“…4). Chaudhary et al (2021), Rupika and Bapu (2014) and Yohane et al (2020) also reported yellow flower colour as prominent in pigeonpea. With regard to the number of seeds per pod, three seeds per pod were observed in 17 genotypes (30.91 %) and 38 genotypes (69.09 %) had four seeds per pod.…”

The DUS test is an important tool for cataloguing the genotypes and utilization of variants in the crop improvement programme. In the present investigation, a total of 55 early duration pigeonpea genotypes were categorized by descriptors and cluster analysis for 21 agro morphological traits. Wide variations were observed in the characters viz., flower colour, a pattern of streaks, pod colour, seed colour, seed shape and size and no much variation was observed for the remaining traits. The traits viz., earliness and prominent type of pod constriction were identified in all the genotypes. The genotypes were partitioned into six clusters. Cluster I encompass 32 genotypes; cluster II consists of seven genotypes; four genotypes each were placed in clusters III and V; clusters IV and VI comprised of five and three genotypes, respectively. In the present study, the DUS descriptors and the variation observed in the early duration pigeonpea genotypes will form the basis for designing the pigeonpea improvement programme.

“…Pod pubescence was present in all 70 genotypes. Sivabharathi et al, Chaudhary et al(2021) also reported the presence of pod pubescence in all 236 pigeonpea genotypes. Small seeds were found in 30 genotypes and weighed less than 10 g per 100 seeds, medium seeds were found in 39 genotypes and weighed 10.1 g to 13.0 g, and large seeds were found in one genotype and weighed 14.12 g (i.e., >13.0 g) viz., MACS 1254.…”

A total of 70 soybean genotypes from the Ramaiah gene bank including five checks were evaluated for 14 qualitative and four quantitative traits based on DUS guidelines given by PPV& FR. Sixty-five genotypes and five check varieties were subjected to cluster analysis and were grouped into four major clusters with an average similarity of 77%. Cluster I consisted of 41 genotypes, cluster II had 15 genotypes, cluster III had nine genotypes and cluster IV had five genotypes. The study revealed an association between anthocyanin pigmentation in hypocotyl and flower colour. MACS 1254 was identified as the only genotype with a yellow green seed coat among 70 genotypes. According to the DUS, two genotypes viz., JS 76-1194 and JS (SH) 91-93 showed a lanceolate leaf shape. The distinct genotypes identified in the present study could be used in the breeding programme for the improvement of soybean.

As study indicated chararacterization of crops based on agro morphological traits are important for breeding to select the best quality accession in the field gene bank. 34 chickpea accessions were characterized based on agro morphological traits. All studied accessions were characterized by absences of plant pigmentation and most accessions were characterized by erect plant growth type and pink flowering color. Accessions were characterized by medium pod length and angular ram’s seed shape. Majority of accessions were characterized by rough seed textures and brown to reddish brown seed color. Most accessions were characterized by medium seed size and early flowering days. The highest coefficients of variation were observed for Days to 50% flowering (0.57%) and least coefficient of variation (0.04) for Plant height. 32 accessions were flowering lately than the check varieties and 25 accessions were more lately matured than the check varieties. Twenty accessions produced more primary branches than the check varieties. 24 accessions produced higher pods per plant compared to the check varieties. Cluster I consisted of eleven accessions and cluster II consisted of eighteen accessions and also cluster III consisted of five accessions. The intra cluster distance ranged from 474.48 to 953.36. There was significantly strong positive correlation observed between days to 75% maturity with plant height(r=1.00) while weak and negative correlation were observed between days to 50% flowering days with secondary branch but no correlation secondary branch with 100 seed weight.
