“…Hence, selection for these characters will help in selecting genotypes with high seed cotton yield per plant. Similar results for positive correlation between yield and its components traits were already reported by Basbag and Gencer (2007), Aguado et al (2008), Do-Thi-Haan et al (2008), Kalpande et al (2008) and Reddy and Reddy (2008).…”

Diploid cotton Gossypium herbaceum has wide adaptability under rainfed situation and also high degree of resistance to biotic and abiotic stresses. Correlation and path coefficient analysis have been worked out using five phenotypically diverse genotypes of diploid cotton (G. herbaceum (3) and G. arboreum (2)), with the objective to study the association between seed cotton yield and its components for seven quantitative characters in 202 progenies of desi cotton. High significant positive phenotypic and genotypic correlation coefficients were noticed for some of the important traits like number of bolls per plant, boll weight and plant height traits towards seed cotton yield. And also among the traits (inter) significant association was noticed which indirectly contributed to seed cotton yield. The correlation and path coefficient analysis together indicated that these traits should be considered as selection indices for seed cotton yield plant improvement programme.

“…Selections in such promising hybrids can be used in hybrid cotton production for increased seed cotton yield. Tang et al (1996), Basal and Turgut (2005), Iqbal et al (2005), Khan et al (2005), Esmail (2007 and Aguado et al (2008) also mentioned that dominant gene effects were higher than additive for yield, because additive variance was found smaller than dominant components and that expression was also confirmed by degree of dominance. However, Luckett et al (1989), Ahmad et al (2003a,b), Aguiar et al (2007) and Gamal et al (2009) mentioned that for seed cotton yield, the additive gene effects were more important under favorable conditions but under stress, the nonadditive effects of the genes were more imperative.…”

“…Hussain et al (1999), Khan (2003) and Khan et al (2007) analyzed the genetic mechanism in diallel cross of G. hirsutum and found that the HaymanJinks additive-dominance model was adequate for most of the traits in both generations. Aguado et al (2008) also mentioned that the differences between Wr and Vr indicated that the additive/dominance model was adequate for seed cotton yield and its components. Lack of significant variations in the Wr -Vr arrays for seed cotton yield, lint% and lint yield suggested that assumptions of diallel analysis were valid (Godoy and Palomo, 1999).…”

“…Consequently, the use of genotypes with desirable genetic components of variance is a prerequisite for synthesis of physiologically efficient and genetically superior genotypes showing promise for increased production per unit area under a given set of environments (Khan et al, 2009a). To achieve these objectives using quantitative genetics, workers have advocated a comprehensive study of assumptions of additive-dominance model (through different scaling tests), genetic mechanism and genetic components of variation which control the various plant characters in parents and their cross combinations under various environmental conditions (Hayman, 1954;Mather and Jinks, 1982;Tang et al, 1993Tang et al, , 1996McCarty et al, 1996McCarty et al, , 2004aHussain et al, 1999;Khan, 2003;Ragsdale, 2003;Lukonge, 2005;Mei et al, 2006;Wu et al, 2006;Esmail, 2007;Lukonge et al, 2007;Khan et al, 2007Khan et al, , 2009aAguado et al, 2008;Ali et al, 2008;Ali and Awan, 2009;Basal et al, 2009;Gamal et al, 2009).…”

