Analysis of variance for 11 traits under investigation revealed significant variability among the genotypes. This indicated an extensive range of genetic variability existed among the genotypes of blackgram. On the basis of higher mean performance than general mean, genotype PU-19 reported higher seed yield/plant along with higher number of seeds/pod, number of clusters/plant, number of pods/ cluster. Hence, recommended for the enhancement of area under this variety particular in rainfed ecology. On pooled basis seed yield/plant had significant correlation with all yield contributors except plant height. Number of seeds/pod, number of clusters/plant, number of pods/cluster and seed yield/plant signified high heritability as well as high genetic advance as percentage of mean indicated the presence of additive gene action, while plant height and number of pods/ plant exhibited modest heritability as well as modest genetic advance as percentage of mean. Consequently, suggesting the presence of additive gene action and phenotypic selection for such traits may be useful in the future of blackgram improvement programs.

“…These genotypes are desirable for rainfed conditions due to early maturity. Alike results were also showed by Kumar et al (2021) and Kumar et al (2022) for days to maturity in urdbean and mungbean under rainfed conditions, respectively.…”

“…Plant height, 100-seed weight, days to maturity and reproductive period contributed much for diversity (Konda et al, 2007); Geetanjali et al (2015) reported that days to 50 per cent flowering, days to maturity and plant height contributed much for the diversity. While, Kumar et al (2018) reported that plant height, days to 50 per cent flowering and single plant yield contributed much for the diversity in blackgram.…”

Background: The choice of parents is a very crucial step which decides the success or failure of any plant breeding programme. Using the diversity analysis, parents with high diversity can be chosen to generate high magnitude of useful variability. Therefore, the present investigation was planned to assess the genetic divergence among 100 genotypes of blackgram for identification of diverse genotypes for their utilization in breeding programme.Methods: The material for study consisted of 100 blackgram genotypes collected from different sources and were evaluated at ARS, Bidar during kharif-2018. The experimental trial was laid out in lattice design (10×10) with two replications. Observations on 12 quantitative characters. The genetic divergence was assessed by using Mahalanobis’ generalized distance (D2) and clustering of genotypes by Tocher’s method.Result: The relative contribution of each character to the total diversity was different and contribution of days to maturity was maximum (66.04%) followed by reproductive period (15.86%). The genotypes were grouped into nine clusters by Tocher’s method. The cluster pattern revealed that, cluster II was the largest with 28 genotypes followed by cluster I (26), V (19), III (11), IV (10) and VII (3) and remaining viz., VI, VIII and IX were solitary clusters. The inter-cluster distance ranged from 15.50 to 514.44 indicating high magnitude of diversity. The genotypes belonging to cluster III viz., BDU-20, BDU-3-20, BDU-68, TRCRU-22 possessed desirable traits like earliness and higher seed size and genotypes of cluster IV viz., BDU-9, BDU-10, LBG-752 possessed traits like higher reproductive period, maturity and high seed yield were identified as diverse. These genotypes could be involved in recombination breeding programme for the improvement productivity in blackgram.

“…Blackgram (Mash bean) is one of the important pulse crops belongs to the Papilionaceae family (Mohanlal et al 2021). The crop has genetic diversity for its growth and yield (Kumar et al 2021;Priya et al 2021). Legume plants are efficient in biological nitrogen fixation (BNF).…”

Background: Nickel can act as micronutrient essential for nitrogen fixation in legume crops or it can cause toxicity when present in high concentration. Rhizospheric supplement of Nickel be at a dose not beyond its beneficial level. Methods: An experiment was conducted for mash bean genotypes to evaluate the toxic level of Nickel concentrations. Seeds of four genotypes were sown in earthen pots filled with homogenized loamy soil. Nickel was added as its chloride salt solutions at the age of twenty days @ 15.0, 30.0, 45.0, 60.0, 75.0 and 90.0 mg kg-1 soil. Yield plant-1 and its contributing factors were recorded at physiological maturity of crop. Result: At low concentration, Nickel appeared to be non toxic and high doses reduced yield attributes. The lowest significantly effective dose which affected the parameters was 45 mg kg-1 except for number of legumes plant-1 for which same was true at 60 mg kg-1. While, the most effective dose was 45 mg kg-1 for each attributes. The observations were excluded from the ongoing trend when 15 mg kg-1 Nickel reflected positive role. Of the genotypes, MASH 80 was the least productive while MASH 88 was the most productive. In terms of grain numbers, MASH 97 was the least sensitive.
