Two germplasm collections of Lablab purpureus L. Sweet totalling 249 accessions were grown in the field in Australia and Ethiopia and characterised using a common set of morphological and agronomic (M-A) attributes. Data from each site were analysed separately using multi-variate analysis and a classification constructed for each collection. There was considerable diversity within both collections, especially that maintained in Ethiopia. Time to flowering, seed weight, and plant height were the… 
Evaluating Lablab purpureus (L.) Sweet germplasm to identify short-season accessions suitable for crop and livestock farming systems in southern Africa
In the first of three field evaluations conducted in Limpopo province, South Africa, 33 introduced accessions and three local varieties were evaluated, five accessions were found to be consistently early flowering, high seed yielding and are recommended for further evaluation.
Genetic diversity and structure of landrace of lablab (Lablab purpureus (L.) Sweet) cultivars in Thailand revealed by SSR markers
It is demonstrated that there is moderately low genetic diversity of lablab in Thailand and the west of the country possesses high diversity oflablab.
Population genetic analysis of hyacinth bean (Lablab purpureus (L.) Sweet, Leguminosae) indicates an East African origin and variation in drought tolerance
An East African origin of Lablab is proposed and potential adaptive diversity for future crop breeding attempts is identified, with variation in tolerance to drought recorded, with some lines able to tolerate 14 days without watering.
Pheno-morphological, agronomic and genetic diversity among natural populations of sulla (Hedysarum coronarium L.) collected in Sicily, Italy
A large degree of genetic diversity and variability in pheno-morphological and agronomic traits was shown and the observed variability may be valuable when selecting for H. coronarium varieties suitable for various uses.
Determining Sources of Diversity in Cultivated and Wild Lablab purpureus Related to Provenance of Germplasm by using Amplified Fragment Length Polymorphism
The molecular analysis identified forms that were collected in the wild in India but were genetically placed intermediate between wild and cultivated forms and support the suggested pathway of domestication and distribution of L. purpureus from Africa to Asia.
Changes in seed characteristics during the domestication of the lablab bean (Lablab purpureus (L.) Sweet: Papilionoideae)
Seed characteristics of the lablab bean were investigated in 46 germplasm accessions, from wild through semi-domesticated forms to landraces and current cultivars to improve the understanding of the domestication process in this tropical crop legume.
Evidence for two domestication events of hyacinth bean (Lablab purpureus (L.) Sweet): a comparative analysis of population genetic data
Two domestication events appear to exist in L. purpureus based on results from a recent molecular investigation, which combines findings of eight molecular genetic studies that include about 400 accessions of both wild and cultivated germplasm, thus providing the largest assessment of diversity in Lablab pur Pureus to date.
Morphological and microsatellite characterization of improved Lablab purpureus genotypes
The combination of morphological and DNA-based markers takes advantage of the best features of both marker types which can be beneficial in selection of best Lablab genotypes and in the process integrates the application of molecular markers to legume breeding.
Breeding potential of lablab [Lablab purpureus (L.) Sweet]: a review on characterization and bruchid studies towards improved production and utilization in Africa
A detailed analysis on the characterization of lablab and the information on bruchid resistance vital for breeding farmer-preferred varieties that possess agronomically beneficial traits is provided.
Investigating the diverse potential of a multi-purpose legume, Lablab purpureus (L.) Sweet, for smallholder production in East Africa
Suitability of lablab for grain and biomass production were visualized across Tanzania in a map comparing max temperature thresholds forgrain and biomass against average regional livestock populations, providing a way forward for identifying potential areas for lablab cultivation as a novel means to enhance fodder and pulse production with smallholder farmers.


Genetic diversity and relationships among Lablab purpureus genotypes evaluated using RAPD as markers
A high level of genetic variation in this species was detected but this was mainly restricted to the difference between cultivated and wild forms, and genetic variation among Asian collections was significantly higher than that among African collections.
Evolution of Grain Legumes. V. The Oilseeds
The greatest contrast between the two species is in photoperiod sensitivity; the groundnut is day-neutral while the soyabean is a short-day plant with genotypes varying widely in the day length tolerated without inhibition of flowering.
Evolution of Grain Legumes. II. Old And New World Pulses of Lesser Economic Importance
SUMMARY A consideration of the apparent lack of general success of minor pulse crops can lead to a better appreciation of the factors which have made the major pulses successful. The relevant factors
Compositional dissimilarity as a robust measure of ecological distance
The robustness of quantitative measures of compositional dissimilarity between sites was evaluated using extensive computer simulations of species' abundance patterns over one and two dimensional
Semi‐strong Hybrid Scaling, a new ordination algorithm
A new ordination algorithm called Semi-strong Hybrid Scaling, SHS, uses features of Faith, Minchin & Belbin's Hybrid method in an attempt to provide a better configuration of the sites.