The nature and magnitude of genetic effects on morpho-yield traits were studied in a 6 × 6 F 1 and F 2 diallel cross in upland cotton. An additive-dominance model was adequate for most of the traits except plant height and seed cotton yield, where the model was partially adequate. Genetic parameters were estimated following Hayman's and Mather's model. Additive effects controlled lint percentage and monopodia in both generations, and plant height and sympodia in F 2 . Non-additive inheritance with over-dominance controlled yield in both generations, and plant height and sympodia in F 1 . Most traits presented an unequal proportion of positive (U) and negative (V) alleles in the loci (H 2 < H 1 ) and an asymmetrical distribution of genes in the parents (H 2 /4H 1 < 0.25 and F different to zero). The value of H 2 /4H 1 was lower than maximum value (0.25) for all of traits, which arises when U = V = 0.5 over all loci. The proportion ͌ʳʲ 4DH1 ʲʲ + F ʲ/͌ʳʲ 4DH1 ʲʲ -F ʲ) confirmed by half of the traits that dominant alleles were in excess as compared to recessive alleles. Dominance effects (h 2 ) for most of the traits suggested that substantial contribution of dominance was not due to heterogeneity of loci in these parameters. Broad and narrow sense heritabilities were high for most of the traits. Correlation coefficient between the Wr + Vr and mid parental (y) indicated that dominant genes were responsible for increased sympodia, lint % and yield, and recessive genes increased monopodia and plant height. Genetic gain was encouraging for most traits. Cultivar CIM-1100 was identified by genetic advancement as a promising parental cultivar to cross combinations.Additional key words: additive-dominance model; additive and dominance effects; D, H 1 & H 2 genetic components of variance; seed cotton yield; upland cotton. ResumenEfectos genéticos en caracteres morfológicos y de rendimiento en algodón (Gossypium hirsutum L.)Se estudió la naturaleza y la magnitud de los efectos genéticos sobre los caracteres morfo-productivos en un cruce dialélico F 1 y F 2 de 6 × 6 en algodón tipo upland. Para la mayoría de los caracteres, excepto altura de planta y rendimiento de semilla, fue adecuado un modelo aditivo-dominante. Se estimaron los parámetros genéticos según Hayman y Mather. Los efectos aditivos controlaron el porcentaje de pelusa y los monopodios en ambas generaciones, y la altura de la planta y los simpodios en la F 2 . La herencia no aditiva con superdominancia controló el rendimiento en ambas generaciones y la altura de planta y los simpodios en la F 1 . La mayoría de los caracteres presentaron una proporción desigual de alelos positivos (U) y negativos (V) en los loci (H 2 < H 1 ) y una distribución asimétrica de los genes en los parentales (H 2 /4H 1 < 0,25 y F 0). El valor de H 2 /4H 1 estuvo por debajo del valor máximo (0,25) para todos los caracteres, lo que surge cuando U = V = 0,5 en todos los loci.

Verticillium wilt causes massive annual losses of cotton yield, but the mechanism of cotton resistance to Verticillium dahliae is complex and poorly understood. In this study, a comparative proteomic analysis was performed in resistant cotton (Gossypium barbadense cv7124) on infection with V. dahliae. A total of 188 differentially expressed proteins were identified by mass spectrometry (MALDI-TOF/TOF) analysis and could be classified into 17 biological processes based on Gene Ontology annotation. Most of these proteins were implicated in stimulus response, cellular processes and metabolic processes. Based on the proteomic analysis, several genes involved in secondary metabolism, reactive oxygen burst and phytohormone signaling pathways were identified for further physiological and molecular analysis. The roles of the corresponding genes were further characterized by employing virus-induced gene silencing (VIGS). Based on the results, we suggest that the production of gossypol is sufficient to affect the cotton resistance to V. dahliae. Silencing of GbCAD1, a key enzyme involving in gossypol biosynthesis, compromised cotton resistance to V. dahliae. Reactive oxygen species and salicylic acid signaling may be also implicated as regulators in cotton responsive to V. dahliae according to the analysis of GbSSI2, an important regulator in the crosstalk between salicylic acid and jasmonic acid signal pathways. Moreover, brassinosteroids and jasmonic acid signaling may play essential roles in the cotton disease resistance to V. dahliae. The brassinosteroids signaling was activated in cotton on inoculation with V. dahliae and the disease resistance of cotton was enhanced after exogenous application of brassinolide. Meanwhile, jasmonic acid signaling was also activated in cotton after inoculation with V. dahliae and brassinolide application. These data provide highlights in the molecular basis of cotton resistance to V. dahliae. Molecular & Cellular
