Abstract:
All the Thirteen sweet orange cultivars which were tested for nuclellus embryos in MS + BA (0.5 mg/I) + Glutamine 5 rrigil responded to embryogenesis. After two months culture period, the maximum (7.0) coefficient of nuclellar regeneration (CNR) was of cultivar Mosambi, which has minimum ovvule weight (0.11 cm) and the minimum CNR was of Moro blood (2.0). The fruit characteristics like fruit weight, diameter, ovule weight, length and diameter have no relations with CNR. The maximum values of CNR were in Valencia (5.07), Succari (5.0), Mosambi (4.58) and in both Mosambi, Succari (3.5), for 3,6,9 and 12 Kr and minimum CNR values were 2.49, 1.66, 1.6, 1.12 in 3,6,9 and 12 Kr respectively.
