Abstract
The present investigations on 10 hybrids and one check variety of Gladiolus hybridus
were carried out to know their performance and to findout their suitability for cut flower
production under transitional tract of Karnataka.
There were significant variations for all the characters among the genotypes studied.
Dharwad-10, Dharwad-1, Dharwad-3, Dharwad-7 and Dharwad-5 showed superior
performance over other hybrids and also check variety with respect to number of days taken
for first floret to open, spike length, number of florets per spike, rachis length and dormancy
period etc.
Spike characters are important with regard to cut flower production in gladiolus
especially when we consider quality. The hybrids under study have shown significant
differences with respect to spike length, spike girth, rachis length and weight of the spike.
Spike length showed a significant positive correlation with average weight of corm
(planted), plant height, girth of spike, weight of the spike, rachis length, number of florets per
spike and number of cormels per plant at genotypic level.
The highest direct effect on spike length was observed in case of number of days
taken for first floret to open, number of florets per spike average weight of corm planted,
length of the rachis and number of cormels per plant.
The present study revealed that the improvement in gladiolus for qualitative and
quantitative characters can be done by direct selection for desired characters like average
weight of corm (planted), number of florets per spike, marketable spike per plant, number of
cormels per plant and number of days taken for first floret to open.
