ABSTRACT Repeatability allows an estimation of the number of evaluations needed to optimize the selection of superior genotypes, with consequent effects on the research costs in terms of financial and human resources. The objective of this study was to estimate the coefficient of repeatability of biometric and yield traits, related to fruits and seeds of sacha inchi (Plukenetia volubilis), and to define the number of evaluations required for an efficient selection and evaluation of genotypes of the species. A total of 37 non-domesticated accessions were evaluated for 19 months in a randomized block design with 5 replications and 2 plants per plot. The total number of fruits, total number of seeds, total fruit weight, mean fruit weight, and number of seeds per fruit of the accessions were evaluated by monthly sampling. Additionally, seed biometry was assessed in a sample of 30 seeds per accession. Repeatability coefficients were estimated by analysis of variance, principal components and structural analysis. The principal component method based on the covariance matrix was the most appropriate for establishing repeatability estimates of sacha inchi, due to the cyclical nature of the crop. Superior genotypes of the species can be selected for yield-related traits with about 90% accuracy, from 5 harvests (months) onwards. To ensure this accuracy level, it would be necessary to evaluate a minimum of 5 and 25 fruits to determine mean fruit weight and number of seeds per fruit, respectively, and 39 seeds would be required to evaluate the biometric traits.

ABSTRACT Knowledge about associations between traits is fundamental for plant breeding, since indirect selection can accelerate the development of promising genotypes. This study assessed the magnitude of associations between agronomically important traits in fisális (Physalis peruviana L). The experiment was conducted in Lages, Santa Catarina, and the treatments consisted of six fisális populations. The experiment was arranged in a randomized block design, with two replications and seven plants per plot. The correlations between traits were estimated based on the Pearson correlation coefficients and partitioned into direct and indirect effects through path analysis. Fruit weight was positively correlated with number of seeds (0.874), equatorial fruit diameter (0.738) and polar fruit diameter (0.672). By path analysis, number of seeds was identified as the trait with the highest direct contribution to fruit weight. The high phenotypic correlations between the equatorial and polar fruit diameters with fruit weight were mainly due to the indirect effect via number of seeds (0.505 and 0.459). The selection for heavier fisális fruits was strongly influenced by number of seeds, i.e., this trait should be taken into account for selection.

An experiment was conducted during the Monsoon season of 2020 to evaluate twenty genotypes of okra for agro-morphological traits collected from Krishi Vigyan Kendra (KVK) for yield and its contributing characters under field conditions at Jawali, District Kangra, Himachal Pradesh. High significance of analysis of variation showed the existence of large variability among the genotypes. The experiment was laid out in randomized block design with three replications and 10 plants/row. Highest GCV and PCV was found for 100 seed weight followed by days to first flowering node, yield per plant. While the lowest was observed for fruit girth, plant height and fruit length which determines the negligible influence of environment on the different traits. High broad sense heritability was observed for days to first flowering node and genetic advance was recorded highest for yield per plant. Average fruit weight, fruit length and fruit girth were in positive and significant relationship with yield per plant. Principal component analysis revealed the first four major principal components having Eigen value >1 which contributed 82.693% of the total variation. Cluster analysis suggested that the hybridization of cluster I with cluster II would be beneficial for developing varieties in different parts of India because of the variation present between both the clusters.

ABSTRACT In Brazil, sacha inchi oil is produced by hand from plant materials with no breeding or detailed information about the chemical composition of seeds. In addition, most of the current information on the agronomic traits of this species originates from research carried out in the Peruvian Amazon. In order to promote the research and cultivation of sacha inchi in the Brazilian territory, this study aimed to analyze, in the central Amazon region, different accessions of this oilseed for characteristics of production and quality of fruits and seeds, as well as to estimate genetic parameters, through mixed models, with identification of superior accessions, for breeding purposes. A total of 37 non-domesticated accessions were evaluated in a randomized block design, with five replications and two plants per plot. The average oil content in seeds was 29.07 % and unsaturated fatty acids amounted to 91.5 % of the total fat content. For the yield traits, the estimates of individual broad-sense heritability were moderate (~0.33), while the heritability based on the average of progenies resulted in a selective accuracy of approximately 0.85. The use of the selection index provided simultaneous gains for yield traits (> 40 %) and oil yield. A high genetic variability was observed for the main traits of commercial interest for the species, as well as promising perspectives for the development of superior varieties for agro-industrial use.

