USE OF SEMI·GRAPffiCAI. TECHNIQUE FOR CLASSIFICATION OF ISABGOL GERMPLASM

Abstract

Sixty-one accessions of Isabgol (Plantago ovata Forsk.) including five
exotic ones received through the National Bureau ofPlant Genetic Resources,
NewDelhi were classified basedon semi-graphical technique. Geneticdiversity
proved to be more important than geographical diversity. On the basis ofindex
score values and ray patterns of different traits, promising genotypes which
could be utilized in heterosis breeding programme included P 96, P 33, HI 8,
HI 4, S 11, PI and MS for high seed yield; HI 5, Mutant S, EC 41181-37 T
(high-yielding, high number of spikes group) and G 1 (medium-yielding
medium number ofspikes group) for husk percentage. LYHS (low yield high
number ofspikes), HYLS (high yield, low number ofspikes, and HYMS (high
yield, medium number ofspikes) groups did not cantain any genotype.
