“…The magnitude of micronutrients in the present study was substantially higher than those reported by Kumari et al . (2022); thereby, indicating the availability of superior germplasm in our genepool. Differences in micronutrient contents in pods are a function of a gamut of codependent metabolic processes, comprising nutrient uptake dynamics and nutrient partioning (Maganti et al ., 2020).…”

“…Practically, this means better parental heterosis (superior performance of hybrids over parents), where higher values for traits like micronutrients concentration indicate superior parents. Selection of identified genotypes, from different clusters based on desirable traits, as parent in future breeding programme may generate new recombinants with improved heterosis (Kumari et al ., 2022).…”

Exploring the nutritional potential of underutilized legumes such as Dolichos bean (Lablab purpureus L.) is of great significance, particularly, in view of accomplishing the United Nation's Sustainable Development Goal number two, which emphasizes on improving food and nutrition security by 2030. A thorough understanding of genetic variability is crucial for developing biofortified cultivars of Dolichos bean. In this study, the Dolichos bean genotypes represented by pole and bush types (28 bush and 19 pole types) were assessed for genetic variability for Cu, Mn, Fe and Zn contents. Pole type genotypes had higher average contents for all micronutrients except manganese. Among micronutrients, Cu, Fe, Mn and Zn, content ranged from 10.10–19.95, 77.13–331.93, 22.78–46.40 and 42.03–102.85 mg kg−1 in pole type, and 8.2–18.5, 50.8–99.3, 25.65–53.25 and 37.15–63.25 mg kg−1 in bush type beans, respectively. Strong positive correlations between Cu, Fe and Zn concentrations occurred, which indicates the possibility of simultaneous improvement of these nutrients. Pod pigmentation was positively correlated with contents of Fe and Zn. There was an association of micronutrients with yield. The pole genotypes VRSEM-1000, VRDB-01 and VRSEM 109 and bush type genotypes VRBSEM-3, VRBSEM-35 and VRBSEM- 200 are good source of microelements and high yielders. Gene sources with enhanced nutrients may be used as cultivated forms or as input material for breeding nutritionally rich biofortified varieties of bean.

“…Significant positive phenotypic correlations were observed between D50F with DFP, D50F with PH, PL with NPP, APW with NPP, protein with Zn, APW with Vit A, protein with Ca, and P, Vit C with Zn and NPP with pod yield which indicated that when selection is applied for one of these traits, an indirect improvement could be observed in the other traits ( 22 ). The results also indicated that selecting lablab genotypes for APW with NPP should have a positive influence on pod yield and should be considered when selecting for high yielding.…”

“…This suggests that these three criteria are positively correlated and tend to vary together ( 17 ). The considerable diversity observed among these lablab bean genotypes in terms of pod yield and nutritional quality traits suggests that they hold great potential for use in breeding programs and for developing new cross combinations ( 22 , 38 ). This can help to expand the genetic diversity of lablab and ultimately lead to the creation of high-yielding genotypes with superior nutritional value.…”

“…In a similar vein, assessing genetic variants in genotypes or breeding lines offers intriguing opportunities for generating biofortified lablab beans with increased protein content, iron (Fe), Zn, and other essential minerals. This approach has the potential to improve the nutritional value of lablab beans as well as their contribution to human health ( 22 ).…”

IntroductionMalnutrition continues to be a significant concern at unacceptably high levels globally. There is significant potential for addressing malnutrition of human population through the biofortification of climate-resilient vegetables using strategic breeding strategies. Lablab bean [Lablab purpureus (L.) Sweet], a underutilized nutrient-dense crop holds great potential in this aspect. Despite its advantageous nutritional profile, the production, research, and consumption of lablab bean are currently limited. Addressing these limitations and unlock the nutritional benefits of lablab beans needs to prioritized for fighting malnutrition in local inhabitants on a global scale.Materials and methodsTwenty five genotypes of lablab bean collected through exploration survey in Eastern India and were evaluated in 2020–2021. Among them, the nine highly diverse well adapted genotypes were again evaluated at the experimental farm of ICAR-Research Complex for Eastern Region, Patna, Bihar, India in 2021–2022. Horticultural important traits of lablab bean were recorded by using the minimum descriptors developed by ICAR-NBPGR in New Delhi and biochemical analysis was done by using standard protocols. Genotypic and phenotypic correlation and path coefficient analysis was done used understand relationships, interdependencies, and causal pathways between different traits. The outcome was revalidated by using principal component analysis (PCA).ResultsDescriptive statistics revealed substantial heterogeneity across the traits of lablab bean evaluated. Vitamin A content showed nearly a five-fold variation, Fe ranged from 5.97 to 10.5 mg/100 g, and Vitamin C varied from 4.61 to 9.45 mg/100 g. Earliness and dwarf growth was observed in RCPD-1 (60 cm) and early flowering (41 days). RCPD-3 and RCPD-12 had high pod yield due to their high number of pods and pod weight. Pod yield was significantly correlated with number of pod per plant (NPP) (rg = 0.995) and with average pod weight (APW) (rg = 0.882). A significant positive correlation was also found between protein and Zn content (rg = 0.769). Path coefficient analysis revealed that average pod weight had the most direct positive effect on pod yield, followed by NPP and protein content. The reaction of lablab bean genotypes to collar rot disease was also evaluated and significant differences in disease intensity were observed among the genotypes, with the resistant check RCPD-15 exhibiting the lowest disease intensity.DiscussionThe study highlights the substantial heterogeneity in lablab bean traits, particularly in nutritional components such as vitamin A, iron, and vitamin C concentrations. Early flowering and dwarf growth habit are desirable qualities for lablab bean, and certain genotypes were found to exhibit these traits. Positive correlations, both phenotypic and genotypic, existed among different traits, suggesting the potential for simultaneous improvement. Path coefficient and PCA revealed genotypes with high yield and nutritional traits. Finally, resistant and moderately resistant lablab bean genotypes to collar rot disease were identified. These findings contribute to the selection and breeding strategies for improving lablab bean production and nutritional value.
