GIRNAR 1 nlm - A NEW NARROW LEAF MUTANT OFGROUNDNUT

Abstract

In groundnut (Arachis hypogaea L.) available variability for simple inheritance in the germplasm pool is very much limited. Induced mutations are considered to be an alternative/supplement to hybridization for generating variability in groundnut, particularly canopy development and pod number, without altering the agronomic traits of the cultivars under study [1, 2]. Such diversified genetic variability could be valuable as useful germplasm. By the treatment with mutagens, recessive mutations are often realized in M2 and subsequent generations [3]. Certain alkylating agents such as diethyl sulphonate (DES) and ethyl methane sulphonate (EMS) have often been used for producing mutants in groundnut [2]. We are reporting a new narrow leaf mutant of groundnut developed through chemical mutagenesis.
