Genetic variability, correlation and path analysis of upland cotton (Gossypium hirsutum L.) germplasm for seed cotton yield

open access: yesElectronic Journal of Plant Breeding, 2022
One hundred upland cotton germplasm accessions were evaluated for eight traits to evaluate the per se performance, genetic variability, heritability, genetic advance as a per cent of mean, correlation and path analysis.

Genotypic Variation in Seedling Tolerance to Aluminum Toxicity in Historical Maize Inbred Lines of Zambia

open access: yesAgronomy, 2015
Maize (Zea mays L) is the most important food grain in sub-Saharan Africa and is mostly grown by small-scale farmers under rainfed conditions. Aluminum toxicity caused by low pH is one of the abiotic factors limiting maize production among smallholder ...

ASSESSMENT OF VARIABILITY, HERITABILITY AND CORRELATION IN RICE (ORYZA SATIVA L.) GENOTYPES [PDF]

open access: yesNatural Resources and Sustainable Development, 2021
The amount and pattern of genetic divergence are important factors in selecting desirable genotypes for use in breeding programmes. This research was conducted in Kabre, Dolakha, Nepal in 2020.

The Relationship between Structurally Different Pyrrolizidine Alkaloids and Western Flower Thrips Resistance in F2 Hybrids of Jacobaea vulgaros and Jacobaea aquatica [PDF]

open access: yes, 2011
Segregating plant hybrids often have more ecological and molecular variability compared to parental species, and are therefore useful for studying relationships between different traits, and the adaptive significance of trait variation.

Morphological parameters in breeding for higher seed yield in Indian mustard [Brassica juncea (L.) Czern. & Coss.]

open access: yesElectronic Journal of Plant Breeding, 2019
Highest genotypic coefficient of variation was recorded for number of secondary branches per plant. High genetic variation was found in length of siliqua, seed yield per plant, number of siliqua per plant and 1000 seed weight (g).

Genetic variability of three cassava traits across three locations in Ghana [PDF]

open access: yes, 2016
A study was conducted to assess the extent of genetic variability, broad-sense heritability and correlations for fresh root weight, root number and top weight of five cassava genotypes across three locations in 2 years.

Morphological characterization of maize (Zea mays L.) hybrids under excessive soil moisture stress

open access: yesEnvironment Conservation Journal, 2022
A critical assessment of 32 maize hybrids with two replications for excessive soil moisture stress (ESM) was carried out during Kharif 2019-20. The plants were exposed to waterlogging stress for 12 days at the flowering stage by maintaining a water ...

The causal meaning of Fisher's average effect [PDF]

open access: yes, 2013
In order to formulate the Fundamental Theorem of Natural Selection, Fisher defined the average excess and average effect of a gene substitution. Finding these notions to be somewhat opaque, some authors have recommended reformulating Fisher's ideas in ...

Variability studies in Okra (Abelmoschus esculentus L. Moench)

open access: yesElectronic Journal of Plant Breeding, 2016
Sixty genotypes of okra were evaluated in one location for two years at Chatha, Jammu during 2009-10 and 2010-11. The objective was to study the genetic variability between various economically important traits for the purpose of genetic improvement. The
