STUDY OF GENETIC DIVERSITY IN HIGH BIOMASS SORGHUM IN MARGINAL LANDS AS LIGNOCELLULOSIC FEED STOCK FOR BIOETHONOL PRODUCTION
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 57
Abstract
Forty genotypes of high-biomass sorghum lines identified in the US-Indo Consortium for Development of Sustainable Advanced Lignocellulogic Biofuel Systems (JCERDC) project on characterizing high-biomass sorghum were evaluated at four locations in marginal lands of Madhya Pradesh to know the nature and magnitude of genetic diversity for biomass yield. The genotypes were grouped into four clusters. The cluster II and III were the largest cluster with fifteen genotypes each. Cluster I was represented by genotype IS16529 showing mean biomass yield of 44.3 t/ha over four locations with highest yield of 61.1t/ha at Dewas location. Cluster II was represented by genotype IS23101 showing mean biomass yield of 43.4t/ha with highest yield of 63.3 t/ha at Gwalior location. Cluster III was represented by genotype CMS x S630 showing mean biomass yield of 25.0 t/ha with highest biomass yield of 40.0 t/ha at Gwalior location. Cluster IV was represented by genotype GIRD39 showing mean biomass yield of 35.9 t/ha with highest yield of 44.6 t/ha at Gwalior location. Study found that considerable genetic diversity exist in the study material. Whereas Gwalior was the ideal location for all the genotypes as all three high yielder i.e. IS23101, CMS X S630 and GIRD39 in cluster I, II and III respectively were out yielded at Gwalior location.
