Abstract: Thirty plus trees have been selected from dominant rosewood growing areas in Kerala based on growth attributes like tree height, girth at breast height, clean bole height and seed yield. Seeds were collected from these identified genetic resources and incorporated in the evaluation program. The thirty plus trees differed significantly due to various seed attributes coupled with the germination traits. Considering all the seed and germination attributes, the superiority of seven progenies viz., KLMYKUT 1, KLNLKAR 2, KLNLKAR 4, KLNMNEL 3, KLNMNEL 6, KLTMPLO 5 and KLTRMAC 6 were evidenced. The variability studies on growth attributes indicated that the genotypic co-efficient of variation was higher than the phenotypic co-efficient of variation for most of the characters and expressed that these characters are strongly under genetic control.
