“…by hybridization programme to exploit hybridity. The results are on par with the results of Shankar et al (2019b & 2019a) [12] , Anamika and Amaravati (2018) [1] for SCMR and Meghala et al (2019) [8] for SCMR and oil content. However, moderate heritability alongside with moderate GAM was noticed for leaf proteins (29.35, 6.00%) indicating this trait is governed by both additive and non-additive gene action with moderate influence of environment in its inheritance.…”

“…Em values showed that the variation around the mean value was very low for root to shoot ratio (0.47 ± 0.01) followed by leaf proteins (0.73 ± 0.05) whereas, it was high for seed phenols (643.89 ± 15.78) followed by leaf phenols (369.50 ± 10.24) indicating that root to shoot ratio and leaf proteins were most stable indices and was useful to selections across genotypes.

“…In this study, except relative water content (9.51%), all the traits exhibited high genetic advance over mean. Similar results published by Shankar et al (2019bShankar et al ( & 2019a [12] The heritability estimate gives an idea about the proportion of observed variability, which is attributed to genetic difference. Heritability in broad sense may play greater role about information of relative value of selection, but Johnson et al (1955) [10] had shown that heritability and genetic advance should be jointly considered for reliable conclusion.…”

“…In this study, heritability in broad sense was found to be high for all the characters except for leaf proteins (58.90%) suggesting the important role of genetic constitution in the expression of the character and such traits are considered to be dependent from breeding point of view. Similar results published by Shankar et al (2019b & 2019a) [12] ~ 907 ~ Journal of Pharmacognosy and Phytochemistry http://www.phytojournal.com [12] , Meghala (2019) [8] , Manjubhargavi et al, (2018) [11] , Anamika and Amaravati (2018) [1] . From the above heritability estimates, it is clear that all the traits under study in normal moisture environment are less influenced by the environmental factors and are controlled by additive gene effect and selection will be effective for these characters.…”

Crop: Groundnut is one of the proteins and oil-producing legume crop of arid and semi-arid regions of the world.The Objective of the study: To estimate the genotypic coefficient of variation, heritability and genetic advance for physio-biochemical and root related traits among groundnut germplasm under the irrigated condition and To put guideline to establish a breeding program for developing genotype (s) with higher yield using suitable selection criteria through genetic variability studies. Research location and season:The College of Horticulture, Hiriyur during rabi 2016-17. Experimental design: Randomized complete block design with two replications. Methodology: forty groundnut genotypes including ICRISAT based advanced breeding lines and existed cultivars were evaluated under field condition. The crop was taken care of as per the standard recommended package of practices. Data was recorded on physio-biochemical and root related parameters at different stages of crop growth. The resulted mean data was subjected to statistical analysis using Genstat 14.1 software. Results: Results revealed highly significant differences for all the traits under study indicating the presence of genetic variation among the genotypes. The characters like MSI (99.89 & 112.99%), leaf phenols (99.63 & 74.26%), seed phenols (99.06 & 73.05%) and root to shoot ratio (86.19 & 21.04%) exhibited high heritability coupled with high genetic advance over mean. Conclusion:It can be concluded that the presence of additive gene action in governing these traits. Thus, there is ample scope for improving these characters based on the direct selection from the genetic stock studied which means if these characters are subjected to any selection scheme for exploiting fixable genetic variance; a widely adopted genotype can be developed.

“…Analysis of variance revealed signi cant differences among genotypes for all the characters studied at both 5% and 1% level except for zinc content which is signi cant at 5% level only (Table 1). Similar reports of signi cance for ANOVA were given for yield and quality traits in groundnut by Shankar et al (2019) and Chandrasekhara et al (2020). Presence of high phenotypic variability is important for the traits under a study, to identify genomic/functional variations if any at the targeted traits and thereby to tag a trait at molecular level.…”

Background The progress in tagging/mapping of genes in crops like Arabidopsis, rice, maize etc. is far ahead when compared to the major legume crops viz. groundnut, chickpea, redgram, greengram, soyabean etc., even in the post release period of legume genome sequence databases. This can be attributed mainly to low level of available molecular genetic diversity in these crops. Methods The study of transferability of Rice yield gene tagged markers to Peanut was carried out by employing17 diverse groundnut genotypes. ANOVA revealed significant differences for six yield and seven seed quality traits studied which indicates availability of ample amount of variability among the genotypes. Molecular analysis was conducted to analyse the transferability of known rice yield, grain size and micronutrient content (Fe and Zn) controlling gene tagged markers (GTMs) to peanut by using 45 GTMsthat targets 24 known functional genes. Results Of 45 markers, 31 (76%) were transferable to peanut, denotes very high conservation at functional regions. The extent of amplification of rice GTMs at individual groundnut genotype level was observed from 79.17% for the cultivated varieties (2n = 4x) Nithya Haritha, Greeshma, Prasuna, Kalahasti, Narayani and with a wild genotype, Arachis villosa(2n = 2x) to 91.67% for Dheeraj variety. The analysis on transferable efficiency of individual rice GTM revealed that 17 markers belong to 14 rice genes showed amplification among all the 17groundnut genotypes (100%) under study. Conclusions Hence, focusing research on the available knowledge of functionally characterized genes of molecular model crops and vast list of annotated orthologous genes present in ‘Omics’ databases, widens the scope to tag the genes at molecular level and thereby to improve the cropslike groundnutthat has meager progress in gene tagging;by pyramiding of desirable genes with high veracity.

The forty-five genotypes of groundnut were evaluated at Field Experimentation Centre of the Department of Genetics and Plant Breeding, Naini Agricultural Institute, SHUATS, Prayagraj (U.P.) during kharif, seasons of 2021-22 and 2022-23 in four environments condition of Randomized Block Design with three replications. Observations were recorded on 17 yield and its attributing characters. Analysis of variance revealed the presence of significant amount of variability among the groundnut genotypes. The findings of the ANOVA observed a highly significant variation (p ≤ 0.01) for all the traits evaluated. Maximum genotypic coefficient of variation (23.12) and phenotypic coefficient of variation (25.92) was recorded for number of branches per plant. The topmost heritability was recorded for hundred pod weight (98.70%) followed by days to maturity (98.60%) with genetic advance hundred pod weight (41.47%) and days to maturity (24.34%). The traits with least influenced by the environment as well as governed by the additive genes and direct selection for improvement of such traits can be beneficial. Analysis of genetic diversity using Mahalanobis' D2 statistic was carried out in 45 genotypes. These genotypes were grouped into seven clusters. Cluster IV had the maximum number of genotypes. The analysis further indicated that the genotypes of common geographic origin or same location were grouped into different clusters which suggested a lack of relationship between genetic and geographic diversity. Plant height showed relative contribution was the highest 16.67%, then followed by hundred pod weight (14.95%) and pod yield per plant (8.59%).
