“…One of the methods of diallel cross analysis is that presented by Griffing (1956), through which the effects of general combining ability and specific combining ability are estimated (Ramalho et al, 2005). This type of analysis has been used for various traits in common bean, such as seed yield (Mendes et al, 2009), early maturity (Vale et al, 2015), reaction to fusarium wilt (Batista et al, 2016), reaction to white mold (Ferreira et al, 2018), and drought tolerance (Gonçalves et al, 2015), among others. However, reports of its use for reaction to fusarium wilt in field conditions were not found.…”

Diallel analysis and field tests have not been used in selecting for resistance to fusarium wilt in common beans (dry beans, Phaseolus vulgaris). Our goal was to select parents and segregating populations of dry bean (common bean) with black seed coat that are resistant to fusarium wilt and have high yield and high seed weight. Eight common bean cultivars and elite lines with some level of resistance to fusarium wilt based on previous evaluations, were used to make crosses in a complete diallel scheme. The 28 populations obtained were evaluated with two controls in trials in the F 3

“…These genotypes show an upright plant growth and adaptation to direct mechanical harvest, which favors the avoidance from white mold in the field (Paula Júnior et al 2009;Vieira et al 2010;Miklas et al 2013). The combination of morphological and phenological traits with physiological resistance to white mold in the same genotype is the main goal of breeding programs (Miklas et al 2013;Schwartz and Singh 2013;Lehner et al 2015;Ferreira et al 2018).…”

“…Therefore, common bean cultivars combining morphological and agronomic traits that help avoidance of the disease and physiological resistance have been highly demanded by growers. So far, efforts and progress of breeding programs to develop cultivars possessing these traits have not been fully successful in Brazil and worldwide (Miklas et al 2013;Schwartz and Singh 2013;Lehner et al 2015;Ferreira et al 2018).…”

Although different methods of inoculation have been proposed to assess the reaction of common bean to white mold (WM) caused by Sclerotinia sclerotiorum, a thorough comparison among them is lacking. In this study, six approaches were tested to identify the most reproducible and efficient method for discriminating six common bean genotypes of carioca market class based on their resistance to white mold. These included: modified straw test (ST), cotton pad (CP), infected flower on intact plant (IFIP) or on detached leaf (IFDL), and mycelium disc on intact plant (MDIP) or on detached leaf (MDDL). All experiments were conducted in a greenhouse or laboratory in a completely randomized design with four replicates. Several statistics including coefficient of variation (CV), standard deviation, intraclass correlation coefficient (ICC), p value for Bartlett's test for homoscedasticity and sensitivity ratio (SR) were used as criteria for discrimination. The Spearman's correlation coefficient was used to test the association between the methods. Results showed ST as the most suitable for selecting WM-resistant genotypes, followed by the IFIP method.

“…Kaczmarska et al (2016 and reported various values for heterosis and general combining ability (GCA) of strawberry genotypes. In general, the selection of parents is of great importance for exploiting heterosis in food crops such as tomato (Solieman et al, 2013;Amaefula et al, 2014;Reddy et al, 2014;Figueiredo et al, 2015;Kumar and Gowda, 2016), pepper (Singh et al, 2014;Bhutiaet al, 2015;Kaur et al, 2018), eggplant (Singh and Chaudhary, 2018), muskmelon (Singh and Vashisht, 2018) and in common bean (Ferreira et al, 2018;Junior et al, 2018).…”

Background: The possibility of selecting the best genotypes to develop good hybrid varieties of tomatoes, as well as heterosis, potence ratio and correlation of vegetative characteristics, yield and quality in tomato genotypes and their performance under arid region.Methods: Four commercial tomato cultivars (Money Maker, Pakmore VF, Strain-B and Tanshet Star) and two breeding lines (L05960 and TL01899) and their 15 F1 hybrids, using a half-diallel cross, under arid conditions were used to estimate heterosis, potence ratio and correlation coefficients among all possible pairs of important tomato traits.Result: various degrees of dominance effects for some traits were detected in the general performances of the F1 hybrids, while, other traits illustrated the presence of partial- to under-recessiveness. Heterosis percentages reflected positive desirable effects in ten F1 hybrids for some traits. Most F1 hybrids outperformed their respective parents for fruit set, fruit length, fruit diameter, total soluble solids, fruit dry weight, number of fruits per plant and total fruit yield per plant. Some of the genotypes (i.e., parents and/ or hybrids) offer opportunities as a genetic source of heat tolerant breeding genetic material adapted to high temperature under the arid conditions reported in this study. Significant positive and desirable correlations were found between 41 possible pairs of traits, whereas significant negative and undesirable correlations were found between 13 possible pairs of the traits.
