Abstract:
A total of 39 genotypes of mungbean were taken for analysis in the present study for statistical analysis related quantitative traits. To investigate the morphological characterization among these mungbean genotypes using quantitative traits. The present study was carried out at the BSP Soybean unit, College of Agriculture, JNKVV, Jabalpur, Madhya Pradesh. The genotypes were sown in six rows of with 30 X 10 cm spacing under RCBD design with three replications. The seed sowing was made in the month of November 2021. Morphological characterization was done for ten characters and it was noted that for anthocyanin pigmentation thirty-five genotypes showed presence of pigmentation and in remaining four genotypes were absent for this trait, stem colour, one genotype of mungbean (PKVAM 4) showed purple colour stem, while remaining 38 genotypes showed green stem colour, stem pubescence, two genotypes (TJM 155 and TJM 143) showed pubescence on stem and the remaining 37 genotypes absence for this trait, two genotypes (MH 421and TJM 137) of mungbean showed deltoid leaf shape while remaining thirty-seven genotypes showed ovate leaf shape for this character, five genotype of mungbean showed green colour leaves, while remaining thirty-four genotypes showed dark green colour of leaves, thirty-seven genotypes of mungbean showed green colour leaf vein, while remaining two genotypes (Pusa-Vishal and GAM 5) were greenish purple leaf vein, thirty-eight mungbean genotypes showed green colour of petioles whereas, only one genotype (GAM 5) was green with purple splashes in petioles, out of total, thirty-eight genotypes of mungbean showed green colour of premature pod, while only one genotype (Yellow mung) was green with pigmented nature of premature pod colour, pubescence on pod was recorded in this investigation; it was noted that thirty-eight genotypes showed pubescence on the pod and the rest one genotype (TJM-235) was free of pubescence on pod and thirty-eight genotypes showed pod position intermediate and the remaining one-genotype (Pusa-Vishal) pod position was above the plant canopy. These identified diverse morphological breeding traits is present in very few of the genotypes included in this investigation. The identified diverse breeding traits may be employed in hybridization programme in developing diverse morphology based genotype/varieties so, that the genotypes with unique morphological identity will easily be identified in between the group of varieties. Maintenance of the varietal purity has been one of the major challenges in the research area and it is very important to check whether the genotypes or treatments or population under study are satisfying the requirements of morphological characterization protocols which includes distinctness, uniformity and stability. These unique identities will be helpful as an important morphological trait to distinguish one variety from the other in seed production programme. By the diverse identity of the varieties, genetic purity maintenance will be very easy and may stay in seed production chain for a very long time.
