GENETIC VARIABILITY AND CHARACTER ASSOCIATION IN INTERSPECIFIC HYBRIDS OF SUGARCANE

Published on

In an interspecific hybrid population of 46 clones derived from crosses of various
Saccharum spp., number of millable canes, sugar yield and single cane weight recorded
high genotypic coefficient of variation. High heritability coupled with high genetic
advance were recorded for CCS, sucrose content, and number of millable canes. Cane yield
recorded low heritability and low genetic advance. Sucrose, brix, CCS and sugar yield were
positively interrelated. Cane yield did not have significant positive association with any of
the yield attributes except number of millable canes. The hybrids derived from the crosses
involving commercial hybrids with S. robustum or S. barber; were superior to other hybrids.
 

Keywords: Saccharum, variability, heritability, correlation, interspecific hybrids.
