“…Figure 4 presents the values of sij corresponding to the 28 best combinations (10% of the topcross) in Capão Bonito, São Paulo State, Brazil. Camacho, Scapim, Senhorinho, and Conrado (2015), evaluating the SCA for EL and ED, found lower sij values than those of this study by using model 4 proposed by Griffing (1956). The hybrid combination 63 × IAC12 showed high predicted sij values for EL, ED, and GY.…”

Evaluation of combined ability can eliminate lines that are inefficient and enable the subsequent program steps to be more successful. The objective of this study was to predict the general (gi) and specific (sij) combination ability of popcorn S1 progenies for early selection. A total of 288 topcrosses were performed under a randomized complete block design with two replicates at two sites (Campinas and Capão Bonito, São Paulo State, Brazil). Diallel analyses were performed using mixed models and the maximum likelihood restricted/best unbiased linear prediction method. Evaluated traits included grain yield (GY; kg ha-1), weight of 100 grains (g), and popping expansion (PE; mL g-1). Ear components were also evaluated, including ear length, ear diameter (cm), and the number of grain rows (unit). The S1 progeny 32 presented the highest gi for GY in Campinas, whereas progeny 46 presented the highest gi for GY in Capão Bonito. The S1 progeny, 114 was an important parent for the popcorn breeding program, because it presented high gi for the traits of agronomic interest at both sites. Combination 86×IAC12 exhibited a high sij, and the 86 parent presented the second-highest gi for PE in Campinas, and it should be used for high PE genotypes

“…The results from the GCA and SCA analysis using diallelic models are usually interpreted regarding genetic effects; the GCA is predominantly associated with the additive effects and the SCA with the non-additive effects of the genes (Silva et al 2002, Camacho et al 2015. This interpretation seemed inappropriate in the present case because the variable was a composite variable and a large number of diverse primary variables were analyzed in the selection.…”

Limited number of sweet corn varieties specifically bred for organic cropping system has brought about the organic sweet corn growers use hybrid varieties supposedly grown under high agrochemical inputs cropping system. The objective of the present study was to evaluate the performance of sweet corn inbred lines and to estimate the genetic parameters as to the development of varieties suitable for organic cropping systems. Eight inbred lines of S5generation previously selected for yield and adaptability to organic conditions were evaluated in a randomized block design with seven replications. Performances and genetic parameter estimation were addressed to plant height, the number of leaves, stalk diameter, ear length, ear diameter, kernel row number, kernel number per row, and ear yield per plant. Significant variations were found among the inbred lines for all traits studied. Similar features were also found within the inbred line, except stalk diameter showed non-significant within-line variation. Evaluation of mean values indicated that CAPS 2 exhibited the best plant growth performances and produced reasonably high ear yield. CAPS 5 produced the highest ear yield along with superior ear length, ear diameter, and kernel row number. Broad sense heritability (h2B) were ranged from low to moderate with the higher estimates found on ear length (0.43) and ear yield per plant (0.40). Based on the estimates of genetic advance as percent of the population mean (GAM), moderate improvement can be expected from ear length (13.37%) and ear yield per plant (20.86%) by selecting the top 5% of the inbred line populations.
