Determination of genetic diversity in Chenopodium spp.

Published on

Field experiments were conducted for two successive
seasons to assess the genetic diversity in 44 germplasm
lines of
Chenopodium. Eleven agronomic traits were
analyzed for cluster and principal component (PC) analysis.
The first 4 PCs contributed 88.10
% of the variability
present among the lines. Three characters contributed
positively to all the 4 components. The first principal
component (PC
1) had plant height, inflorescence length
and stem diameter as the variables with largest coefficients.
The germplasm was categorized in 4 clusters following
Ward's method.
A wide range of diversity for most of the
traits were observed that would enable breeders to identify
lines with suitable traits to be used in hybridization
programmes for broadening the genetic base.
