Morphological and physiological seed characteristics of the hyacinth bean (Lablab purpureus) were investigated in a set of 18 different germplasm accessions, from wild over semi-domesticated forms to landraces and current cultivars. The objective of this study was to improve the understanding of the domestication of this tropical legume crop. Wild accessions were easily distinguished by morphological characters, such as small, greyish-brown, mottled seeds. Cultivated or semi-domesticated forms… 
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.
Survey, collection and seed morphometric characterization of French bean (Phaseolus vulgaris L.) landraces of Himachal Pradesh
The study would prove a basic primary step in germplasm recognisition activity for future breeding programmes and will project the local available genetic footprints to entire agro associated enterprises for necessary consideration.
Testing the Effects of a Regionalized Seed Production on the Germination Behavior of Wild Plant Species
This study tested the germination behavior of Plantago lanceolata and Lotus corniculatus, two species frequently used in re-vegetation and found that cultivated varieties from SSP germinated significantly faster and had a higher total germination for both species.
The evidence indicates that the timescale of this evolution was considerably longer than previously supposed, raising questions about the mode of human mediated selection pressure and increasing the importance of the role of pre-domestication cultivation.
Ex situ cultivation entails high risk of seed dormancy loss on short‐lived wild plant species
Dormancy loss is a common phenomenon in ex situ collections of short-lived wild plant species, and effective dormancy breaking and temporal distribution of seedling plantation during propagation should be incorporated in restoration and reintroduction protocols to minimize unwanted changes in seed traits.
Cultivation and Hybridization Alter the Germination Behavior of Native Plants Used in Revegetation and Restoration
It is found that hybrids of cultivated varieties and wild relatives germinate faster and more abundant than the wilds and the long-term survival probabilities of local populations may be altered.
Characterization of Lablab purpureus Regarding Drought Tolerance, Trypsin Inhibitor Activity and Cyanogenic Potential for Selection in Breeding Programmes
This study recommends as selection criteria of the best genotypes for future breeding programmes a combination of at least two, better three, independent methods for the determination of drought effects on L. purpureus and the chemical analysis of compounds which are important for the nutritional value.
The eUects of cultivation and hybridization on life-history traits of native plant species used in re-vegetation
Native plants are increasingly used for re-vegetation and restoration. These plants are cultivated for several generations at plant nurseries and often they are of unknown provenance. Therefore,
Plant populations of three threatened species experience rapid evolution under ex situ cultivation
All three species have rapidly differentiated between wild and ex situ origins and that effects of relaxed selection, genetic drift, inbreeding depression and adaptation to cultivation conditions in the botanic garden may have played a role in population differentiation, which may be unfavourable for reintroduction into nature.
Conditional Seed Dormancy Helps Silene hicesiae Brullo & Signor. Overcome Stressful Mediterranean Summer Conditions
This study focused on the germination behavior of Silene hicesiae Brullo & Signor, a narrow endemic species to Panarea and Alicudi, as well as one of the 50 most threatened Mediterranean island plants, and identified the latter as a suitable seed source for sustainable in situ reinforcement actions.


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.
Lablab purpureus (L.) Sweet – diversity, potential use and determination of a core collection of this multi-purpose tropical legume
The vast range in plant types supported the view that lablab has the capacity to be a multi-purpose legume for both commercial and smallholder agriculture and provided a sound basis for future plant breeding and agronomic studies with this important tropical legume.
Variation in the rate of hard seed breakdown of twelve tropical legumes in response to two temperature regimes in the laboratory
There was considerable variation in threshold temperature and breakdown rates between seed lots of the same cultivar or accession and between species, which indicates that caution must be used before extrapolating the results to the field and to different climatic and/or management environments.

Appropriate germplasm facilitates new interest in neglected crops – the case of Lablab purpureus in the Limpopo Province , South Africa
In many crops, only limited variability is commercially used. This is particularly the case in underutilized crops. On the other hand, lines/cultivars used commercially depend on seed availability,
