“…In studies with sugarcane families, Jackson et al (1995) and Moraes et al (2010) found similar values for these traits. In studies of energy cane families, Silveira et al (2016) found very similar values of CVe for the traits PC, FIB, TCH, TSH, and TFH to those obtained in this study. The high value of CVe for TCH, according to the classification proposed by Gomes (1990), can be attributed in part to the data heterogeneity and the strong environmental influence on this complex trait.…”

“…These results are consistent with the study of Kang et al (1983) for BRIX and TCH; of Melo et al (2006), for PC, BRIX, FIB, and TCH; and in the stufy of Silva et al (2011), for the traits BRIX, PC, TCH, and TSH. Silveira et al (2016) found very close heritability values for PC, FIB, and TCH, and lower values for TSH and TFH in evaluations of sugarcane families.…”

“…With the feasibility of using straw and the prospect of using the entire cane biomass in the production of cellulosic ethanol and other products, new lines of sugarcane research have arisen in Brazil and other countries, mainly focused on increasing the fiber content and biomass production of future cultivars (Matsuoka et al, 2014;Silveira et al, 2016).…”

ABSTRACT. The forecast of a growing energy demand in the coming years has aroused particular interest in biomass for energy cogeneration, to diversify the energy matrix by using clean and renewable sources. To meet the new demands of the sugarcane industry, this study evaluated the agronomic performance and estimated genetic parameters for yield traits in sugar-and energy cane families derived from planned crosses. The cane families were assessed in the northwest of the State of Paraná, county of Paranavaí, in a randomized complete block design, with three replications. The evaluations were carried out 12 months after the first cut, in the ratoon cane cycle, in December 2014, under very unfavorable conditions for the crop, due to the low fertility and waterholding capacity of the soil. Besides, the crop was evaluated at the end of the harvest, when the agricultural and industrial quality of the crop is reduced. The following traits were evaluated at the plot level: soluble solids content, apparent sucrose content (PC), fiber content, tons of cane per hectare, tons of sucrose per hectare (TSH), and tons of fiber per hectare (TFH). High genetic variability was observed for all evaluated traits, with accuracy estimates from 0.69 (TSH) to 0.92 (PC), and high heritability (up to 0.84), indicating the possibility of genetic progress. The sugarcane families derived from crosses of Saccharum spontaneum and Saccharum robustum species with sugarcane hybrids had the highest fiber contents. Highest sugar contents were found in sugarcane families resulting from crosses of sugarcane clones and conventional cultivars. The TSH means were highest in the families F160 x MEX68-200 and RB855156 x RB987935. The highest genotypic mean for TFH was observed in the special polycross involving cultivar RB036066 with S. spontaneum accessions as pollen donors.

“…There are continuous cylinders of sclerenchyma close to the periphery. S. spontaneum contained high fiber content, where this is in harmony with other species (Silveira et al, 2016). Ground Tissue is parenchymatous without the demarcation cortex and pith.…”

The anatomical structure of plants is largely varied according to genetics as well as the environmental conditions. The present study aims to describe the anatomical features of three species of family Poaceae growing naturally in canal bank habitat namely: Arundo donax, Pennisetum setaceum and Saccharum spontaneum. These plants are referred as medicinal, grazing or fiber producing plants. Samples were obtained from the canal banks in Nile delta of Egypt. The samples were fixed in formalin-acetoalcohol and cross sections were prepared, examined using full automatic Olympus microscope and photographed at different power. In the present study, regarding leaves, the general appearance of the leaves sections showed either flat or V-shaped blade. The leaf blades of the three plants show a typical monocot organization. The mesophyll cells showed no distinct differentiation into palisade or spongy tissue. In P. setaceum and S. spontaneum, the leaves have distinct bulliform cells which enable the leaf to fold or roll. The vascular bundles of leaves are collateral, closed, numerous and diffuse in distribution. The vascular bundles are larger in size and surrounded by a sheath of fibers. However, the cross-section of the stem is more or less circular. Ground tissue is parenchymatous and not differentiated into cortex and pith in P. setaceum and S. spontaneum, while A. donax has large hollow pith. The bundles are collateral and are usually surrounded by a sclerenchymatous sheath.

“…The significance of the variances of progenies (genetic) at the 1% probability level by the F test, for the four experiments, indicates the existence of genetic variability between the progenies of each type of pollination and allows for genetic gains through selection (Silveira et al, 2016). This significant effect, in particular the progenies from self-pollination, in which of the four experiments obtained greater percentage gains in three of them, may be related to the higher level of homozygosis, expressing with it greater divergence between the progenies, the one that allows the percentage of larger genetic gains (Vargas-Reeve et al, 2013).…”

Productive potential and castor bean selection of the FCA-PB cultivar progenies

et al. 2020

Castor bean is a very important crop, however, in Brazil it still has relatively low productivity, 0.47 Mg ha-1 as a mean. Besides that the Country has significant castor oil demand and depends on international commerce to complement its production. The solution of these problems goes through the development of genotypes highly productive and adapted to the producing regions. So, the objective of this research was to evaluate the productive potential and selection of castor progenies of the cultivar FCA-PB, resulting from three types of pollination, in two crops and in two localities of the State of São Paulo. Grain productivity was evaluated, and some genetic parameters were estimated. In relation to the 2005/2006 crop, the progeny 49 cultivated in the locality of São Manuel produced 4170.66 kg ha-1 of grains. The highest heritability coefficients were observed in the 2005/2006 crop in the locacity of Araçatuba.
