Coefficient of parentage; Genetic diversity; Germplasm characterization; Joint analysis; Sugarcane varieties

The success of the development of new sugarcane varieties is associated with the ability to correctly select the genitor. The aim of this study was to evaluate the genetic diversity between 113 clones and sugarcane varieties using the Ward-modified location model procedure with added information about the coefficient of parentage and endogamy. In this study, data was used from 100 ... more

Genetic diversity; Germplasm characterization; Multivariate analysis; Saccharum spp

We evaluated the genetic diversity of 77 clones of sugarcane used in crosses made by the Brazilian interuniversity network for the development of the sugar/energy sector (RIDESA) breeding program. Characterization of the genotypes was carried out at the ratoon stage, based on eight morphological traits and seven agronomic traits. Diversity analysis was carried out beginning with the Ward ... more

Genetic diversity; Mangalarga Marchador horse; Population genetic structure

One hundred and fifteen unrelated Mangalarga Marchador horses were sampled from three geographically distinct regions of Minas Gerais State, Brazil (South, Southeast, and Northeast) and tested for 10 microsatellite loci. Genetic diversity and population structure parameters were estimated with ARLEQUIN 3.0, CERVUS 2.0, POPGENE 1.31, GENEPOP on the web, STRUCTURE 2.0, and SPAGEDI 1.2 ... more

Genetic diversity; Germplasm conservation; Maize; Random amplified polymorphic DNA

Ten maize accessions (NC-9, A50-2, M-14, B-42, NC-3, T-7, N-48-1, B-34, USSR, and WFTMS) were studied to estimate the genetic distance on molecular level by random amplified polymorphic DNA. These accessions were selected on the basis of their variable responses against different levels of moisture. Twenty-five primers were used to test genetic diversity, of which 14 were observed to be ... more

Genetic diversity; Polymerase chain reaction; Random amplified polymorphic DNA; Sugarcane

Genetic diversity of 20 sugarcane accessions in Pakistan was studied using 21 random amplified polymorphic DNA markers. The mean genetic distance between the cultivars was 39.03%, demonstrating that a large part of the genome is similar among the accessions. This probably arises from a lack of parental diversity, with few clones, which are themselves related, contributing to the parentage ... more

Blackthorn; Genetic diversity; Prunus spinosa; Random amplified polymorphic DNA

Prunus spinosa, blackthorn, exists as wild populations that inhabit uncultivated uplands of Coruh Valley in the northeastern part of Turkey; the fruit is used to make preserves. We examined genetic diversity in wild-grown Prunus spinosa; 16 individual plants from wild populations of Coruh Valley were sampled and subjected to RAPD (random amplified polymorphic DNA) ... more

Ficus; Genetic diversity; Random amplified polymorphic DNA; Wild fig

The fig tree (Ficus carica L.) is of significant socio-economic importance in Turkey, with 25% of the world’s fig production. Genetic variation and relationships among 14 wild-grown figs sampled from Coruh Valley in Turkey were characterized by random amplified polymorphic DNA (RAPD). Ninety-eight DNA fragments were scored after amplification of DNA samples with 13 random primers ... more

Degree of divergence; Genetic diversity; Plantago; RAPD markers

Plantago ovata, popularly known as isabgol, has great commercial and medicinal importance due to thin rosy white membranous seed husk. Isabgol seeds and husks have emollient, demulcent and laxative properties. We used both biometric and molecular techniques to assess the genetic variability and relatedness of 80 germplasm accessions of Plantago spp (P. ovata, ... more

Genetic diversity; Malus; Random amplified polymorphic DNA; Rootstocks; Turkey; UPOV

Two local (Vezir-1 and Vezir-2) and two standard (M9 and MM106) clonal apple rootstocks were compared using both morphological and molecular markers. International Union for the Protection of New Varieties of Plants criteria were used for morphological evaluation, which did not clearly separate these rootstocks. We tested 47 random decamer primers for random amplified polymorphic DNA analysis ... more

DNA markers; Genetic diversity; Random amplified polymorphic DNA; Sunflower diversity

The genetic diversity among eight sunflower lines was determined through the estimation of the random amplified polymorphic DNA method. One hundred and fifty-six DNA fragments were generated by 20 random primers, for an average of about 7.8 bands per primer. Of these amplified DNA fragments, 104 were polymorphic among the eight sunflower lines. Nei and Li’s similarity matrix gave values from ... more
