“…Analysis of variance showed a significant difference (p <0.01) for all variables, indicating the existence of genetic variability, as also observed by Daronch et al (2019), Pinheiro et al (2013), Monteiro et al (2016;, Medeiros et al (2004), Meotti et al (2012), Nogueira et al (2012) and Oliveira (2018). Gaviraghi et al (2018) add that soybean cultivars, when subjected to different environmental conditions, may show different responses due to physiological alterations emerging mainly from changes in temperature and relative humidity between sites.…”

“…was facilitated by a species originati ng from a temperate climate (GAVIRAGHI et al, 2018). Developing new genotypes adapted to diff erent edaphoclimati c conditi ons is undoubtedly one of the technologies that most contribute to increasing nati onal producti vity, being relevant from an economic and environmental standpoint (DARONCH et al, 2019). In unfavorable environments, soybean genotypes effi cient in taking advantage of the environmental sti mulus show bett er producti ve performance.…”

“…Szareski et al (2015) evaluated the agronomic performance of soybean genotypes and their linear morphological and bromatological relations, seeking gains via breeding. Daronch et al (2019) evaluated the environmental efficiency and genetic divergence of seventeen soybean genotypes, grown during sowing season. Nogueira et al (2012) observed that the connection between traits of the total number of pods per plant and the number of nodes on the main stem can be used to indirectly select soybean grain yield, and Gaviraghi et al (2018) analyzed the adaptation of soybean cultivars in the Upper Middle Uruguay region of the state of Rio Grande do Sul.…”

In recent years, questionings on the behavior of genotypes in different environments are frequent, especially those seeking to disclose the commercial and nutritional value of soybean genotypes. Consequently, this study – which is linked to the IRC Soybean Breeding Program located in Campos Borges, Rio Grande do Sul, Brazil – sought to analyze the physiological and nutritional aspects of S5 Soybean Segregating Families. Research design consisted of complete randomized blocks containing 40 soybean genotypes arranged in four repetitions, corresponding to F5 generation genotypes tested in 2018/2019. This generation was obtained via artificial hybridizations of F1s plants carried out in 2014/2015, F2s in 2015/2016, F3 segregating families in 2016/2017 and F4 in 2017/2018. Traits were evaluated by a statistical model, verifying normality and homogeneity of variances. Behavioral explanation of the F5 Soybean Segregating Families was calculated using analysis of variance, grouping of means, and linear and canonical correlation. Analysis of variance showed a significant difference (p <0.01) for all variables, indicating the existence of genetic variability. F5 Segregating Families IRC8_130 and IRC31_102 show promising results in breeding programs involving physiological and nutritional aspects. Crude protein, crude fiber, first pod insertion height, plant height and number of pods with 4 grains, are dominant and determining characteristics for establishing segregating generations, and can be used in breeding programs.

“…Although the country is one of the world's leading producers of this crop, according to FAO (2016), this year the Brazil imported 3621 tons to meet the industry demand this oil. Thus, there is a demand for the production of castor oil, which can be achieved with the development of highly productive genotypes besides being adapted to the edaphoclimatic conditions of each producing region (Daronch et al, 2019).…”

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.

“…Valores desta magnitude indicam que o emprego de métodos simples de seleção, como massal, proporcionam ganhos expressivos durante o processo de seleção (CRUZ et al, 2014). Segundo Daronch et al (2019), NDF e NDM são importantes características que devem ser observadas na escolha do cultivar, sendo a precocidade uma característica desejável quando se objetiva a semeadura antecipada para realizar a sucessão de culturas e reduzir a pressão de seleção, por permanecerem menos tempo no campo.…”
