COMBINING ABILITY IN ROSELLE (HIBISCUS SABDARIFFA L. VAR. ALTISSIMA)

Published on

Combining ability studies in a 10 x 10 F2 diallel set of roselle indicated that mean sum of
squares due to gca as well as sca were significant for six characters, while gca : sca ratio
more than unity suggested the prevalence of additive gene effects. The genotype AMY 2
was the best general combiner for economic attributes while the crosses AR 105 x
AMY 2 and AMV 2 x CP 510 were the best specific cross combinations.
 

Keywords: Combining ability, gca, sea.
