Efforts to improve the yield of kidney beans can be done through plant breeding programs, namely through introduction and selection activities. Selection is carried out to identify superior genotypes and will be effective if the relationship and influence between the characters are known. The research was conducted to study the closeness of the relationship between the characters of introduced kidney beans from Timor Leste and their direct and indirect effects through correlation and path analysis. This research was conducted at the Universitas Djuanda Experimental Garden, Ciawi, Bogor, in August-November 2020. The research design used was a randomized complete block design (RCBD) with accession as a factor and repeated 4 times. The results showed that the number of pods character had the highest correlation coefficient value on seed weight per plant as a yielding character for kidney beans with a value of r = 0.91 *. Besides, the number of pods also had a high direct (0.35) and indirect (0.91) effect through the characters of the number of seeds per pod (0.8) and the number of branches (0.3).

Abstract:The objective of this work was to characterize the performance of elite wheat genotypes from different Brazilian breeding programs for traits associated with grain yield and preharvest sprouting. The study was conducted in 2010 and 2011 in the municipality of Capão do Leão, in the state of Rio Grande do Sul, Brazil, in a randomized complete block design with three replicates. Thirty-three wheat genotypes were evaluated for traits related to preharvest sprouting and grain yield. The estimate of genetic distance was used to predict potential combinations for selection of plants with high grain yield and tolerance to preharvest sprouting. The combined analysis of sprouted grains and falling number shows that the TBIO Alvorada, TBIO Mestre, Frontana, Fundacep Raízes, Fundacep Cristalino, and BRS Guamirim genotypes are tolerant to preharvest sprouting. Combinations of TBIO Alvorada and TBIO Mestre with Fundacep Cristalino show high potential for recovering superior genotypes for high grain yield and tolerance to preharvest sprouting.

A field experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka with a view to study character association and path analysis in six strawberry genotypes. The trial was laid out in a Randomized Complete Block Design with three replications. Data on crown height, number of flower buds per plant, number of flowers per plant, number of fruits per plant, length and breadth of fruit and fruit yield per plant were collected. All the characters showed significant correlation with fruit yield. Path analysis revealed that crown height, number of flowers per plant and length of fruit had the positive direct effect on yield per plant. Number of flower buds per plant, number of fruits per plant and breadth of fruit had negative direct effect on yield per plant.

Knowing the cause and effect among two or more traits can help to increase the selection accuracy of superior genotypes. The main objective of this study was to evaluate the cause and effect relationship between expansion volume and kernel size in popcorn hybrids using path analysis and Bayesian network. A total of 41 popcorn hybrids were evaluated through a randomized complete block design (RCBD) with two replicates in the city of Jaboticabal, Brazil. The assessed traits were grain length (GL),grain thickness (GT), grain width (GW), caryopsis roundness index (CRI), mass of 50 grains (MG), and expansion volume (EV). Measurements were performed on individual grains, using three 50-grain samples from each plot. Pearson’s correlation coefficient, path analysis and Bayesian network were estimated. A negative correlation was detected among EV and the traits, except for GT. Path analysis indicated that MG has a direct and positive effect on EV and the negative correlation observed is mainly due to the indirect effects by GL and GT. Bayesian networks did not detect a direct association between kernel size and expansion volume while indicating that GT is the only trait that can affect popcorn flake size.

The Relationship

Harrowing is one of the most popular mechanical methods to control weeds. Nevertheless, the relationship between the effect of different harrowing intensities using spike-tooth harrow in barley-pea intercrop on the yield and mycoflora of grains has not yet been studied. Therefore, the aim of this study was to assess the effect of harrow intensity using spike-tooth harrow in barley-pea mixture on the mycological quality of harvested grains, grain yield, as well as influence of barley and pea grain moisture on the abundance of fungi. The field experiment was carried out during 2010–2012, and it was conducted using a randomized complete block design with four replicates. Weed control was mechanical and chemical. In this study, we have shown that harrowing in barley-pea intercrops does not reduce the yield of either mixture components, both with respect to grain quantity or mycological quality after harvest, compared to controls—without harrowing and the herbicide MCPA (2-methyl-4-chlorophenoxyacetic acid). However, increasing the intensity of harrowing did not result in a consistently larger crop yield or reduction in fungal abundance in the grains. The grains’ internal structures and surface of both tested components of the mixture were colonized to a large extent by cosmopolitan fungi, of which Alternaria alternata (Fr.) Keissl. was the most abundant.

Seven mulberry genotypes, namely: Alf-004, Alf-018, Alf-025, S61-011, S61-019, S54-019 and the Batac were evaluated in terms of biochemical parameters along with leaf yield. Parameters viz; moisture content (MC), total carbohydrate (TC), crude fat (CF), ash, crude protein (CP), Total N,P and K along with leaf yield were analyzed using the ANOVA in Randomized Completely  Block Design (RCBD). Further, Evaluation Method Index was used to determine the superior mulberry genotypes. The data revealed that the different genotypes under study vary in their biochemical components where significant variations in all the parameters evaluated except in percent total phosphorus. For the phytochemical analysis, alkaloids, carbohydrates, glycosides, saponins, phytosterols, phenolic compounds, flavonoids and proteins were detected. Based on the evaluation index value, the identified and selected superior genotypes having higher leaf biochemical composition were Alf-004, Alf-018 and Alf-025.

