“…Onobrychis viciifolia, a summary of the classification (Širjaev, 1925) Genus =OnobrychisHymenobrychis taxonomy of different species within the Onobrychis genus and to determine its evolution. Through the karyotype analysis of different Onobrychis species, it has been suggested that the two populations of Onobrychis transcaucasica should be placed in one group, while Onobrychis altissima and O. viciifolia should be placed in a second group (Massoud et al, 2010). During one of the last karyotype analyses developed in sainfoin, the 2C value was determined to be approximately 2.5 pg (Hayot Carbonero et al, 2013).…”

Onobrychis viciifolia(sainfoin) is a forage legume crop with many positive agronomic, environmental, nutritional and nutraceutical attributes. Farmers also benefit from its drought tolerance in areas of low rainfall and light free draining soil, mainly due to its deep taproot. It is resistant to most common pest and diseases and is a valuable resource for pollinators, specifically cultivated for honey production in some regions. It has many benefits for animals, being highly palatable and without danger of bloat, which can be life-threatening to livestock. Its decline in Northern Europe started during the Green Revolution and was impacted by changes towards more intensive farming. Unlike other forage legume crops such as red clover and lucerne, sainfoin does not respond well to inputs and is difficult to establish and maintain. Sainfoin could be classified as an ‘orphan crop’ with very little genetic improvement or agronomic studies in the past 60 years. In the past 5–10 years, however, there has been a resurgence in interest and this has given rise to a number of studies and initiation of systematic improvement of the crop, which is indispensable to its reintroduction into the farmed environment. Interest has been driven in part by considerable evidence to suggest that condensed tannins present in the legume foliage, together with other polyphenol compounds, have positive effects on animal nutrition together with anthelmintic properties. These compounds are also thought to play a role in environmental benefits. There remain many challenges to address in order to optimize the potential for cultivation of sainfoin and its use as a beneficial forage crop. This review makes particular reference to a recently completed project; ‘Legume Plus’, funded by the European Union and embracing a multi-disciplinary approach to both understand and improve the crop for farmers. The present review covers results from both this project and other studies during the past 5 years, also drawing on historic studies of etymology, taxonomy, genetics, agronomy and botany, aiming to be a useful resource for research and for practical plant breeders and agronomists.

Meiotic chromosome number and behaviour of Onobrychis alborzensis (Fabaceae): a new species from northern Iran

2011

The present study is focused on the cytogenetic and morphological criteria for distinguishing a new taxon belonging to Onobrychis sect. Hymenobrychis. The new species, O. alborzensis RANJBAR & HAJMORADI is described from Alborz Province and illustrated. It is closely related to O. talagonica RECH. F. and O. michauxii DC., but differs from them in a few morphological characters such as plant indumentum, stipule size and shape and size of the leaflets, standard and calyx. Meiotic chromosome number and behaviour were studied in O. alborzensis and O. talagonica. This report is the first cytogenetic analysis of these taxa. O. alborzensis is a diploid plant and possesses the chromosome number 2n = 2x = 14, inconsistent with the base number of O. talagonica witch shows 2n = 2x = 16. The general meiotic behaviour in both species was regular, with bivalent pairing and normal chromosome segregation at meiosis. However, some meiotic abnormalities were observed including varied degrees of sticky chromosomes with laggards, precocious division of centromeres in metaphase I, bridges in anaphase I, laggard chromosomes, micronucleus, asynchronous nucleus, cytomixis and tripolar cells in telophase II.

In this study 40 specimens from 8 representative Iranian populations of Onobrychis viciifolia SCOP. were collected from their natural habitats. The specimens were biometrically assessed using 43 quantitative and 15 qualitative morphological characters. At each sample site we recorded ecogeographical variables. In order to evaluate the difference between the variation due to phenotypic responses and genetic adaptation, we generated nucleotide sequence data from the internal transcribed spacer of the nuclear rDNA genes (ITS) and carried out genomic fingerprints using inter‐simple sequence repeat PCR (ISSR). Cluster analysis of morphological characters divided the eight populations into three major groups. Leaf length, leaflet length and width, calyx length, plant height, and stem length were introduced as diagnostic characters for three different morphological groups. Furthermore, canonical correspondence analysis (CCA) of ecogeographical data showed correlations between morphological variations and ecogeographical factors. Clay%, saturation percentage (SP), total neutralizing value (TNV%), texture, minimum temperature, and geographic separation were the main environmental variables associated with morphological groups of O. viciifolia. ISSR analysis revealed three main groups which are in correspondence with morphological groups, indicating that the three morphological groups have been shaped by genetic and phenotypic responses to environmental conditions.
