This study
describes the impact of different concentrations ofmaltose on plant
regeneration of anther culture for five genotypes of rice (Oryzasativa). N6 medium
was used for calli induction, while N6 medium supplemented with
different concentrations of maltose, 2.0 mg/L NAA and 0.5 mg/L kinase was used
for plant regeneration.The result showed that during theinitial
stages of calli induction the anther cultures had varying rates of calli
formation among genotypes, with the best frequency being observed for Dreami2/CaMsrB2-8-DH-1
with a calli frequency of 27.8%.Different genotypes of rice cultured
in regeneration media showedvarying plantlet regeneration on
media supplemented with different concentrations ofmaltose, with low
concentrations (0.04g/L) leading tolow frequency regenerationplantlet but
high green plant production. Indeed, when Dreami2/CaMsrB2-8-DH-2 and
Dreami2/CaMsrB2-8-DH-5 were cultivated under these conditions, 100% green
plants were observed. Anothergenotype also showed a small rate of
albino frequency in response to the lowest concentration of maltose, while
increased maltose concentrations
