Genetic advance over per cent mean

For present study experimental material consisted of 25 elite genotypes of ajwain. Observation was recorded on 11 quantitative traits in ajwain. High estimates of heritability (broad sense) were obtained for oil content and seeds per umbelet. The magnitude of PCV as expected was greater than the corresponding GCV for all the characters indicating importance of environment in expression of characters.

The present experiment aimed to evaluate variability, heritability and genetic advance as per cent over mean for physiological and biochemical traits in twenty one thermo tolerant tomato genotypes. The experiment was conducted at the Experimental Farm, Division of Vegetable Science, Indian Agricultural Research Institute, New Delhi during spring– summer season (March-June) of the year 2014.

In order compute genetic variability, heritability and genetic advance expressed as per cent of mean, an investigation was carried out with 79 plants of F2 population of MFC-09-12 × PGCP-12 and 90 plants of F2population of MFC-08-14 × PL-3 in cowpea. Considerably high amount of variability was observed for the thirteen quantitative and qualitative characters under study.

Genetic variability, heritability, genetic advance and correlation were estimated for charcoal rot component traits, yield and its component traits. High values of PCV and GCV were observed for majority of traits, indicating a greater scope for improvement of these traits. High heritability coupled with high genetic advance over mean was observed for majority of traits, indicating these characters would be more effective for further improvement through simple selection.

An experiment was conducted to estimate genetic variability, heritability and genetic advance expressed as per cent of mean in F2 population of two crosses viz., DCS-47-1 × PL-1 and DCS-47-1 × PGCP-12 in cowpea. Analysis of variance revealed significant differences among the segregants tested for all the sixteen characters. High PCV and GVC were observed for number of secondary branches per plant, leaf to stem ratio, number of pods per plant, green fodder yield per plant, green fodder yield per metre row length and stover yield per plant in both the populations.

Cotton, Recombinant inbred lines (RIL), phenotypic (PCV) and There is a limited genetic variability available in genetic resources of upland cotton (Gossypium hirsutum L.), which restricted the breeding activity. The objective of present study was evaluating the genetic variability in RIL population derived through intraspecific hybridization between RHAP 12 and RHAP 15 genotypes. The 222 RIL were evaluated during kharif 2018 at University of Agricultural Sciences Dharwad.

The present study was conducted to evaluate genetic variability in F2 population of cross Arka Archana × AAC-1 in China aster at the College of Horticulture, Mudigere during 2017-18. The phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the traits. High (>20 %) phenotypic coefficient of variation (PCV) and genotypic coefficient of variation(GCV) was recorded for number of branches per plant, plant spread East-West, number of flowers per plant, disc diameter, individual flower weight and flower yield per plant.

Genetic variability, heritability, genetic advance and genetic advance as a per cent over mean for twenty characters were assessed by field evaluation (part of survey) of two thirty one tamarind genotypes in six districts (viz, Belagavi, Dharwad, Gadag, Bellary, Chitradurga and Gulbarga) with different location during 2018. High degree of variation was observed for all characters. In all cases, phenotypic variances were higher than the genotypic variance.
