Abstract

An experiment was conducted to identify the diverse morphological breeding lines. A total of Fifty-two germplasm lines were characterized morphologically as per DUS guidelines, and Shannon’s diversity indices (mean value=0.612) were estimated using Microsoft Excel. The results revealed that maximum variability and diversity were present in foliage color, pod intensity of green color, seed cotyledon color and plant height. Minimum variability was reported for stem anthocyanin colouration, seed testa mottling, leaf axial color and flower standard petal color. The traits of foliage waxy bloom and stipule type were present in all the genotypes. Stem anthocyanin coloration, seed testa mottling, flower standard petal color, and leaf axial color were unique traits and were reported in only a few of the genotypes. It may be concluded that these traits would be considered diverse morphological traits during the selection of lines in segregating generations for the development of pea lines /Variety.

Keywords: Morphological characterization, pea, DUS guideline, shannon’s diversity indices, segregating generations
