“…High coefficient of variation in the characters of crops has been attributed to the heterogeneity existing among germplasm accessions of such crops [25]. In agreements with the results of this study where all phenotypic co-efficient of variation (PCV) was higher than genotypic co-efficient of variation (GCV) for all the traits studied, Singh et al [26] who obtained similar results attributed this to the influence of environmental factors on the expression of the characters.…”

“…The high heritability in conjunction with moderate to high genetic advanced obtained for all the studied traits indicate the importance and reliability of these characters for selection. High heritability coupled with moderate genetic advance has been attributed to equal importance of additive and non -additive gene actions [26]. High estimates of heritability have been reported to be one of the major indicators of phenotypic variability in the characters of any crops contributed by additive gene effects [27].…”

Genetic variability which is the basic material for selection and improvement of any crop is fast eroding in pearl millet as natural habitats of wild cultivated species are being destroyed and modern cultivars replacing the traditional cultivars. On this premise collection and characterisation of the crop germplasm was carried to identify elite accession(s) for the crop improvement. Thirty five (35) pearl millet accessions collected from the major cultivated states in Nigeria were evaluated for morphological and yield parameters using a Randomised Complete Block Design (RCBD) with replicate three each. Wide range of significant (P < 0.05) variability was observed in all the morphological characters assessed with different trait been favoured by different genotypes. The highest plant height was recorded in KD-CK-01 (371.85 cm) and the least height in accession NG-ZA-05 with the value of 170.58 cm. Accession NG-ZC-03 had the highest weight of seeds per plot and weight of seeds per hectare with the value of 738.52 g and 1318.78 kg/ha respectively. Phenotypic coefficient of variance was higher than the corresponding genotypic coefficient variance for all the traits studied. Moderate (30-60%) to high (>60%) heritability was obtained among the traits studied while genetic advanced ranged from 21.92 to 127.27. Cluster analysis grouped the accessions into four major clusters based on their morphological similarity; cluster I consisting 14.29% of the genotypes, 17.14% in cluster II, 40.00% in cluster III and 28.57% were clustered in IV. The high variability recorded in the germplasm couple with high heritability and genetic advance in most of the parameters studied, indicate that the accessions and traits could be explored in the crop improvement.

“…In spite of, three selected genotypes G2 (14.26 kg/plot), G7 (13.91 kg/plot) and G5 (13.78 kg/plot) were higher than the check variety G9 (13.64 kg/plot) for total dry yield but two only genotypes were significantly observed. This agrees with Singh et al (2018) who found significant difference among seven hybrids and their seventeen parents of pearl millet for 28 morphological and yield characters.…”

“…To success the improvement of crop depends on the reach of characterized germplasm for diverse traits available for desired cultivars in program of breeding where fodder millet has wide genetic diversity which is of little value unless it is characterized, estimated and classification properly to enhance its exploitation in crop improvement. To exploit effectively the available genetic diversity, the material must be properly characterized and catalogued (Singh et al 2018).…”

The presence of divergence in germplasm and its efficient utilization is essential for successful improvement of any fodder crop. During 2020-2021 summer seasons at Sids ARS. A total of ten pearl millet genotypes were grown with RCB design in three replicates to determine genetic variability, genotypic and phenotypic coefficients of variations, heritability, genetic advance and degree of linkage among various traits based on yield component, forage yield, and quality traits using cluster and principal components analysis (PCA). Results of combined analysis revealed significant differences among two years, genotypes and interaction of year x gen. for most traits. The genotypes (G2, G5 and G7) are promising and can be recommended in breeding programs due to revealing the highest yield components, forage yield, and quality values.The largest estimates of genotypic and phenotypic coefficients, high value of heritability connected with high value of genetic advance percent as mean were observed for most traits, indicating to existence of genetic variation beside efficient possibility selection for these traits. Results of cluster dendrogram analysis exposed a great genetic divergence among the tested genotypes, classifying them into 4 sub-clusters. The study detected six principal components (PCs) with Eigen values higher than 1.00 which, accounted for 90.027 % of the total variation for discriminating the 10-millet genotypes based on the studied traits. Therefore, these traits can be applied to selection criteria for yield improvement and determined appropriate genetic resource for efficient in pearl millet breeding program.

“…These results are in line with findings of Bhasker et al, (2017) and Patel et al, (2019) for plant height, panicle length and dry fodder yield per plant; Talawar et al, (2017) and Kaushik et al, (2018) for 1000 grain weight and grain yield per plant; Bika and Shekawat (2015) and Singh et al, (2018) for panicle girth and green fodder yield per plant; Dehinwal et al, (2016) for panicle weight.…”
