In this way, the objective of this work was to study, via mixed models, the performance of advanced selections of peach trees with low chilling requirements. Sixteen advanced peach selections from the EPAGRI Drupaceae breeding program were evaluated during three crops (2017, 2018, and 2019) and at two sites with different altitudes (220 m and 360 m). The characters evaluated were: yield (t.ha</span><span class="fontstyle0">-1</span><span class="fontstyle0">), maturation cycle (days), average fruit mass (g), soluble solids (°BRIX), and titratable acidity (%). They were analyzed via mixed models that use variance estimates obtained by the REML method (restricted maximum likelihood) by the SELEGEN – REML/BLUP program. Several genotypes showed good performance for the assessed characteristics, where sel. 0574 stood out as it obtained a good yield, high sugar content, and a good sugar/acidity ratio. Selections 0184, 0574, 0374, and 0791 present better performances for fruit yield, such as stability and adaptability (HMGV, RPGN, and HMRPGN). For the traits yield and average fruit mass, the effects of the environment do not change the behavior of the selections, making the genotypes representative of the region of interest.</span> </p> Marina Martinello Back, Emílio Della Bruna, Alexsander Luís Moreto, Henrique Belmonte Petry, Gilmar Bettio Marodin ##submission.copyrightStatement## Tue, 25 Apr 2023 00:00:00 +0000 BRS FS313: JALO TYPE COMMON BEAN CULTIVAR WITH LARGE BEANS AND HIGH YIELD <p><span class="fontstyle0">BRS FS313 is a common bean cultivar with high yield (3,200 kg.ha</span><span class="fontstyle0">-1</span><span class="fontstyle0">), jalo type bean grain, and greater 100-seed weight (50 g).

The Soybean x Sugarcane (SSC) production system operates with high efficiency and contributes to the sustainability of agribusiness. Soybean cultivars suitable for use in SSC must have an early cycle, adaptation to the edaphoclimatic region, and high yield. The Value of Cultivation and Use (VCU) assays are conducted in different edaphoclimatic regions, to identify promising soybean genotypes in an advanced stage of inbreeding. The objective of this work was to identify soybean genotypes with high adaptability and stability that are possible candidates for registration and protection of new commercial cultivars, for use in the SSC system in the São Paulo State, Brazil. Twenty genotypes and four commercial cultivars were evaluated in six environments, in a randomized block design with three replications. To verify adaptability and stability, the AMMI method was used.

There are several factors, with and without the control of plant breeders, that affect the success obtained with the IRS. For it to be more efficient, such factors must be judiciously assessed. In this light, this study aimed to compare a large number of variables involved in the efficiency of the IRS. Selection gain (SG) estimates with the IRS were obtained. Considering different variables under the control of the breeders such as the following: two types of progenies, half-sib (HS) and full-sib (FS); three experiment evaluation conduction strategies with multiple tree plots (MTP), single tree plots (STP), and clonal progeny test (CPT), and other variables. Variables without the control of plant breeders were also considered: mean allele frequencies of the populations (p); level of dominance (d/a); broad-sense heritability at the individual level (</span><span class="fontstyle2">h²</span><span class="fontstyle0">). Over 3000 SG estimates were obtained. When the CPT was used, the SG was always higher than that obtained with STP or MTP; the SG when employing HS was always higher than with FS. However, the employment of HS, especially when using clones for the recombination, has the serious restriction of not allowing higher selection intensities and maintaining the same number of progenies in the different IRS calculations. In this context, the employment of FS is more advisable since it allows applying a more significant selection intensity and enables more homogeneous recombination.</span></p> Magno Antonio Patto Ramalho, Thaise da Silva Souza, Vitor Passos da Silva Junior ##submission.copyrightStatement## Tue, 25 Apr 2023 00:00:00 +0000 ADAPTABILITY AND PHENOTYPIC STABILITY OF UPLAND RICE GENOTYPES IN MOZAMBIQUE <p><span class="fontstyle0">The alternative adopted in rice (</span><span class="fontstyle2">Oryza sativa </span><span class="fontstyle0">L.) breeding programs to decrease the effect of genotype x environment to reduce the effect of the interaction of genotype x environment (G x E), consists in the evaluation of genotypes in different environments and years, for an accurate recommendation of the most stable and adapted genotypes.

