Effect of Radiation on Nuclear Embryogenesis in Sweet Orange Cultivars

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
