Present investigation was carried out using15 genotypes of groundnut. The crop was sown during Kharif season and ten morphological characters were studied and further we isolated DNA of all, did random amplification using 15 RAPD primer. ANOVA revealed significant mean squares due to genotypes for all the characters thereby indicating substantial amount of genetic variability among the genotypes. Cluster analysis using Ward's method showed sufficient genetic distance among the gentypes. Purity of isolated DNA through CTAB method was analyzed through spectrophotometer found fairly good. Total...

The present book discusses the isolation and genetic diversity analysis of Rhizobia from chickpea (Cicer arietinum L.). Indiscriminate use of synthetic fertilizers has led to contamination of the soil, polluted water basins, destroyed micro-organisms & friendly insects, making the crop more prone to diseases and most importantly reduced soil fertility. Bacteria of family Rhizobiaceae are symbiotic and effectively convert atmospheric nitrogen which is utilized by the host and internationally been accepted as an alternative source of chemical fertilizer. The long term use of bio-fertilizers is...
