IN VITRO NUCELLAR EMBRYOGENESIS IN MONO- AND POLY-EMBRYONIC MANGO CULTIVARS

Mango (Mangifera indica L.) seems to be difficult plant material with respect to tissue culture response. Nucellar embryogenesis can be gainfully utilized for production of uniform rootstock. We report here genotypic response of certain mono- and poly-embryonic mango cultivars under in vitro condition. Among all the cultivars, polyembryonic cultivars gave higher level of somatic embryogenesis in comparison to monoembryonic. Among all polyembryonic cultivars ‘Bappakai’ produced 187.33 embryos per explant followed by ‘Kurukkan’ 158.33 embryos per explant and ‘Movandan’ 146.45 embryos per explant, whereas mono-embryonic cultivars show a comparatively lower level of somatic embryogenesis.
