“…The present investigation was carried out at Farming Systems Research Station, Sadanandapuram, located at latitude 8°58' N, longitude 76°48' E and at an altitude of 76 m above mean sea level. The thirty genotypes of horse gram in a randomized block design replicated thrice, employed in the investigation of Lalithambika et al [1] formed the material of this study. The crop was raised using the KAU [7] "Package of Practices Recommendations Crops 2016" guideline.…”

A field experiment was conducted to evaluate the correlation and path analysis in thirty horse gram germplasm lines under moisture-stressed conditions using various selected characters. The association studies revealed a significant positive correlation of seed yield with relative water content, number of pods per plant, number of seeds per pod, total chlorophyll content, harvest index, proline content, root dry weight, root length and leaf area index. While days to 50% flowering, days to maturity, plant height and number of primary branches showed a significant negative correlation with yield. Path coefficient analysis revealed a high positive direct effect of the number of pods per plant on seed yield and the number of seeds per pod recorded exhibited the highest indirect effect on seed yield via the number of pods per plant under moisture stress conditions in horse gram. So, selection based on the number of pods per plant will be more beneficial under water stress conditions. The exploitation of genetic diversity is key to a successful breeding program. The principal component analysis using selected fifteen characters revealed the existence of adequate genetic variability among genotypes under study. First four principal components accounted for a cumulative variance of 82.47%. The principal component analysis (PCA) biplot revealed genotypes viz. IC22785, IC392329, HG 26L and IC20753 to highly diverse and these genotypes may be employed for enhancement of various traits in horse gram.

“…Also, it has become essential to create cultivars capable of providing maximum yield in environments with drought stress [21]. Superior genotypes of horsegram with high yield under drought stress tolerance of Kerala's south-central laterite region and the degree of diversity among the genotypes was identi ed [22]. Agrarian traits controlling the drought stress tolerance are polygenic in nature and are quantitatively inherited [23].…”

Horsegram (Macrotyloma uni orum (Lam.) Verdc.) is a drought hardy legume which can be grown in varied soil and temperature regimes. Though it has numerous, nutritive and medicinal bene ts. However, it still lags behind other legumes in terms of genetic improvement. This crop is mostly cultivated on marginal and drought prone area thus genetics of drought stress tolerance were understood by studying the various drought parameters. To get insight, quantitative trait loci for drought tolerant traits were identi ed using an intraspeci c mapping population of 162 F 8 recombinant inbred lines derived from a cross between HPKM249 and HPK4. The linkage map already developed was used along with the phenotypic data for biochemical and physiological parameters to identify genomic regions which are linked to drought tolerance. In the study total of seven QTLs were identi ed for ten different drought related traits. One QTL for malondialdehyde content on linkage group 2, two QTLs for root length on linkage group 3 & 9, one QTL each for proline and chlorophyll content under drought stress on linkage group 4, one QTL each for root dry weight and root fresh weight on linkage group 5 were identi ed using composite interval mapping. The identi ed QTLs will be utilized in marker assisted breeding and increase our understanding on the physiology of drought stress tolerance.

“…Interest in functional foods and nutraceuticals containing bioactive substances has increased in recent years due to their various health benets. [9][10][11] Horse gram is highly nutritious, containing protein (17.9-25.3%), carbohydrates (51.9-60.9%), essential amino acids, low lipid content (0.58-2.06%), minerals, and vitamins, 12 as well as bioactive compounds like phenolic acids, avonoids, and tannins. Horse gram exhibits high emulsication activity and stability.…”
