr Gyanesh Kumar Satpute, the Breeder of this variety and the Principal Scientist of the institute, said that this variety matures in 105 days with an average yield of 17 qt./ha., NRC 136 is moderately resistant to MYMV (Moongbean Yellow Mosaic Virus) and is India’s first drought-tolerant variety.
