Seven F4 recombinant lines of tomato (Solanum lycopersicum L.) were derived from the cross Peto-86 × Supermarmande following a rigid tandem multi-trait selection scheme. Selection was exercised for desirable traits such as fruit firmness, pericarp thickness, redness, total soluble solids (TSS) and fruit yield while discarding the fruit fasciation and deep ribs. These lines were assessed for field performance of horticultural traits with emphasis on fruit firmness. Diversity analysis and to study relationship among the parents and the derived lines based on phenotypic horticultural traits was carried out using RAPD, ISSR and SRAP molecular markers. Tansgressive segregation for fruit firmness was observed in all the lines exceeding the better parent in strength. Three lines (1/A, 2/ A and 2/B) were notable for higher fruit yield. Recombinant line 2/B showed 44.7% increase in yield over the higher yielding parent, Supermarmande. This line also showed high TSS. The recombinant line 1/A was the best among the selected lines for fruit pericarp thickness having greater fruit firmness. Molecular markers data revealed a significant positive correlation with morphological traits indicator suggesting that these independent sets of data are likely to reflect the same pattern of genetic diversity.

The present experiment was carried out to define the efficiency of foliar applications (3 times) with chelated magnesium (0, 200, 400 and 600 ppm) and iron (0, 150, 300 and 450 ppm) for improving growth, productivity and anthocyanins content in calyces of roselle. Results showed that calyces production and their contents of anthocyanins were significantly increased with increasing either Mg or Fe concentration. The combination of Mg at 600 ppm and Fe at 450 was the most effective combined treatment in stimulating number of leaves and flowers, flower weight per plant, calyces dry weight per plant, seed dry weight per plant, weight of 1000 seeds and calyces content of anthocyanins. However, calyx fresh weight attained the highest values when the medium concentration of Mg (400 ppm) combined with Fe at the highest concentration (450 ppm) was employed.

The current experiment was conducted to study the response of Ficus elastica var. decora air-layers to seven treatments of IBA (control, 50 and 100 ppm in rooting substrate, 1500 and 3000 ppm by painting girdled zone, and 1500 and 3000 ppm in talc paste) in the presence of root promoting microorganisms including Bacillus subtilis and arbuscular mycorrhizal fungi (AMF). The obtained results indicated that 3000 ppm IBA applied by painting girdled zone gave a significant increase in rooting percentage and the best root and growth characteristics (number of days for root appearance, number, length, fresh and dry weights of roots per rooted air-layer, survival percentage, plant height and number of leaves and shoots) as well as total content of carbohydrates and phenolics, and showed the shortest period required for root appearance in comparison with the other treatments. Air-layers treated with B. subtilis were superior to those treated with AMF. The best results concerning rooting percentage, root characteristics, total contents of carbohydrates and phenolics, survival percentage, increment in growth of air-layers after six months from detachment were observed in airlayers treated with 3000 ppm IBA by painting girdled zone in combination with B. subtilis followed by the same IBA treatment combined with AMF.
