| dc.description.abstract | The present investigation entitled “Line x Tester analysis for combining ability in Gladiolus (Gladiolus hypridus)” was taken up to evaluate some of the available germplasm of gladiolus for their future utilization in crop improvement programme. The line x tester analysis for combining ability was done with ten parents and twenty one crosses alone for different characts and percent of contribution by male and female parents for each character had been computed. The parents and crosses differed significantly for almost all the characters. The mean value of the crosses was at par with their respective parental mean in almost all the characters. The genotypic and phenotypic coefficient of variation was higher for character for the no. of florets open at a time, spike length and vase life. Large no. of crosses was found to give significant heterosis over mid parent and better parent. Sunset Sky x Eighth Wonder (23.58) for spike length (26.68), diameter of floret (20.34), number of floret open at a time (11.43) and vase life (23.61) was recorded maximum positive heterosis over better parent. Urmil x Candyman Showed maximum positive heterosis for number of floret per spike. Punjab Dawn was the best combiner for earliness for spike emergence (-17.49) and flower bud initiation. Sunset Sky recorded 2.14 gca effect which was the best general combiner for number of florest per spike. Summer Sunshine recorded 1.62 gca effect. The best combiner for diameter of floret was Summer Pearl with 2.59 gca effect. Among the lines Urmil -2.19 gca effects had recorded highest positive gca effect for vase life. In correlation study days taken for spike emergence, bud initiation, no. of floret per spike was found to be positively and significantly correlated with the days taken for the 1st floret to open, no. of floret open at a time, spike length and vase life. | en_US |
