“…According to Milligan et al (1990), a positive correlation between DS and Brix is to be expected because large stalk diameters tend to produce a high concentration of juice. In this study, the traits HS and DS showed moderate additive correlation, and other studies (Liu et al, 2007) have reported similar results. High correlations (>0.90) were obtained for WS with HS, CY, and SY.…”

“…Liu et al (2007) found a significant and high dominance component for WS and also a significant effect of the interaction between dominance and site; however, limited information has been reported in the literature about this component. For HS, DS, and WS, further insight through appropriate experiments is required to determine if the component d 2 (Eq.…”

Estimation of Additive and Nonadditive Genetic Components of Sugarcane Families Using Multitrait Analysis

et al. 2014

Sugarcane (Saccharum spp. interspeci c hybrids) cultivars are a polyploidy and heterozygous complex of genotypes with a large amount of genotypic variability. is study evaluated several commercial traits from a series of trials to provide a better understanding of the genetic structure of this population with the aim of identifying future breeding strategies. Data were analyzed using univariate and bivariate methods on single-and multiple-site linear mixed models. In addition, the top-yielding families using the best linear unbiased prediction were selected and further studied by performing a principal component analysis to facilitate understanding of their morphological characteristics. e traits evaluated were: stalk number, stalk weight, stalk diameter and height, juice percentage of soluble solids (Brix), cane yield, and sugar yield. e results of the single-site analyses showed that stalk height, stalk diameter, and Brix were the most important variables because of the higher potential gains in yield based on their heritability values. In the multiple-site analyses, relevant nonadditive e ects (i.e., dominance) were detected for the variables cane yield, sugar yield, stalk weight, stalk diameter, and stalk height. e selection of the top-yielding families by principal component analysis produced two groups of diverging morphological characteristics or ideotypes. Finally, bivariate analyses showed, among others, a high additive genetic correlation between stalk number and stalk weight.

“…Future varieties bred specifically for secondgeneration biofuels will be dissociated from highsucrose yields, but instead will aim at total biomass production per area.Some traits are additive while others present dominant effects. Additive effects can be useful for breeding in early generations of the program while dominant effects are more useful in hybrids (Liu et al, 2007). Increase of sugar yield has always been a major goal of breeding programs.…”

This work was carried out at Subbhia experimental station for sugar crops. The present investigation aims at inducing polyploidy in sugar cane (Saccharum officinarum) and to investigate its agronomic traits. Colchicine was used to produce poly ploidy from three cultivars. These cultivars are (C9 G.T. 54-9, PH 8013 and NCO 310). Buds were treated with 0.05% colchicine solution. Treated segments were allowed to germinate until a shoot system length of 40 cm had reached. Plants were then transferred and allowed to grow in the yield. The growing plants were examined for polyploidy firstly by Guard cells of Stomata, Chloroplasts, DNA content in leaves, and chromosomes from adventitious roots initiated at the laboratory. Physico-chemical properties for chromatins and deproteinized DNA were estimated. Total soluble solids (T.S.S); plant height and plant diameter were estimated. The obtained results would be summarized as follows: The present studies aimed to produce polyploidy in cultivar C9. The obtained results showed that the average of polyploidy was found to be 9% for C9 and 4% for PH 8013. Regarding chemical composition and melting temperatures of chromatins different ratios were obtained reflecting differential transcriptional activities. However, active and repressed fractions of chromatin were estimated. With respect to the evaluated agronomic characteristics different values were observed.
