Petunia has long been valued for its aesthetic appeal, but recent research has begun to shed light on its possible medicinal properties. <em>Petunia × hybrida</em> is widely recognized for its medicinal characteristics, phytochemical content, and potential health benefits. A research study was undertaken between the years 2021 and 2022. The field experiment was laid out in a randomized complete block design (RCBD), with 11 treatments replicated three times. The treatments included 10 GA3 concentrations from 25 to 250 ppm applied 45 days post-transplantation, along with control—Petunia cv. 'White' seedlings were transplanted in main plots with 30 × 30 cm spacing. Based on the results, it was noted that foliar feeding the leaves with 200 ppm GA3 produced notable outcomes in various characteristics. This treatment recorded a higher plant height (53.45 cm), spread (50.32 cm), and branches per plant (26.77 cm). It also minimized time to first flowering (78.81 days), 50 % flowering (96.67 days), and peak flowering (107.33 days). Furthermore, 200 ppm GA3 optimized flowering duration (123.47 days), flower diameter (6.76 cm), flowers per plant (405.60), seeded capsules per plant (367.13), and seeds per capsule (535.67).

Molecular analysis of variance demonstrated a substantial proportion of variation among individuals (46 %), followed closely variation among individuals (43 %), with the least variation observed within population (11 %). Concurrently, analysis of morphological data, encompassing twenty phenotypic characteristics, revealed significant variation (P ≤ 0.01) among almost all the tested genotypes for recorded parameters, as indicated by combined analysis of variance across sites. These findings underscore the high diversity among the studied genotypes, suggesting a considerable potential for crop improvement through direct selection and intra-specific hybridization strategies. From the perspectives of both conservation and utilization of tef genetic materials, there is a pressing need for more extensive and systematic molecular level research.
