Genetic Diversity of Global Finger Millet Composite Collection Based on Qualitative Traits and Biological Races

摘要

The global composite collection of finger millet (1000 accessions) was evaluated to study the variability for six qualitative traits under field condition in three environments. Wider variation for all the qualitative traits was observed and racial wise wild races africana and spontanea had more diversity for all qualitative traits. However the cultivated races showed difference in inflorescence shape. Most of the cultivated race accessions were predominated by the erect plant habit, green pigmented,top curved, low glume prominence and light brown seed colour. Genetic diversity in these traits can be used by broadening gene pool through national and international sources, wide hybridization, mutation or other genetic modification.
