Abstract

This work was undertaken during the years 2003, 2004, 2005,2006 and 2007 for improving the productivity of Balady mandarin(Citrus reticulate Blanco). Firstly, selection and evaluation of somemandarin seedlings trees were conducted based on yield (fruit quantityand fruit quality); such trees would be considered as mother trees.Secondly, after selection and evaluation, mass production of theselected superior genetic materials (individual trees) was propagatedby means of tissue culture technique as it is rapid clonal propagationmethod to rescue the lose of such limited selected source. The resultscould be summarized as follows:I-Selection and evaluation of some superior variants of mandarinincluded; number of fruits/tree, yield/tree (kg), fruit weight(g), fruitvolume (cc), peel thickness (cm), number of seeds/fruit, T.S.S.%,acidity % and vit. C (mg/100ml. juice) content. The results showed thatsome promising mandarin trees with high yield and good fruit qualitywhich could help in improving mandarin productivity in FayoumGovernorate, Egypt, were detected.II- Mass production using shoot tip technique. MS basal medium 1962at full strength supplemented by 1.5 mg/L BA was sufficient for thebest shooting proliferation of mandarin. MS basal medium plus 1.5mg/L NAA significant increased the rooting percentage, number ofroots and root length of citrus speciesIII- Anatomical studies show that MS (Murashinge Skoog BasalMedium) supplemented with 1.5 mg/L NAA enhanced adventitiousroots formed from callus and cambium (i.e. high rooting percentage),in comparison to the low concentration 0.5 – 1.0 mg/L whichadventitious roots were formed only from cambial zone (low rootingpercentage).
