“…The Fst (a measure of genetic differentiation) obtained in this work was comparable with the findings of Ambreen et al [12] as they obtained Fst in the range 0.08 to 0.29. On the other hand, Mokhtari et al [55] obtained mean Fis value of 0.01 which is lower than that (1.00) presented in this work. Safflower is a self-pollinated crop, higher Fis values are therefore expected.…”

Safflower ( Carthamus tinctorius L.) is a multipurpose crop of dry land yielding very high quality of edible oil. Present study was aimed to investigate the genetic diversity and population structure of 131 safflower accessions originating from 28 different countries using 13 iPBS-retrotransposon markers. A total of 295 iPBS bands were observed among which 275 (93.22%) were found polymorphic. Mean Polymorphism information content (0.48) and diversity parameters including mean effective number of alleles (1.33), mean Shannon’s information index (0.33), overall gene diversity (0.19), Fstatistic (0.21), and inbreeding coefficient (1.00) reflected the presence of sufficient amount of genetic diversity in the studied plant materials. Analysis of molecular variance (AMOVA) showed that more than 40% of genetic variation was derived from populations. Model-based structure, principal coordinate analysis (PCoA) and unweighted pair-group method with arithmetic means (UPGMA) algorithms clustered the 131 safflower accessions into four main populations A, B, C, D and an unclassified population, with no meaningful geographical origin. Most diverse accessions originated from Asian countries including Afghanistan, Pakistan, China, Turkey, and India. Four accessions, Turkey3, Afghanistan4, Afghanistan2, and Pakistan24 were found most genetically distant and might be recommended as a candidate parents for breeding purposes. The findings of this study are most probably supported by the seven similarity centers hypothesis of safflower. This is a first study to explore the genetic diversity and population structure in safflower accessions using the iPBS-retrotransposon markers. The information provided in this work will therefore be helpful for scientists interested in safflower breeding.

“…These findings explained the results obtained in this study. The number of alleles found in this study was lower than that reported by Kiran et al (2017) and higher than that reported by Mokhtari et al (2018), probably because the number of genotypes evaluated in those studies was different.…”

“…However, the average number of alleles per locus in their study was four, which was lower than that of our study. Mokhtari et al (2018) studied the genetic divergence of 103 safflower genotypes using 32 SSR molecular markers and found a lesser number of alleles than that in our study, ranging from two to four and an average of three alleles per locus.…”

Genetic variability in genotypes of safflower via SSR molecular marker

et al. 2023

The safflower is an oleaginous plant belonging to the Asteraceae family. It is used as a raw material for various purposes. These plants are popular for the quality and quantity of oil produced and, and thus, studying their genetic variability using markers is necessary for determining genetic resources to conduct breeding programs. Therefore, we evaluated the genetic variability of safflower genotypes using Simple Sequence Repeat (SSR) molecular markers. The study was conducted at the State University of Mato Grosso “Carlos Alberto Reyes Maldonado”, in the Campus of Cáceres-MT. In total, 121 safflower genotypes from the Germplasm collection were evaluated using 21 SSR markers. The programs GenAlEx 6.5, GENES, and Structure were used to analyze the data. We identified 158 alleles at 21 loci among the genotypes. The expected heterozygosity (He) was high (0.551 - 0.804), but the observed heterozygosity (Ho) was low (0.000 - 0.502), and the indices of the endogamy coefficient (F) were positive in all loci and all populations, with an overall average of 0.958. The genetic differentiation (FST) values among populations were low, with an average of 0.010, which suggested a low population structure. The modified Tocher clustering and the UPGMA hierarchical clustering yielded 19 and 15 distinct groups, respectively. The genetic structure showed two populations, with few intermixes in the genome. The evaluated safflower genotypes showed genetic variability, and these genetically different variants might be used in breeding programs to obtain cultivars adapted to Brazil.

O Carthamus tinctorius L. é uma das espécies mais antigas do mundo, é uma oleaginosa pertencente à família Asteraceae, cuja matéria-prima é destinada para diversos fins. A cultura tem atraído a atenção de pesquisadores e indústrias por possuir alta qualidade e quantidade de óleo, neste contexto o que torna importante a realização de estudos, principalmente no melhoramento genético, que auxilia na seleção de genótipos superiores. Diante disso, o presente trabalho objetivou-se desenvolver uma revisão de literatura sobre a cultura do cártamo, mostrando algumas informações sobre seu cultivo, principais usos e sobre a variabilidade genética da mesma. Através do estudo feito em artigos científicos, livros e periódicos pode-se familiarizar os leitores sobre a cultura do cártamo, pois ainda no Brasil é pouco estudada e informações principalmente sobre seu cultivo e produção ainda são escassas, mas alguns trabalhos apresentados mostra o potencial que o Brasil tem para o cultivo do cártamo, sendo necessários estudos de melhoramento genético para extrair o máximo potencial da espécie.
