Abstract
This research utilized a multi-faceted approach, combining surveys, morphological analysis, and genetic assessment to evaluate the diversity of Talinum triangulare in Mid-Western Nigeria. Initially, a structured questionnaire was administered to 50 participants to gather socio-economic data related to the plant's usage in the study area. Subsequently, 20 accessions were randomly collected from ten sampling stations in Edo and Delta States, Nigeria, using Arc GIS Pro for mapping purposes. Morphological traits, including plant height, leaf length, leaf area, number of leaves, stem girth, and plant dry weight, were measured in triplicate. Genetic diversity was assessed using Simple Sequence Repeats (SSR) genotyping. Data analysis involved descriptive statistics, ANOVA, and LSD at a 5% significance level, providing insights into the morphological and genetic variation of T. triangulare. The survey revealed the socio-economic significance of T. triangulare, with a high percentage of female respondents (90%) and traders (36%). Morphological analysis showed significant variations in plant height, leaf length, and leaf area. Genetic diversity assessment using SSR markers revealed moderate genetic diversity (GD = 0.43) and significant molecular variance. Phylogenetic analysis identified distinct genetic profiles and clusters, indicating shared ancestry and genetic divergence. These findings emphasize the importance of conserving the genetic diversity of T. triangulare for sustainable agriculture and highlight its potential for breeding programs. The research demonstrates the value of integrating socio-economic, morphological, and genetic analysis to understand and preserve plant diversity.
