Genetic variability studies in gladiolus (Gladiolus hybridus Hort.)
Genetic variability studies in gladiolus was carried out among 22 diverse genotypes for 20 characters at Research Farm (Floriculture), Jammu for two years during 2010-2011. The variables under study were American Beauty, Appache, Bonos Memory, Black Beauty, Congosong, Canidman, Day Dream, Enchantress, Friendship, Great Britan, Her Majesty, Jester Gold, Lucky Number, Oscar, Pb. Morning, Red Beauty, Trader Horn, White Friendship, White Prosperity, Wine & Roses, Pacifica, Wind Song, Congo Song and Black Beauty. The PCV were higher than GCV for all the characters studied, indicating thereby high degree of environmental influence. Higher GCV and PCV estimates were found for number of cormels per plant and average weight of cormels per plant. Hertiablity estimates were high (›80%) for days to 50% heading, days to first floret opening, days to last floret opening. Whereas, propagation coefficient, number of cormels per plant showed moderate to high heritability along with genetic advance showing additive gene effects.
