“…An increased environmental influence on these traits is indicated by the fact that the phenotypic coefficient of variation was marginally larger than the genotypic coefficient of variance ( Joshi and Patil (2018). Similar findings for days to fifty percent flowering were observed by Erande et al (2014), Deshmukh et al (2019), Mankar et al (2021) and Kolhe et al (2022). Low heritability (9.27%) coupled with low GAM (0.52) was noticed for uniformity index suggesting the environmental influence on the trait and selection is highly ineffective.…”

The purpose of the study was to examine the genetic variability, heritability and genetic advance as a per cent of mean among the six parents selected through principal component analysis and 30 hybrids of desi cotton. The experiment was laid out in during kharif,2022, at the Department of Cotton, TNAU. Five fibre quality traits and 13 yield contributing traits were analysed as a part of genetic variability investigations. With the exception of the uniformity index, ANOVA demonstrated significance for all of the characteristics examined, suggesting that parents and hybrids have adequate amount of variation. An increased environmental influence on these traits is indicated by the fact that the phenotypic coefficient of variation was marginally greater than the genotypic coefficient of variance. Positive and significant correlation with seed cotton yield per plant was observed for plant height, number of sympodia per plant, number of bolls per plant, boll weight and number of seeds per boll which suggested that increase or improvement in these characters lead to improvement in seed cotton yield/ plant. The traits namely, fibre strength, lint index and number of bolls exerted a high direct effect on seed cotton yield while, boll weight and plant height exerted a moderate positive direct effect on seed cotton yield. The hybrids K12 × RG763 and CNA1007 × RG763 can be used for the better attainment of yield as they have highest boll weight along with seed cotton yield per plant and ginning outturn.

“…Considering residual correlations, the environment affected the characters in opposite directions only a few times, as observed in Apodi, 2013, between oil content and the characters one boll weight, uniformity and short fiber index, and in Barbalha, 2014, among oil content and spinning. Some studies with cotton (Dani, 1991;Munawar & Malik, 2013;Erande et al, 2014) report no correlation between oil content and characters related to yield and fiber quality; others, however, show significant correlations (Mert et al, 2005;Qayyum et al, 2010;Badigannavar & Myers, 2015).…”

-The objective of this work was to evaluate the oil content and characters related to fiber quality and yield in cotton lines (Gossypium hirsutum), in order to select genotypes with high oil content and acceptable levels of the other characters. Twenty-two F 6 lines and three checks were cultivated in three field trials -two in the municipality of Apodi, in the state of Rio Grande do Norte, and one in the municipality of Barbalha, in the state of Ceará, both in Brazil. The genetic parameters and the genetic gain from selecting 20% of the lines were estimated according to their means in each environment and in the group of environments. Regarding oil content, there is genetic variability, and the selection based on the overall mean is indicated, since this character showed high heritability, with 4.58% expected gain. The lines selected with this criterion have oil contents between 23.52 and 24.51%, which are higher than those of the Brazilian cultivar BRS Aroeira with the highest grain oil content (22.04%).Index terms: Gossypium hirsutum, gain from selection, genotype x environment interaction, indirect selection, seed quality. Seleção de linhagens de algodão para alto teor de óleoResumo -O objetivo deste trabalho foi avaliar o teor de óleo e os caracteres relacionados à qualidade e ao rendimento de fibra em linhagens de algodão (Gossypium hirsutum), para selecionar materiais com alto teor de óleo e níveis aceitáveis dos demais caracteres. Vinte e duas linhagens F 6 e três testemunhas foram cultivadas em três ensaios de campo -dois em Apodi, RN, e um em Barbalha, CE. Os parâmetros genéticos e o ganho com a seleção de 20% das linhagens foram estimados de acordo com suas médias em cada ambiente e no conjunto de ambientes. Quanto ao teor de óleo, há variabilidade genética, e a seleção com base na média geral é indicada, pois, esse caráter apresentou elevada herdabilidade, com ganho esperado de 4,58%. As linhagens selecionadas por este critério apresentam teores de óleo entre 23,52 e 24,51%, superiores aos da cultivar brasileira BRS Aroeira com maior teor de óleo no grão (22,04%).Termos para indexação: Gossypium hirsutum, ganho de seleção, interação genótipo x ambientes, seleção indireta, qualidade da semente.

Cotton production per hectare is low in Pakistan due to many biotic and abiotic factors. As boll is the basic determinant for yield in cotton crop, a study on within boll yield parameters was carried out using 24 cotton bulk and 2 check varieties to check their variability for within boll yield components. The experiment was performed in the research area of the Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad. The genotypes were seeded in two replications following a randomized complete block design. Data were subjected to analysis of variance to check significance among different genotypes. Genotypes were significantly different. The genotype PB-132 performed best for most parameters including GOT, lint index, lint mass per seed, and seed density. Correlation analysis was applied to find out the association of these parameters. Seed cotton yield was positively associated with the GOT, boll weight and number of seeds per boll while it negatively correlated with fiber fineness, seed volume, and seed surface area. The first principal component showed 26.37%, the second component showed 17.93%, the third component showed 14.88%, and the fourth component showed 14.40% of total variation. PCA analysis showed the genetic diversity among cotton genotypes. The current study's findings revealed the potential of different bulks of cotton for developing high-yielding varieties. This information may be used to develop breeding strategies to enhance cotton production and variety.
