Abstract

The present experiment was conducted to portray the core collection of germplasm accessions; with special reference to trait specific classification, screening for blast disease and cross combination studies in finger millet (Eleusine coracana L.), during Kharif 2020-21 at Research cum Instructional Farm, S G College of Agriculture and Research Station, Jagdalpur, IGKV, Raipur, Chhattisgarh, India. Among the test accessions, characterization was done in respect to major yield related parameters and trait specific genotypes were short listed for future as donor parents for introgressive breeding for instance, genotypes GEC453, GEC53, GEC127I, C0477591, IC0477496, GEC5 and IC0477678 for high tillering capacity; GEC222, GEC322, GEC11, GEC92, IC0477556-X, GEC55, IC0476676, GEC79, IC0477304, IC0477620 for high numbers of finger per ear; GEC371, IC0476669-X, GEC223, GEC394, IC0477678 for finger length; and IC0477650, GEC69, IC0476495, GEC55, IC0476299, GEC254, GEC347, GEC470, IC0477507, GEC122 for test weight. In screening for all three phenotypic variants of blast disease GEC92, IC0477317, IC0477406, GEC147, GEC79 (for leaf blast) IC0477650, GEC41, GEC322 (For neck blast) and IC0476838, GEC132, GEC352, GEC106 (against finger blast) exhibited resistance, which need to verified in controlled environments. In cross compatibility studies with some specific parents F1 had been harvested and selection will be made in segregating generations. Summarily, after achieving saturation in artificial selection and recombination breeding, research mode must be shifted towards widening of genetic base, traits specific breeding and development of variable need based cultivars with respect of quality and end produce to meet the growing population demands, raising insect pest pressure and changing climatic scenario.
