Genetic diversity and relationship of Tunisian castor (Ricinus communis L.) genotypes revealed by SSR markers

RAPD markers are used to study the genetic diversity of the main planting on 37 castor varieties widely cultivated in china according to the oil content and other characteristic of different castor varieties. Genetic distance of 37 Chinese castor varieties is studied by RAPD markers analysis. RAPD analysis shows that a total of 122 bands are amplified from random primers of 20 S series, including 71 polymorphic bands with polymorphic rate of 58.20%. 37 castor beans are divided into four major groups in the phylogenetic tree. One castor germplasm is included in1, 2, 3 groups respectively, and two sub-groups are included in the 4 major group.

Ricinus Communis L

Castor oil plant (Ricinus communis L.) is an important oil crop with little research attention in Nigeria. In the present research, extent of genetic diversity among 20 Nigerian castor genotypes was determined using morphological descriptors and molecular markers. The genotypes were laid out on a randomized complete block design with three replicated plots. Molecular genotyping of the genotypes was carried out using genomic Simple Sequence Repeats (SSR). The genotypes revealed high divergence in seed colour, seed shape, seed mottle, seed caruncle and seed sizes. Seedling establishment varied from 70.18% (in Acc. 006) to 93.25% (Acc. 001) with average mean of 81.53%. Raceme length ranged from 15.90 cm to 29.54 cm with population mean of 20.80 cm. The highest seed yield (1222.98 kg/ha) was recorded in Acc. 001 and the least (611.46 kg/ha) was observed in Acc. 006. Seed oil content varied between 32.15% in Acc. 042 and 54.03% in Acc. 006. Agglomerative cluster dendrogram constructed from morphological data showed random distribution of the genotypes into three cluster groups irrespective of the sources/collection points. The genetic diversity based on SSR Marker Analysis revealed high average expected heterozygosity (0.74), Polymorphic information content (0.68), Nei’s gene diversity index (0.72) and Shannon's Information index (1.43). The dendrogram constructed from molecular data grouped the twenty genotypes into three groups at coefficient of 0.34. From these findings, it showed that the twenty genotypes evaluated are divergent in nature and they could serve as good genetic material for castor breeding in Nigeria.

Abstract. Sadiyah H, Ashari S, Waluyo B, Soegianto A. 2021. Genetic diversity and relationship of husk tomato (Physalis spp.) from East Java Province revealed by SSR markers. Biodiversitas 22: 184-192. This study aimed to investigate the genetic diversity and relationship of Physalis spp. from East Java province, Indonesia. A total of the 33 Physalis accessions was analyzed employing 16 SSR markers. AMOVA, UPGMA clustering, and non-parametric ANOVA analyses were applied. The results showed Genetic diversity in this sample showed lower levels (He =0.171), as compared to other studies of Physalis that used different molecular markers. The dendrogram revealed the presence of five groups, the different species belong to different small groups. The two major groups consist of accessions originated from eastern Java and Madura Island, indicating that there is no significant difference between accessions from both areas although there is geographic isolation in the form of the strait. It is consistent with the low population differentiation and high genetic drift. The AMOVA revealed that 96% of the total variation came from the within-population (among accession), reflect that the accessions used in this study have high variation and valuable for plant improvement through breeding programs. It is recommended that future evaluation studies include more accession from minor accessions detected in the sample of this study to better represent the genetic diversity available in this crop.
