QUANTITATIVE EVALUATION OF INDUCED MACROMUTANTS IN FENNEL (FOENICULUM VULGARE MILL.)

Rita Paul, Animesh Kumar Datta

Open full text 3 citations

Abstract

Macromutants namely, thick stem, slender stem, pigmented stem, dwarf, elongated pinnae, narrow pinnae and early flowering are screened at M2 generation (total plants screened -1575) following exposure of dry seeds (moisture content -9.3%) of fennel (Foeniculum vulgare Mill., Family: Umbelliferae) to different doses/concentrations of γ-irradiations and EMS.Selfed lines of the mutants are evaluated in M6 generation in comparison to control considering eight phenotypic traits (plant height, number of primary branches/plant, total branches/plant, number of compound umbels/plant, number of umbels/plant, number of umbellets of first inflorescence, seed yield and harvest index).Statistical test (Duncan's test at 5% level of significance) reveal that thick stem mutant is a promising mutant for direct use; while, the rest may be exploited by efficient breeding.
