Abstract
The present investigation entitled “Genetic variability and path analysis is
soybean [Glycine max (L.) Merrill]” was carried out with one ninety eight
germplasm along with three checks to study about seed yield, its components and
quality characters. These germplasm were planted in augmented randomized block
design with 6 blocks during Kharif, 2003 at experimental farm, Department of Plant
Breeding and Genetics, RCA, Udaipur.
Observations were recorded for 10 characters viz., days to flowering, plant height,
branches per plant, pods per plant, 100-seed weight, seed yield per plant,
biological yield per plant, harvest index, seed protein and oil content. The
observations were recorded on twenty randomly selected plants in each plot for all
the characters except days to flowering and data so obtained were subjected to
analysis of variance, estimation of variability parameters, correlations and path
coefficient analysis.
Analysis of variance revealed significant difference among treatments, checks
and germplasm for all the characters indicating presence of sufficient variability in the
material under study.
GCV was recorded high for branches per plant, pods per plant and biological
yield per plant. High values of heritability were recorded for pods per plant, plant
height and biological yield per plant. Genetic gain was high for branches per plant,
biological yield per plant and pods per plant.
