GENETIC DIVERGENCE IN LINSEED GERMPLASM (Pages : 13 - 20)

Genetic diversity study on 81 linseed genotypes were conducted at two locations, Sinana and Robe in the highlands of Bale, in order to assess the nature and magnitude of genetic diversity for yield, yield related traits and oil content. The D2 analysis allowed the 81 genotypes of linseed to be identified into ten distinctive clusters. The analysis indicated that genetic diversity was not necessarily related with geographic diversity. The observation suggested that accessions from different agro ecological zones fall in the same cluster and, thus, indicated their closeness. On the other hand, accessions from the same agro ecology were distributed to different clusters. Therefore, accessions from different regions might have the same genetic background and those from the same origin might have different genetic background. Maximum distance was observed between cluster I and IV (D2=762.3) at Sinana and between cluster I and III (880.65) at Robe whereas the minimum distance was between cluster VIII and IX (D2 = 17.4) at Sinana and between cluster IX and X (D2 = 20.837) at Robe. However, the analysis suggested that here is considerable diversity among the germplasm accessions included in the present study. There is good scope to bring about improvement through hybridization and selection by crossing accessions from different clusters.Download