As such, the goals of this study were to evaluate genetic diversity by means of agronomic and molecular traits and to investigate the genetic structure of a population of sour passion fruit, making it possible to select superior and contrasting genotypes. A total of 95 genotypes belonging to 20 half-sib families of sour passion fruit were selected. For molecular traits, 170 microsatellite (SSR) primers and 58 Inter Simple Sequence Reapeats (ISSR) primers were used. On the basis of this information, estimates of genetic diversity parameters, genetic distances, and grouping of genotypes were determined. Lastly,a joint analysis was performed with the groupings of agronomic and molecular information.<br>A differentiated structuring between phenotypic and molecular groupings was found. It was noticed the formation of five groups for phenotypic traits and three others for SSR and ISSR. The heterozygosity verified was greater than the expected, suggesting a significant number of heterozygous individuals. With respect to the joint analysis, it was verified an entanglement of 0.57 and 0.58, pointing out the divergence in the distribution of genotypes among the dendrograms. There was a greater genetic variability via phenotypic rather than molecular traits.

As follows, the objective of this study was to estimate the genetic parameters for agronomic and nutritive traits of forage peanut to subsidize the selection of more adapted genotypes. We evaluated 67 genotypes in three separate trials with two common controls. Agronomic and nutritive data were analyzed using the mixed model methodology (REML/BLUP) for each trial. Genetic parameters were estimated for all the variables and genotypic values served as a basis for checking the genetic correlation among traits. There was genetic variability and environmental influence for the traits analyzed, except for nutritive ones. Individual heritabilities, in general, were low to moderate and the traits of forage production (vigor, height, ground cover, and total and leaves dry matter yields) correlated with each other in the three trials. There is a favorable condition for the selection of agronomic traits, with high accuracy and consistency among trials.

Drought is one of the main abiotic stresses worldwide and affects about 60% of the bean growing area. Advances in molecular marker technologies offer powerful methods to examine elationships between traits, generating a large volume of potentially useful information to help breeding programs. This study aimed to use the DArT (Diversity Arrays Technology) platform for common bean together with microsatellites (SSRs) and SNPs (Single Nucleotide Polymorphism) for mapping the AND 277 x SEA 5 population from CIAT (Colombia), and locating QTLs associated with drought tolerance. A total of 4,468 DArTs, 288 SNPs and 180 SSRs were used in genotyping. Phenotyping of the 105 inbred recombinant lines (RILs, F8 generation) was performed by evaluating 18 traits associated with drought tolerance using a completely randomized design with four replications, applying a terminal stress in the vegetative phase V3/V4. Five SSRs, 91 SNPs and 4,468 DARTs were used for QTL detection which was performed through Statistical Machine Learning (SML). Eighteen QTLs were identified for the non-irrigated treatment for vase experiment and 05 QTLs for rhizotron experiment. All QTLs detected under drought conditions had the SEA 5 parent allele. This study is important for genetic improvement not only for a better understanding of the genetic inheritance of such a complex trait as drought tolerance, as well as for finding molecular tools to be used for marker-assisted selection.</p> Boris Briñez, Alisson Fernando Chiorato, Sérgio Augusto Morais Carbonell, Luciana Lasry Benchimol-Reis ##submission.copyrightStatement## Sun, 10 Dec 2023 00:00:00 +0000 AGRONOMIC PERFORMANCE OF LOCAL DRYLAND RICE VARIETIES OF THE FAR WEST OF SANTA CATARINA, BRAZIL <p>Dryland rice varieties are conserved in situ on farm in the far west of the state of Santa Catarina, southern Brazil. The objective of this work was to evaluate the agronomic performance of 34 local dryland rice varieties from this region, which they represent four morphological groups. The experiments were carried out in two municipalities in Santa Catarina (Anchieta and Florianópolis), in complete randomized blocks design with four replications. The differences were significant (p ≤ 0.05) for the effects of genotype, environment, and genotype x environment interaction, for the stem length variable. All other variables showed significant differences for the effects of genotype and interaction and not significant for the environment. Yield, stem length, number of tillers per plant, number of branches and grains per panicle ranged from 1,458.59 to 4,193.80 kg ha-1, 69.2 to 113.1 cm, 2.5 to 4.0 tillers per plant, 8.5 to 10.2 branches and 75.9 to 97 grains, respectively. The highest yield values and stem length were obtained in Florianópolis. Resistance to lodging was greater in Anchieta, local of origin of the varieties. Yield, stem length and the number of grains showed dependence by the chisquare test (p ≤ 0.05), in relation to the conservation time of the varieties by the farmers.
