“…It is considered as a good source of protein, carbohydrates and energy (Bravo et al, 1998). It is tolerant to drought (Bhardwaj and Yadav, 2012), salinity (Reddy et al, 1998) and heavy metal stresses (Reddy et al, 2005). In addition, due to its genome plasticity the crop is suitable for its cultivation in low input lands (Priyanka, et al, 2019).…”

The present experiment was carried out to estimate the genetic diversity by cluster and Principal Component analyses for seven yield and yield attributing traits in 50 horsegram germplasm accessions and two checks during the late kharif, 2019. In correlation analysis, the grain yield was positively and significantly associated with test weight and number of pods which suggested the possibilities of improving grain yield by simultaneous improvement of these traits. Using cluster analysis, the accessions were grouped into five clusters. Based on the average cluster mean, the first cluster had high mean values for grain yield, the number of pods, test weight and plant height. The results of PCA revealed that, PC1, PC2, PC3 having eigenvalue greater than 1 contributed to the total variability of 82.69 per cent. Horsegram genetic improvement is receiving less attention from researchers across the globe. Using the results of this study, there is a tremendous space for genetic enhancement in grain yield of horsegram.

“…is a member of leguminous family adapted to wide range of environmental regimes. It is a selfpollinated crop, having tolerance to drought (Bhardwaj and Yadav, 2012), salinity (Reddy et al, 1998) and heavy metal stress (Reddy et al, 2005). The seeds are enriched with a protein content of 18.5% -28.5% (Savithramma and Shambulingappa, 1996), carbohydrates (50% to 70%), minerals, iron, molybdenum (Bravo et al, 1999) and vitamins (Sodani et al, 2004).…”

Genetic relatedness studies using 12 quantitative traits on 252 genotypes in horsegram revealed wide spectrum of variability for yield components. The genotypes were grouped into 25 clusters based on estimates of D2 statistic. Cluster I had the largest number with 83 genotypes followed by cluster II (77 genotypes), cluster IV (33 genotypes) and cluster III (30 genotypes). On the contrary, 20 solitary clusters from cluster V to XXV were formed except cluster XIV (9 genotypes) which could be given priority for specific trait improvement. Cluster XXI recorded the highest mean value for single plant yield (65.51 g). The intra and inter cluster distance was varying in magnitude indicating the presence of larger genetic diversity among accessions. The highest intra cluster distance was noticed in cluster XIV (23.63) followed by cluster IV (22.37). Maximum inter cluster distance was observed between solitary clusters viz., cluster XXI and XVII followed by cluster XXI and XV and cluster XXI and VII. These clusters would offer superior segregants when employed in hybridization programme.

“…This raises the question as to whether cultivation of this crop was formerly more widespread in Southeast Asia. (Kachroo and Arif 1970;Yadav 1992;Sundararaj and Thulasidas 1993;Lokeshwar 1997) Recent investigations undertaken, mainly by Indian researchers, have examined the genetic variability in order to improve this crop (Bolbhat and Dhumal 2009;Dikshit et al 2014;Dhumal and Bolbhat 2012;Bhardwaj et al 2010Bhardwaj et al , 20122013a, b;Prakash et al 2010;Varma et al 2013;Sharma et al 2015), particularly in regards to the genetic and biochemical properties of drought-tolerant variants in response to climate change and rapid population growth in India (Bhardwaj et al 2013a;Bhardwaj and Yadav 2012;Morris et al 2013;Reddy et al 1998Reddy et al , 2008. Nevertheless, an evolutionary and historical perspective on this crop remains to be better developed.…”

Horsegram has been an important crop since the beginning of agriculture in many parts of South Asia. Despite horsegram's beneficial properties as a hardy, multi-functional crop, it is still regarded as a food of the poor, particularly in southern India. Mistakenly regarded as a minor crop, largely due to entrenched biases against this under-utilised crop, horsegram has received far less research than other pulses of higher status. The present study provides an updated analysis of evidence for horsegram's origins, based on archaeological evidence, historical linguistics, and herbarium collections of probable wild populations. Our survey of herbarium specimens provides an updated map of the probable range of the wild progenitor. A large database of modern reference material provides an updated baseline for distinguishing wild and domesticated seeds, while an extensive dataset of archaeological seed measurements provides evidence for regional trends towards larger seed size, indicating domestication. Separate trends towards domestication are identified for northwestern India around 4000 BP, and for the Indian Peninsula around 3500 BP, suggesting at least two separate domestications. This synthesis provides a new baseline for further germplasm sampling, especially of wild populations, and further archaeobotanical data collection.