Cashew (Anacardium occidentale L.) is an important tropical cash crop cultivated in Ghana. It provides livelihood for about 200,000 people and contributes 6.1% to Ghana’s gross domestic product (GDP). Four Brazilian dwarf accessions were introduced to improve nut yield. Objectives of this study were to (1) assess the agronomic performance of the accessions across two contrasting ecologies, (2) determine environmental influence on juvenile growth, (3) determine the relationship between early vegetative growth and yield and (4) explore heritability and genetic advance for the measured agronomic traits. The experiment was laid out in a randomized complete block design with 3 replications. Results revealed significant (p < 0.05) environmental influence on growth and yield of cashew. Transitional savanna agro-ecology is more suitable for cashew growth and development. Crop year, location and crop year × location interactions also influenced most of the agronomic traits. Early growth characteristics alone were not enough to predict yield. Genotype B2 ranked highest yielding across the agro-ecologies. Moderate to high heritability and genetic advance estimates were observed for nut yield, plant height and girth, an indication of variability among accessions needed for cashew improvement in Ghana.

Introduction: Marital infidelity is a major factor that affects the strength, durability, and mental health of families. The present study aimed to investigate the mediating role of marital satisfaction in the causal relationships between forgiveness and the feeling of loneliness with attitudes toward marital infidelity in married students. Materials and Methods: This causal-correlational and field study was conducted on 211 married students who were selected from Ahvaz Branch, Islamic Azad University, Ahvaz, Iran, during the academic year 2018-2019 through convenience sampling. The data were collected using the Interpersonal Forgiveness Inventory, Russell’s Loneliness Scale, Whatley’s Attitude towards Infidelity Scale, and ENRICH marital satisfaction questionnaire. Furthermore, the data analysis was performed in SPSS software (version 24) through descriptive and inferential statistics, including mean±SD, Pearson’s correlation, and path analysis. Results: A direct and negative relationship was observed between forgiveness and attitudes toward marital infidelity (β=-0.181, P=0.013); feeling of loneliness and marital satisfaction (β=-0.252, P=0.001); and marital satisfaction and attitudes toward marital infidelity (β=-0.418, P=0.001). Furthermore, there was a direct and positive relationship between forgiveness and marital satisfaction (β=0.517, P=0.001). Eventually, there was no significant direct relationship between the feeling of loneliness and attitudes toward marital infidelity (β=-0.029, P=0.652). The results of path analysis indicated that marital satisfaction had a mediating role in the relationship between forgiveness and attitude towards marital infidelity (β=-0.165, P=0.001), as well as the association between the feeling of loneliness and attitude towards marital infidelity (β=0.138, P=0.002). Conclusion: The results showed a good fit for the proposed model in this study. Moreover, marital satisfaction played an important role in the relationship between forgiveness and the feeling of loneliness with the attitude toward marital infidelity.

Crop Research

Experimental accuracy in crop research is directly affected by the size of plots. For this reason, researchers use empirical knowledge to determine plot size. There are also other important aspects for determining ideal plot size. These include the type of crop and the use, or not, of borders. The objective of this research was to verify the necessity of including border material in the value of cultivation and use trials in breeding programs of upland rice and to evaluate the experimental accuracy with and without the inclusion of borders. The research was conducted in an experimental area at the Federal University of Lavras, located in the State of Minas Gerais, during three harvests (2014/2015, 2015/2016, 2016/2017). Thirteen upland rice strains and methods of evaluation (useful area and border) were evaluated. A randomized complete block design with three replications was used to evaluate grain yield. Individual analyses of variance were performed considering the useful areas and the borders for the three agricultural years. A joint analysis was also performed with the use of a subdivided plot involving the location of the harvest in terms of the useful area and border among the rice strains. It was concluded it is necessary to use borders in the value of cultivation and use trials in breeding programs of upland rice as it contributes to the performance and experimental accuracy of research results.

Effect On Yield

Path coefficient analysis was carried out in tropical pumpkin (Cucurbita moschata Duchesne) for yield per plant as a function of number of fruit per plant and weight per fruit, using phenotypic and genetic correlations from two diallels: one using five varieties (variety diallel) and a second using five S1 lines derived from the varieties (line diallel). A randomized complete block design with five replications was used to evaluate 15 genotypes from each diallel, not including reciprocals. Direct effects were 300 to 500% greater than indirect effects in the line diallel. In contrast, direct effects were only 17 to 68% greater than indirect effects in the variety diallel. Effects (direct and indirect) were greater (17 to 500%) when genetic correlations rather than phenotype correlations (42 to 440%) were used in the path analysis. Fruit weight showed a greater effect on yield than did number of fruit, with values between 3.2 to 4.9 times the residual effects. Fruit weight and number of fruit can be used as selection criteria to increase yield in tropical pumpkin.
