dc.description.abstractABSTRACT The present investigation entitled “Variation studies in Ulmus villosa Brandis” was carried out at the experimental field of Department of Tree Improvement and Genetic Resources during 2010- 12. Seeds were collected from five mother trees each at six seed sources and progenies were raised to study the extent and pattern of variation with respect to growth and biomass characters. However, the wood samples were collected from selected trees for studying wood characters. Site S4 (Jagoti) exhibited outstanding performance for the growth and biomass characters of progenies followed by S1 (Jadh) and S5 (Katouch), whereas S3 (Jhidi) showed the lowest values for these characters. Site S6 (Andhra) trees exhibited outstanding performance for wood characters followed by S4 (Jagoti) trees. High heritability with moderate genetic gain was observed for collar diameter followed by plant height and petiole length among growth and biomass characters and high heritability with moderate genetic gain was recorded in wood density among wood characters. Highly significant and positive genotypic and significant phenotypic correlation were observed for height and diameter, fresh shoot weight and fresh root weight and dry shoot weight and dry root weight. RAPD pattern was studied using 10 primers all of which showed amplification. Fifty seven scorable bands were identified in the range size of 147.10 bp-2901.97 bp. The dendrogram generated using RAPD markers showed Jugahan-T3 as most divergent. Maximum similarity of 70 percent was observed between Jagoti-T3 and Jagoti-T2.en_US
