“…This can facilitate selection of ecotypes with variable tolerance to drought stress. Similar patterns of association among geographical characteristics with days to flowering, plant height, number of shoots per plant, and palatability have been reported by Zarrabian et al (2013) in sainfoin. Kerman is one of the driest provinces in southeast Iran.…”

Ecotypes of sainfoin (Onobrychis viciifolia Scop.) have not been extensively studied, and knowledge about their variation is generally limited. In the present study, 100 sainfoin genotypes from 10 ecotypes were clonally propagated and evaluated under water‐stressed and nonstressed conditions for 2 yr. Among‐ and within‐ecotype variation plus heritability of agronomic, morphological, and physiological traits were estimated and the associations of traits were determined. For most of the measured traits among‐ and within‐ecotype effects were significant. The variance within ecotypes was at least four times higher for most of the measured traits when compared with variance among ecotypes. The within‐ecotype contribution was 67 to 71% for dry matter yield (DMY), 69% for number of stems per plant, and 69 to 91% for morphological traits. Large within‐ecotype variation for DMY and yield‐related traits could express yield stability across environments and maximize genetic progress per breeding cycle. The lowest heritability estimates were obtained for DMY and leaf‐to‐stem ratio, and the highest one was estimated for antioxidant activity and chlorophyll content. Water stress caused significant decrease in all measured traits except for carotenoid content, proline content, catalase, ascorbate peroxidase, and superoxide dismutase activity. Genotypic differences for water‐stress tolerance identified in this study were mainly attributed to the ability of tolerant ecotypes to accumulate a greater amount of proline in their leaves in response to water stress. Dry matter yield had positive correlations with plant height, inflorescence length, number of stems per plant, and proline content under both moisture environments. On the basis of factor analysis, the first three factors in both environments were considered as “forage yield components,” “photosynthetic pigments,” and “antioxidant activity.” High within‐ecotype variation indicated the importance of selection within populations for suitable parental materials in sainfoin breeding. Baft was the best ecotype under both moisture environments in this respect.

“…However, this distinction may be the reflection of different domestication routes with different ancestors. Using morphological, anatomical, and ISSR traits on 80 accessions of O. viciifolia, Zarrabian et al (2013) showed that the high level of population differentiation may comply with the theoretical prediction from an "isolation by distance" model. In this model, total population is assumed to be divided into subgroups, each breeding at random within itself.…”

“…This genus contains various annual and perennial species that can be distinguished mostly by their morphology and geographical distribution extending from the western Himalayas to Caucasia, Eurasia, North America, and Africa (Pavlova and Monova, 2000). However, almost all the Onobrychis species are restricted to northwestern Asia, especially to Iran and Anatolia, making this area the specific home of this genus diversity (Yildiz et al, 1999;Zarrabian et al, 2013).…”

Little is known about the taxonomic relationships of the genus Onobrychis (Fabaceae). To study inter-and intraspecific variations and the relationships among the species, 102 accessions (33 species) of the genus Onobrychis were evaluated using 22 intersimple sequence repeat (ISSR) markers. Almost all the species belonging to the section Onobrychis clustered together. A similar pattern was found with the species belonging to the section Hymenobrychis, while those of the section Lophobrychis did not cluster together. The results indicate that the section Lophobrychis has a comparatively derived organization that can be attributed to the differences in their taxonomic delimitation. Geographical pattern was found to be associated with the genetic diversity within the species. Principal coordinates analysis (PCoA) indicated a high association among the sections Lophobrychis, Heliobrychis, and Hymenobrychis. Thus, the present subgeneric classification of Onobrychis (Onobrychis and Sisyrosema) was not supported. The results based on Nei's similarity suggest that some species in the genus Onobrychis (especially O. altissima) might have been outcrossing with reproductive ability with O. viciifolia. Our results suggest that species with x = 7 chromosome are closer to O. viciifolia than to those with x = 8. Therefore, a base number n = 8 can be assumed for this genus (within Onobrychis genus basal), changing to 7 through aneuploid loss.

“…Several researchers used ISSR markers to study genetic diversity within and among populations of forage crops (Bolourchian et al, 2013;Jonaviclene et al, 2009;Zarrabian et al, 2013;Shirvani et al, 2013). Better reproducibility of products of ISSR bands compared to other markers such as RAPD could be due to its longer SSR-based primers with higher annealing temperatures (Huangfu et al, 2009).…”

Genetic diversity of Trifolium quartinianum accessions from Ethiopia were studied using Inter Simple Sequence Repeat (ISSR) markers. A total of 24 accessions, divided into three populations were used for the present study. DNA was extracted from a bulk of samples using a modified CTAB method. A total of 84 bands were amplified by the four di-nucleotid ISSR primers in the overall experimental materials. Genetic diversity was high at the species level (PPL = 100%, h = 0.29, I = 0.44). Comparison of population-based genetic diversity showed that Gojam population was the most diverse. Analysis of molecular variance (AMOVA) revealed high level of within-population variation with 83.13%. Unweighted pair group method with arithmetic average (UPGMA) and Principal Coordinate (PCO) analysis showed that only accessions of T. quartinianum from Gondar formed separate cluster. The study clearly indicates the presence of variable genotypes with their unique identity that deserve conservation attention.
