Finger millet [Eleusine coracana (L.) Gaertn.], among small millets, is the most important food crop in some parts of Asia and Africa. The grains are a rich source of protein, fi ber, minerals, and vitamins. A core collection of 622 accessions was developed. The aim of this study was to develop a mini-core collection using multilocational evaluation data of the core collection. Six hundred and twenty-two accessions together with six controls (four common and two location-specifi c) were evaluated for 20 morphological descriptors at fi ve agroecologically diverse locations in India during the 2008 rainy season. The experiment was conducted in α design with two replications at Patancheru and in augmented design with one of the six controls repeated after every nine-test entry at other locations. The hierarchical cluster analysis of data using phenotypic distances resulted in 40 clusters. From each cluster, ~10% or a minimum of 1 accession was selected to form a mini-core, which was comprised of 80 accessions. The comparison of means, variances, frequency distribution, Shannon-Weaver diversity index (H`), and phenotypic correlations revealed that the mini-core captured the entire diversity of the core collection. This mini-core collection is an ideal pool of diverse germplasm for identifying new sources of variation and enhancing the genetic potential of fi nger millet.

Foxtail millet is an important staple crop in some parts of China, India and Japan, and a potential bioenergy source. The grains are rich source of protein, fiber, minerals and vitamins. We had earlier reported the development of a core collection (155 accessions) of foxtail millet. This study was initiated to identify trait-specific germplasm for agronomic and nutritional traits, and to develop a mini core through multilocational evaluation of the foxtail millet core collection. One hundred and fifty-five accessions together with five controls (four common and one location-specific control) were evaluated for 21 descriptors at five agro-ecologically diverse locations in India during the 2008 rainy season. The experiment was conducted in an alpha design with three replications at Patancheru, and in an augmented design with one of the five controls repeated after every nine-test entries at other locations. A number of diverse germplasm accessions with agronomically (earliness and high grain yield) and nutritionally (high seed protein, calcium, iron and zinc) superior traits were identified for use in foxtail millet breeding. The hierarchical cluster analysis of data using phenotypic distances resulted in 25 clusters, from each cluster, ∼10% or a minimum of one accession was selected to form a mini core, which comprised of 35 accessions. The comparison of mean, variance, frequency distribution, diversity (H') and phenotypic correlations revealed that the mini core indeed captured adequate variability from the core collection. This mini core collection is an ideal pool of diverse germplasm for studying population structure and diversity, and identifying new sources of variation for use in breeding and genomics studies in foxtail millet.

A study was conducted for two years during 2014-15 and 2015-16 involving 30 and 15 farmers at Tumkur and Ramanagara districts, respectively. The improved finger millet variety KMR-301 and KMR-204 were used to demonstrate the improved production technology on finger millet in the farmer's field. The data revealed that during 2014 by the introduction of new technology the grain yield was increased by 36 per cent over farmers practice and during 2015, at Ramanagara district the yield improvement was to the tune of 16 per cent.
