Background. The peanut is one of the most important oil crops suitable for cultivation in the tropical areas of the world. Despite its agronomic importance, few studies have been carried out to assess the morphogenetic diversity of Arachis hypogaea L., especially in East African countries. The major interest of this morphologic study lies in the potential of this species to provide useful genes for the improvement of cultivated peanuts. To date, no study has been performed in Algeria to characterize local peanut varieties.Materials and methods. Thirty peanut accessions were collected from four principal areas of peanut production in Algeria. Genetic characterization using 15 agronomic characters and 25 morphological descriptors showed a high level of diversity among accessions. Principal Component Analysis and the Hierarchical Ascendant Classification were made to clarify the genetic relationship between peanut accessions.Results and discussion. Results showed that leaflet size (length and width), seed shape and size, oil content, and branching pattern were the principal characters to discriminate the screened A. hypogaea accessions. In addition to that, the weights of 10 pods and 100 seeds were the most variable traits and presented a CV of 42.53% and 40.12%, respectively. On the other hand, total storage proteins extracted were separated using SDS-PAGE and revealed thirty bands that were used to generate a matrix and make a cluster analysis using the UPGMA method, exhibiting different storage proteins compositions. Moreover , the phenotypic diversity observed agrees with the storage protein profile diversity, while the accessions grouped in similar clusters belong to the two subspecies of A. hypogaea. The results of the current study show that morphological traits and seed storage proteins can be useful for exploring the diversity among A. hypogaea accessions.

“…That is why morphological traits have been widely used in the assessment of variability within different plant species including rice (Caldo et al 1996), Carthamus tinctorius L. (Shinwari et al 2014), Iris (Azimi et al 2016), wheat (Bellatreche et al 2017), Psidium guajava L. (Kidaha et al 2015), Capsicum sp. (Agyare et al 2016), Solanum macrocarpon L. (Saka et al 2017), Arachis hypogaea L. (Neya et al 2018), common bean (Boros et al 2014), Hoary cress (Roughani et al 2018), and Bidens pilosa L. (Ngezahayo et al 2018). Although genetic variation in tomato by morphological features has been the subject of many studies around the world (Agong et al 2001, Mazzucato et al 2008, Al-Aysh et al 2012, Osei et al 2014, Chime et al 2017Yadav et al 2017;Kouam et al 2018), no work on cultivated tomato in Burundi has been conducted to our knowledge.…”

Ngezahayo F, Ngendakuriyo Jc, Bizindavyi E, Mbonihankuye C. 2019. Short Communication: Agro-morphological diversity among four tomato cultivars in western Burundi. Biodiversitas 20: 436-441. Since crop cultivars represent a reservoir of genetic diversity; essential are the understanding and the utilization of genetic variation in tomato accessions for improving the crop. The objective of the present study was to characterize 4 tomato cultivars from the western Burundi by means of 8 agro-morphological traits that could be exploited for tomato crop improvement. Tanya and P20 cultivars showed the lowest plant height but the highest flower number, fruit number and yield per cultivar. This was corroborated by a significant negative correlation between plant height and flower number, fruit number and yield per cultivar in overall results. On the other hand, Floradel and Tengerou97 cultivars have the highest stem circumference and leaf number. Cluster analysis also showed almost four clusters corresponding to one cluster for each cultivar, though Tengerou97 and Floradel tend to be grouped together. Finally, principal component analysis showed that all the eight agro-morphological traits participated in grouping tomato cultivars; particularly flower number, fruit number, plant height, and yield per cultivar. The first three principal component axes accounted for 92.465% of total variation observed among tomato cultivars. Thus, the four cultivars should all be exploited in tomato breeding and improvement programs.

“…Traditionally, morphological traits were used to evaluate genetic divergence and classify existing germplasm materials [10]. Neya et al [11] indicated that morphological characterization allows identification of varieties or accessions from a collection and contributes to increased understanding of genetic diversity. Also, assessment of genetic diversity using morphological traits allows for determining variability in the presence of differences in environmental conditions which cannot be disregarded from the genotypic variation [9].…”

Genetic diversity in crops is critical for advanced crop improvement as it provides alternatives for breeders to develop improved cultivars. Traditionally, morphological traits are used to evaluate genetic divergence and classify existing germplasm. Morphological characterization relies on plants possessing different phenotypic traits to identify the individual. Information on the diversity of peanut grown in Ghana is limited. This study was conducted to determine variation in peanut cultivars in Ghana through morphological characterization. Ninety-five accessions of peanut were collected from three sources across five administrative regions of the country that included farmers, open markets, and research institutes. Morphological characterization comprised 31 characters including 11 quantitative and 20 qualitative traits. Seventy-five percent of the accessions belonged to the fastigiata subspecies. The study revealed through cluster analysis that the accessions were only 30% diverse. Principal Component Analysis of the traits showed that yield attributing traits were the main factor that influences dispersion and superior accessions. These traits included seed length, growth habit, pod length, pod width, plant width, and main stem height. This study demonstrates that phenotypic diversity of peanut cultivars in Ghana is limited.
