NATURE AND PATTERN OF GENETIC DIVERGENCE OF SUGAR YIELD AND ITS COMPONENTS IN THE PROGENIES OF SACCHARUM BARBERI

Published on

Thirty hybrid clones involving Saccharum barberi (B), S. officinarum (0) and Co
hybrids (H) were evaluated alongwith their seven parents to study the nature and
pattern of genetic divergence. Data on eleven characters of sugar yield were recorded
and subjected to multivariate D2 analysis. The clones were grouped in 15 clusters.
The clustering pattern showed that grouping of progeny clones was independent
of parent cross combinations, i.e. progenies of a cross and their parents were grouped
in different clusters. Hybridization among clones from diverse clusters may help in
isolating progenies with higher sugar yield and its traits.
 

Keywords: Saccharum barberi, S. officianarum, genetic divergence, multivariate analysis, sugar yield.
