“…Although such comprehensive surveys of genetic variation have not since been carried out, induced and spontaneous mutants affecting a variety of traits have been described in this period. For instance, a gene controlling symbiosis, sym-1 , was described by Duc and Picard ( 1986 ). Duc et al ( 1999 ) reported a recessive allele of the i1 locus conferring a green cotyledon; this has a similar phenotype as the green cotyledon allele of the Sc locus, mapped by Khazaei et al ( 2014 ) to chromosome IV.…”

Vicia faba L, is a globally important grain legume whose main centers of diversity are the Fertile Crescent and Mediterranean basin. Because of its small number (six) of exceptionally large and easily observed chromosomes it became a model species for plant cytogenetics the 70s and 80s. It is somewhat ironic therefore, that the emergence of more genomically tractable model plant species such as Arabidopsis and Medicago coincided with a marked decline in genome research on the formerly favored plant cytogenetic model. Thus, as ever higher density molecular marker coverage and dense genetic and even complete genome sequence maps of key crop and model species emerged through the 1990s and early 2000s, genetic and genome knowledge of Vicia faba lagged far behind other grain legumes such as soybean, common bean and pea. However, cheap sequencing technologies have stimulated the production of deep transcriptome coverage from several tissue types and numerous distinct cultivars in recent years. This has permitted the reconstruction of the faba bean meta-transcriptome and has fueled development of extensive sets of Simple Sequence Repeat and Single Nucleotide Polymorphism (SNP) markers. Genetics of faba bean stretches back to the 1930s, but it was not until 1993 that DNA markers were used to construct genetic maps. A series of Random Amplified Polymorphic DNA-based genetic studies mainly targeted at quantitative loci underlying resistance to a series of biotic and abiotic stresses were conducted during the 1990's and early 2000s. More recently, SNP-based genetic maps have permitted chromosome intervals of interest to be aligned to collinear segments of sequenced legume genomes such as the model legume Medicago truncatula, which in turn opens up the possibility for hypotheses on gene content, order and function to be translated from model to crop. Some examples of where knowledge of gene content and function have already been productively exploited are discussed. The bottleneck in associating genes and their functions has therefore moved from locating gene candidates to validating their function and the last part of this review covers mutagenesis and genetic transformation, two complementary routes to validating gene function and unlocking novel trait variation for the improvement of this important grain legume.

“…Subsequently, genetic markers could be assigned to physical chromosomes ( vaz Patto et al , 1999 ). In addition, genes controlling rhizobial symbiosis and pigment composition were identified ( Duc and Picard, 1986 ; Duc et al , 1999 ), with segregating recombinant inbred lines (RILs) being used to determine the Mendelian inheritance of a seed dormancy gene ( Ramsay, 1997 ). Parental germplasm resources from early faba bean research are still available ( O’Sullivan and Angra, 2016 ).…”
