Common bean (Phaseolus vulgaris L.) exhibits a wide range of seed coat colors and this morphological trait is widely used in cultivar identification and assessment of diversity within this species. With an advancement in technology and informatics, new methods of assessing seed color are emerging in addition to traditionally used visual observation. Due to a great variety of color measuring techniques, the evaluation of the agreement between methods is needed prior to using the methods interchangeably. Seed coat color in terms of CIE L*a*b* color coordinates of 100 common bean accessions belonging to five mono- colored landraces was assessed using two methods, colorimeter and Computer vision. The percentage difference between the two methods across all samples for L* color coordinate was 5.81%, for a* color coordinate 23.32% and for b* color coordinate 44.44%. According to Bland- Altman difference plot there is a considerable lack of agreement between the two methods. However, using stepwise discriminant analysis revealed that colorimeter method correctly classified 97% of accessions into their respective landrace, while the classification success of the Computer vision was 99%.

Common bean is one of the most cultivated and consumed grain legumes worldwide, showing a high level of genetic diversity. Here is presented a detailed review of development and mapping of simple sequence repeats (SSRs, microsatellite markers) in the common bean. In the last 25 years, common bean has been the subject of numerous genetic studies, in which the identification and use of SSRs were conducted, and lead to the development of genetic maps. First genetic maps of common bean have been developed in the 1990s and were based on different molecular markers, and included domestication genes and important agronomic traits. Later, SSRs allowed the genetic mapping of more narrow crosses that are often of interest in plant breeding. Most genetic maps have been correlated with the core map established in the recombinant inbred population BAT93 x Jalo EEP558, and includes different markers, RFLP (restriction fragment length polymorphism), RAPD (random amplified polymorphic DNA), AFLP (amplified fragment length polymorphism), and SSRs in particular. More than 2,000 SSR markers are available for the common bean and they are an important tool to evaluate the genetic diversity of common bean landraces. SSRs are also useful to evaluate intra-specific diversity within the genus Phaseolus., Grah je jedna od najviše uzgajanih i najviše korištenih zrnatih mahunarki u svijetu koja ima visoku razinu genetske raznolikosti. U ovom radu je prikazan detaljan pregled razvoja i kartiranja mikrosatelitnih biljega (SSR, ponavljajuće jednostavne sekvence) kod graha. U posljednjih 25 godina, grah je bio predmetom brojnih genetskih istraživanja u kojima je provedena identifikacija i upotreba SSR-ova što je dovelo do razvoja genetskih karata. Prve genetske karte graha su razvijene u 1990-ima i bile su bazirane na različitim molekularnim biljezima, a uključivale su gene koji su povezani uz udomaćenje i važna agronomska svojstva. Kasnije su SSR-ovi omogućili genetsko kartiranje križanaca koji su često od interesa u oplemenjivanju bilja. Većina genetskih karata povezana je s osnovnom genetskom kartom uspostavljenom na rekombinantnoj inbred liniji BAT93 x Jalo EEP558, koja uključuje različite biljege kao što su RFLP (polimorfizam dužine restrikcijskih ulomaka), RAPD (nasumično umnožena polimorfna DNA), AFLP (polimorfizam dužine umnoženih ulomaka) te SSR-ove. Više od 2 000 SSR biljega je dostupno za grah i oni su važan alat za procjenu genetske raznolikosti tradicijskih kultivara graha. SSR-ovi su također korisni za procjenu unutarvrsne raznolikosti unutar roda Phaseolus.
