Phenotype Based Selection in Kodo Millet (Paspalum Scrobiculatum L.) to Identify Elite Accessions

Abstract

Background: Kodo millet (Paspalum scrobiculatum L) is an annual hardy crop grown in India from Kerala and Tamil Nadu in the south, to Rajasthan, Uttar Pradesh, and West Bengal in the north. It is known to have high drought tolerance and, for its potential to sustain in marginally less fertile soil. The grain has high nutritional properties thus possess medicinal values. Owing to multiple utility factors and sustainable growth rate amidst climate change, makes it an ideal crop for cultivation. In the present study accessions of Kodo millet ((Paspalum scrobiculatum L) from twelve different geographical regions of India were evaluated for quantitative and qualitative traits to determine its growth conditions under varied climatic conditions. Methods: Total of 96 indigenous germplasm were collected across the country and were sown in a breeding farm to grow selectively healthy crops in a randomized block design manner during kharif 2012 and 2013. Observations of quantitative traits were recorded on five arbitrarily selected plants in each replication for different physiological traits. Results: The statistical data revealed significant differences among all the studied accessions. Mainly IC482729 and IC404789 from Tamil Nadu had high biomass, straw yield, and yield per plant. IC396004 from Chhattisgarh showed advantageous performance in earliness with medium plant height. Therefore, the present findings helped in identifying elite germplasm accessions and could be effectively used in the Kodo millet enhancement program.
