Purpose of Description

ICGV 87187 (ICGS 37), tested under the name of ICGS 37 in the All India Coordinated Research Project on Oilseeds (AICORPO) trials, was released in 1990 by the Central Sub-Committee on Crop Standards, Notification and Release of Varieties, Department of Agriculture and Cooperation, Ministry of Agriculture, Government of India, for cultivation in the summer groundnut zone II consisting of Gujarat, Madhya Pradesh, and northern Maharashtra in India. It is also registered with the National Seed Registration Department, National Agricultural Research Center, Islamabad, Pakistan. It forms a component line together with another ICRISAT groundnut selection, ICGV 87128 (ICGS 44), of a recently released groundnut variety BARD-699 in Pakistan.

Origin and Development

ICGV 87187 (ICGS 37) was bred and developed at ICRISAT Center. It derives its origin from a single-plant selection made in a natural hybrid population of an Indian cultivar Robut 33-1 (now known as Kadiri 3) in 1977/78. This plant was grown in progeny rows for two seasons following the pedigree method and later advanced to uniformity by the bulk pedigree method. Its pedigree is (Robut 33-l)-l-l-B1-B1-B1-B1- B1. Kadiri 3 is an early-maturing virginia-type variety. The other parent of ICGV 87187 is unknown, but may have been a spanish-type variety since the natural hybrids were identified by the presence of flowers on the main axis, and the sequentially branched Spanish forms were subsequently observed in the segregating generations.
