Abstract

Forty three germplasm accessions along with six checks, analyzed for morphological characterization, variability studies during kharif 2022-23, in alpha lattice design. Total twenty seven biometrical and nonbiometrical characters were evaluated on each accession at different growth stages. Germplasm was classified on the basis of fifteen morphological characters viz., anthocyanin coloration of hypocotyl, plant branching pattern, plant growth habit, stem: colour, leaf: shape, pubescence on lower surface of leaf, flower: colour of base of petal (standard), pattern of streaks on petal, pod: colour, pod: pubescence, pod: waxiness, pod: surface stickiness, seed: colour, seed: colour pattern and seed: shape. Variability analysis was carried out among twelve quantitative observations viz., days to 50% flowering, numbers of flowers at 50% flowering, days to maturity, plant height (cm), number of branches per plant, number of pods per plant, number of pods per cluster, number of seeds per pod, 100 seed weight (g), days to 1st pod formation, days to 100% pod formation, seed yield per plant (g). Variability studies revealed the germplasm used in current study has ample amount of variability present and can be used as donor in pigeonpea improvement programme.

Conclusion

The germplasm used in current study has ample amount of variability present and can be used as donor inpigeonpea improvement programme. The genotypes having unique traits such as orange flower color (RP-93, RPS 2015-13, RPS 2015-21, RPS 2015-27), medium streak patter on flower petal (RP-179, RP-232), obovate leaf shape (RPS 2015-34, RPS 2015-1), grey seed color (RPS 2015-1) and elongate seed shape (ICP-6996) can be used as morphological markers trait in pigeonpea breeding programmes. Analysis of variance revealed that mean square due to genotypes were found significant at 1% and 5% level for all the traits, indicating variability present in the material studied. The high genotypic coefficient of variation and genotypic coefficient of variation was recorded for number of flowers at 50% flowering followed by number of branches per plant, seed yield per plant, number of pods per plant. Whereas lowest genotypic coefficient of variation and genotypic coefficient of variation was recorded for days to 50% flowering. The phenotypic coefficient of variation higher than genotypic coefficient of variation. This indicated that apparent variation is due to genotype but also due to influence of environment.
