Abstract
The main objective of the present programme was to widen the varietal range of early ripening peach cultivars. Crosses were made between Shan-i-Punjab x Florda Prince, Shan-i-Punjab x Flordaglo and Shan-i- Punjab x Prabhat. The embryos of these crosses were rescued after 65, 75 and 85 days of crossing and cultured in MS basal medium supplemented with varying concentration of BAP (0 to 2 mg/l) and IBA (0 to 1 mg/l). After stratification at 4°C, the embryo cultured tubes were transferred to a growth chamber at 24 ± 2°C for germination. Seeds harvested at 85 days after crossing showed maximum embryo germination (75.26%). Among these crosses, hybrid-3 (Shan-i-Punjab x Prabhat) showed maximum germination (81.66%) in M2 medium (MS medium + BAP 0.25 mg/l + IBA 0.05 mg/l) when rescued after 85 days of pollination. Embryos harvested at fully matured stage (85 days after pollination) took minimum days to germinate.