ABSTRACT In a collection of costeño peppers conserved by indigenous producers from the municipalities of Santa Maria Tonameca and Santo Domingo de Morelos, Oaxaca, Mexico, a description and classification of agromorphological variation was undertaken by characterization of 46 populations in a greenhouse distributed under complete randomized block design with three replicates. Days to first flowering, plant and fruit traits and yield per plant were evaluated. Significant differences were detected for all traits except for plant height at 120 days after planting. In a principal component analysis, the variables of green and dry weight of 15 fruits, average fruit weight, number of fruits and yield per plant were the characteristics with major descriptive value for the total phenotypic variance. In addition, two patterns of agromorphological variation were determined; for productivity, one was highly variable and integrated with pepper populations from La Oscurana, Villa Unión and San Juanito communities, and the other was integrated with less variable populations, such as those from Las Pilas. These phenotypic patterns were confirmed in a cluster analysis, where five phenotypic groups were statistically significantly different. Complementarily, an inverse relationship was determined between number of fruits per plant and average fruit weight in ten populations that presented high agronomic potential; a yield greater than 500 g per plant, more than 100 fruits per plant and an average weight greater than 3.9 g per fruit were detected.

With the objective to determine correlations between yield and principal components of variation of cantaloupe genotypes, in Ramos Arizpe, Coahuila, 12 genotypes were established, in a Complete Randomized Block design with four replications. An experimental plot of two rows five meters long sown at double hill. The genotypes studied were: hybrids: Primo, Pronto, Challenger, Cheyenne, Hi-Line, Cruiser, Durango, Apache, Laguna, Caravelle and Main Pack, and the variety Top Mark, as a control. The variables evaluated were: yield (11 variables: quantitative and qualitative); phenology (three variables); agroclimatic (five variables) and physiologicals (four variables); significant and negative correlations (p<0.05) were found between yield and earliness, mean fruit weight, number of fruits, and between fruit number and fruit lenght. The most correlated physiological variables were photosynthesis and water use efficiency. With the principal component analysis up to the component three 65 % of variance is explained. Component one showed a high value on yield, weight and size characteristics, and called as “Yield Quantitative Characteristics”. In component two, “Earliness Component” showed the higher variations. Component three to six, explain similar proportions the other variables, being the sixth where was found the highest Photosynthesis. Multiple linear regression was significant (p<0.057), due to field conditions, can be considered adequate. Yield in t/ha is explained by a multiple linear equation (r2=0.99) of 10 variables.

The objective of this study was to estimate simple and partial coefficients of correlation, as well as to divide their effects into direct and indirect using path analysis for custard apple tree traits. Twenty half-sibling progenies were evaluated in a randomized block design with five replicates, and plots consisting of four plants. Six traits were evaluated in the first cropping season (mean number of seeds per fruit and mean weight of the pericarp, pulp, pedicel, seeds per fruit, and the whole fruit), while five traits were evaluated in the first three cropping seasons (mean fruit length and width, total number of fruits ha-1, mean fruit weight (in both types of analyses), and fruit yield in kg ha-1). The results of this work led to the conclusion that doing selection based on simple correlation estimates may not be convenient, since not always a cause and effect relationship can be verified between two traits. Positive correlations were obtained between number of seeds and seed weight, and between number of fruits and yield. The greatest direct effects were those obtained for pulp weight on fruit weight and for mean number and weight of fruits on fruit yield. The most important indirect effects were obtained for number of seeds and pericarp weight, obtained via pulp weight, on fruit weight, and for fruit length and width, obtained via mean fruit weight, on fruit yield.

ABSTRACT The low fruit set is one of the main factors leading to poor yield of pear orchards in Brazil. Ethylene is associated with abscission of flowers and fruitlets. Then, the application of ethylene synthesis inhibitors, such as AVG, is a potential tool to increase fruit set of pears. The objective of this study was to evaluate the effect of AVG, sprayed at different rates and timings, on fruit set, yield and fruit quality of ‘Rocha’ pear. The study was performed in a commercial orchard located in the municipality of São Joaquim, SC, during the growing seasons of 2014/2015 and 2015/2016. Plant material consisted of ‘Rocha’ pear trees grafted on quince rootstock ‘BA29’. AVG was tested at different rates (60 mg L-1 and 80 mg L-1) and timings [full bloom, one week after full bloom (WAFB), and two WAFB), either alone or in combination. The experiment was arranged in a randomized block design, with at least five single-tree replications. The fruit set, number of fruit per tree, yield, estimated yield, fruit weight, return bloom, and fruit quality attributes were assessed. Fruit set and yield were consistently increased by single applications of AVG at 60 and 80 mg L-1 at both one and two weeks after full bloom, without negatively affecting fruit quality attributes and return bloom.
