The experiment was carried out to investigate the performance of dessert banana cultivars at Raya Azebo with the aim of selecting well adaptable and high yield banana cultivar/s. To achieve the goal of the study, the experiment was laid out in randomized complete block design and replicated thrice. From the experiment, different growth, phenological, yield, and yield-related data were collected, and analyzed using SAS software version 9.3. Dwarf Cavendish cultivar flowered earlier (549.70 days). The maximum number of days (627.20) from planting to fruit setting was recorded on Ducase Hybrid cultivar. Ducase Hybrid gave significantly the maximum bunch weight for the mother (21.04 kg) and daughter (24.53 kg) tree. The maximum number of hand bunch‑1 was recorded on Ducase Hybrid cultivar on both mother (11.31) and daughter (12.17) tree. Ducase hybrid gave significantly the maximum (357.80 qt/ha) marketable fruit yield hectare‑1on the mother tree. On the daughter tree, Ducase hybrid gave significantly the highest (392.5 qt/ha) marketable fruit yield hectare­-1. The average of mother and daughter tree cropping cycle revealed that Ducase hybrid gave first ranked highest marketable fruit yield (375.15 qt/ha), but sensitive to wind. Williams‑I gave the second ranked highest (334.95 qt/ha) marketable fruit yield hectare‑1. Thus, Williams-I cultivar is recommended for the local area. Further, study on water requirements and biochemical content is crucial.

Polyploid seeds production is laborious, complicated, and costly work. Tetraploid and triploid plants produce a fewer number of seeds/fruit, and triploid embryos are fairly weak, covered with a more hardened seed coat as compared to diploid seeds. Here we investigated the interactive effect of new grafting technique of polyploid watermelon scion onto rootstock on plants' survival rate, biochemical, and hormones contents. In this study, three different branches, apical meristem (AM), branch with 1 node (1N), and 2 nodes (2N) from di, Tri, and tetraploid watermelon plants, were used as scion and grafted onto squash rootstock. The results showed highly significant differences between polypoid watermelon when 1N using as a scion, tetraploid showed maximum survival rates, higher contents of hormones, and antioxidants (AOX) activities, compared to diploid, these may be the possible reasons for high compatibility in tetraploid and degrading the grafting zone in diploid. RTq-PCR results confirm that the expression of genes linked to compatibility is consistent with the hormonal and AOX activities. This study provides an alternative and economical approach to produce more tetraploid and triploid plants for breeding or seeds production by using branches as scions.
