“…For secondary peel color, secondary pulp color, color distribution, haulm diameter, haulm length, type of leaf, mature leaf color and petiole length, we verified an expression ranging from 70 to 83%, of possible classes within each descriptor (Figure 1). Vargas et al (2018), evaluating 172 morpho-agronomic classes, distributed in 23 morpho-agronomic descriptors, verified 70.35% of expression of these classes, values which were below those found in this study. Andrade et al (2017), studying 60 accessions and 24 descriptors of shoots and roots, verified wide variability among the accessions.…”

“…The authors observed groupings of 30 genotypes in group 1 and 24 in group 2. Vargas et al (2018), studying 96 accessions of sweet potato, verified 11 groups formed, being the first group with 70 accessions, showing existence of great genetic variability. In group 3, we can verify 7 grouped genotypes.…”

“…Despite the difficulties in classifying morpho-agronomic traits according to subjectivity, which was verified by Vargas et al (2018), this methodology for investigating germplasm diversity is often carried out (Fongod et al, 2012), since this is a low-cost technique as well as easy to be applied (Vieira et al, 2008).…”

Sweet potato is a vegetable of great importance in human consumption, due to its high nutritional value. It presents high phenotypic variation, with different forms of roots, leaves and vines. Given the above, we aimed to study the genetic divergence of sweet potato genotypes based on morpho-agronomic traits. The experiment was conducted in an experimental area of Unesp, Ilha Solteira Campus, located in Selvíria-MS. The experimental design used was randomized blocks with two replicates, including 200 genotypes and ‘Beauregard’ as a biofortified control. Shoot morphological traits of the genotypes were evaluated at 110 days and root morphological traits were evaluated at 127 days after planting. We used the obtained data to perform descriptive analysis, in percentage of phenotypic classes. In order to study genetic divergence, multivariate analysis was performed, grouping was done using Tocher’s and Ward’s methods. We also analyzed relative contribution of each trait for genetic divergence. Statistical analyzes were performed using Genes software and SAS. Wide genetic variability could be verified in the population studied in this experiment, being possible to obtain genetic gains in recombination between genotypes. Grouping using Tocher’s method was more effective for discriminating dissimilarity between genotypes. The low relative importance of leaf size, internode diameter and secondary peel color makes further evaluation of these traits unnecessary, reducing labor costs, cost and execution time.

Estimating genetic parameters is an essential procedure to define strategies for breeding and selection of higher yielding genotypes. The use of a selection index can assist in decision making by combining the high yield trait with other desirable traits. The objective of this study was to verify the possibility of gains from selection in a sweet potato population to select potentially promising genotypes. The experiment was conducted in a randomized block design, with three plants per plot and two replications, consisting of 255 sweet potato genotypes and a commercial cultivar (256 treatments). The data were analyzed through REML/BLUP. Genetic gains were evaluated using selection indexes based on the rank sun. The plant population tested showed high genetic variability; 81.25% of the traits had genotypic coefficients of variation above 20%, which indicates conditions favorable to selection with considerable genetic advances. CERAT31-01, CERAT21-02, and CERAT51-30 can be recommended as the most promising genotypes.

“…Porém, o cultivo de batata-doce no Brasil e sua utilização, principalmente para os fins supracitados, são mal aproveitados. A produtividade nacional é da ordem de 12 t ha -1 e em função da rusticidade dos materiais, as plantas são cultivadas em áreas marginais, muitas vezes sem adubação complementar ou técnicas de plantio (ANDRADE JÚNIOR et al, 2009;VARGAS et al, 2017). Adicionalmente, existe grande número de acessos cultivados, que apresenta grande variabilidade genética e fenotípica (ANDRADE JÚNIOR et al, 2014), fatores que dificultam as recomendações para cultivo.…”

Existem vários fatores que afetam a fotossíntese, como o déficit físico, o estresse térmico, a concentração de gás interno e externo e a intensidade da luz, no entanto, também pode variar com o material genético ou cultivar avaliado. O objetivo deste estudo foi avaliar as características fisiológicas de setenta e sete genótipos de batata-doce e agrupá-los de acordo com sua produção de matéria fisiológica e seca. Para este fim, foi estabelecido um delineamento de blocos ao acaso (DBC). As características fisiológicas foram coletadas 60 dias após o transplante das mudas de batata-doce nas folhas mais expandidas contadas a partir do meristema apical do ramo mais longo. Foi utilizado um analisador de gás não-infravermelho (IRGA). Com o uso deste dispositivo foi avaliado: a concentração de CO2 (Ci) e a taxa fotossintética (A), a condutância estomática dos vapores de água (Gs), a taxa de transpiração (E), a eficiência do uso da água (EUA) e a proporção Ci / carbono atmosférico (Ci / Ca). Aos 150 dias após o transplante, determinou-se a massa de matéria seca total das plantas (MST). Os genótipos de batata-doce avaliados apresentaram comportamento diferente em relação às diferentes características fisiológicas estudadas. Valores mais elevados de A, Gs, Ci, Ci / Ca e E foram observados em UFVJM-57, mas UFVJM-06 mostrou os valores mais baixos em relação a essas características.
