GENETIC VARIABILITY STUDIES IN GLADIOLUS (GLADIOLUS HYBRIDUS HORT.) UNDER SUB HUMID CONDITION OF RAJASTHAN
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
Twelve genotypes African Star, Arti, Darshan, Friendship, Hunting Song, Legend, Pusa Srijana, Pusa Kiran, Snow Princess, Sunayana, Trader Horn and Urmi of gladiolus were evaluated to determine genetic variability, heritability, genetic advance and genetic gain for twenty seven contributing characters. The gladiolus genotypes were procured from the Indian Agricultural Research Institute, New Delhi. The high value of PCV along with GCV indicated that there is more variability in the characters like, days to 50% sprouting, sprouts per corm, spikes diameter, duration of flowering, number of side spikes per plant, number of corms per plant, size index of corm, number of florets remaining open at a time and number of florets remaining unopened. High heritability with high values of genetic advance was observed for weight of cormels per plant, number of cormels per plant, rachis length, spike length, weight of corms and number of spikes per plot.
