Extraction of core sample collection and selection of parents from indigenous and exotic germplasm of soybean [Glycine max (L.) Merrill]

Published on

Five hundred and twelve soybean germplasm accessions
were evaluated for 11 agronomical traits and characterized
with respect to 18 morphological characters. A wellrepresented sample collection was derived based on the
agronomical data. Through principal component analysis
it was inferred that number of clusters per plant, total
number of pods per plant, total dry matter accumulation,
seed yield per plant and maturity traits contributed
maximum towards the genetic diversity of the accessions
in base and also in sample collection. With respect to
morphological traits, hypocotyl anthocyanin pigmentation,
seed shattering, shape of lateral leaflet, flower colour and
seed coat colour were highest contributors to genetic
divergence. From the sample collections after studying
the oil and protein content, TNAU S 55, JS (SH) 89-49, EC
2572, CO 2, EC 799 and JS 92-4 were identified as potential
parents to get good segregants.
