Abstract

During the process of varietal development, a large number of new breed-ing lines of soybean (PK-series) generated through hybridization and selection are evaluated each year at this centre and elite ones (about 40) are maintained for further use. A brief report of some of these lines has been published (Ram et al., 1982). A path-coefficient analysis using typical yield components and the physiological parameters of yield, viz. dry matter yield (above ground parts), harvest index and seed yield efficiency, was carried out in 50 soybean genotypes (40 new PK-series lines + 10 parental/check cultivars) evaluated during rainy season 1980.
