Barnyard millet is an under-utilized minor millet which is being popularized nowadays bestowing with high nutrient content in grains. Fourty genotypes were evaluated in high altitude region to determine the correlation and path coefficient among the yield and yield attributing traits. Correlation analysis evinced that grain yield per plant had positive significant correlation with agro-morphological traits viz., plant height, days to flowering, days to maturity, number of nodes, stem diameter, length of flag leaf, width of flag leaf, length of inflorescence, width of inflorescence, length of lower racemes, number of racemes and thousand grain weight. The trait length of peduncle alone expressed negative significance with grain yield. The path coefficient estimation indicated that stem diameter had exposed high magnitude of direct effect on grain yield. Henceforth, the direct selection based on the flawless relationship between grain yield and these traits would benefit in selecting high yielding genotypes.

Nutritionally, Barnyard millet is an important crop, it is probably originated in central Asia and spread from central Asia to Europe and America. Climate change will alert an extra constrains as many parts of the country are becoming drier with increasingly severe weather patterns. Developing better barnyard millet cultivars is always placing as an important strategy in crop improvement. This study was focused to evaluate the phenotypic diversity and stability of barnyard millet germplasm for yield and its attributing traits. Diversity as revealed by D 2 analysis indicated that the trait grain yield had contributed maximum towards the diversity followed by days to maturity. The accessions M5P1, M36P1 and M37P1 exhibited the highest mean values for grain yield per plant, but no significance difference was found comparing checks. Stability analysis revealed that none of the accessions were showed stable performance, indicated that influence of environmental factors played a major role.

Among nutri-cereals, now-a-days, barnyard millet getting popular among the public for its rich nutritional and cooking qualities. A total of forty genotypes were evaluated in three different environments to study the genetic diversity using Principal Component Analysis.Foremost three components contributed 85.65 % of the total multivariable differences. Germplasm projection delivered four main groups on first two canonical components. Genotypes splitting were on the basis of trait performance. Majority of the traits had explained low to moderate values with negative loadings to PC1, PC2 and PC3 except few traits like thousand grain weight and number of basal tillers, which had positive loadings with high values. Loadings bi-plots of PC1-PC2 and PC1-PC3, classified the groups into two major categories, consisting of late matured-high yielding genotypes on left side and early matured-low to medium yielding genotypes on right side of scattering.
