“…In pigeonpea plants with determinate growth habit, inflorescence is short, the apical bud develops into a flower, the sequence of inflorescence production is basipetal (Sheldrake 1984) and flowers occur more or less in the same plane (Gupta and Kapoor 1991). Determinate faba bean plants are characterised by a terminal inflorescence (ti) after four to five flowering nodes that results in a considerable reduction of plant height and lodging (Torres et al 2010). In determinate soybean plants, stems terminate in an inflorescence (Woodworth 1932).…”

Chickpea (Cicer arietinum L.) is an indeterminate plant and produce excessive vegetative growth that acts as a competitive sink for developing pods resulting in reduced fruit set whenever soil moisture and temperature conditions are favorable. Determinate genotype was so far not available in the world chickpea germplasm. Determinate chickpea is needed to change its plant architecture in order to achieve a breakthrough in its productivity and stabilize yields in cool and long-season sub-tropical environments of semi-arid tropics. A true breeding determinate chickpea genotype was developed for the first time in the breeding programme. The objectives were to study: (i) the new found determinate genotype BGD 9971 for important plant characteristics and (ii) the genetics of determinate growth habit in it. Determinate genotype was bushy, compact and dwarf in its morphology; the stem growth terminated by a flower and produced 1-4 seeds per pod. The segregation patterns in the F 2 and F 3 of the two crosses (BGD 72 9 BGD 9971 and BGD 128 9 BGD 9971) involving indeterminate and determinate parents have shown that the determinate growth habit in BGD 9971 was governed by two recessive genes. The genes for determinacy in BGD 9971 were designated as dt1 and dt2. The homozygous recessive for both alleles (dt1dt1dt2dt2) produced a determinate phenotype. The utilization of genes identified for determinacy in the newly developed BGD 9971 has the major impact on chickpea breeding for better adaptation to cool climate, high fertility and irrigated environments.

“…Marker-assisted selection (MAS) in faba bean is less advanced than in some other legume species, but significant efforts have been made to enrich genetic and genomic resources in this crop (Torres et al 2010Alghamdi et al 2012), fortified by comparative genomics with M. truncatula and other legumes (Ellwood et al 2008;Kaur et al 2012;Torres et al 2012;Khazaei et al 2014). Genomic and transcriptomic approaches, now being applied in faba bean, open new opportunities for fine mapping or uncovering of candidate genes.…”

“…Molecular approaches in faba bean breeding have been mostly limited to biotic stresses and anti-nutritional compounds (reviewed in Torres et al 2010Torres et al , 2012, but amongst abiotic stresses, some progress has also been made in identifying QTLs in frost tolerance (Arbaoui et al 2008). Yield, its components, and flowering time (associated with drought avoidance) were fine mapped in faba bean (CruzIzquierdo et al 2012).…”

Use of synteny to identify candidate genes underlying QTL controlling stomatal traits in faba bean (Vicia faba L.)

et al. 2014

We have identified QTLs for stomatal characteristics on chromosome II of faba bean by applying SNPs derived from M. truncatula , and have identified candidate genes within these QTLs using synteny between the two species. Faba bean (Vicia faba L.) is a valuable food and feed crop worldwide, but drought often limits its production, and its genome is large and poorly mapped. No information is available on the effects of genomic regions and genes on drought adaptation characters such as stomatal characteristics in this species, but the synteny between the sequenced model legume, Medicago truncatula, and faba bean can be used to identify candidate genes. A mapping population of 211 F5 recombinant inbred lines (Mélodie/2 × ILB 938/2) were phenotyped to identify quantitative trait loci (QTL) affecting stomatal morphology and function, along with seed weight, under well-watered conditions in a climate-controlled glasshouse in 2013 and 2014. Canopy temperature (CT) was evaluated in 2013 under water-deficit (CTd). In total, 188 polymorphic single nucleotide polymorphisms (SNPs), developed from M. truncatula genome data, were assigned to nine linkage groups that covered ~928 cM of the faba bean genome with an average inter-marker distance of 5.8 cM. 15 putative QTLs were detected, of which eight (affecting stomatal density, length and conductance and CT) co-located on chromosome II, in the vicinity of a possible candidate gene-a receptor-like protein kinase found in the syntenic interval of M. truncatula chromosome IV. A ribose-phosphate pyrophosphokinase from M. truncatula chromosome V, postulated as a possible candidate gene for the QTL for CTd, was found some distance away in the same chromosome. These results demonstrate that genomic information from M. truncatula can successfully be translated to the faba bean genome.

“…Recently, high density linkage maps for faba bean have been developed and linked markers have been identified for a number of traits (Torres et al 2010;Cruz-Izquierdo et al 2012;Satovic et al 2013;Kaur et al 2014;Sallam et al 2016), but only two studies have detected quantitative trait loci (QTLs) for flowering time in faba bean. Cruz-Izquierdo et al (2012) detected five QTLs for days to flower in a Vf6 × Vf27 RIL population.…”
