Additive and dominance contrasts were likewise estimated for each background genotype and across all background genotypes.
The separation of the effect of background genotype from that of the ol genes in this study suggests that the ol genes are not the only ones affecting fatty acid profiles in peanuts.
There was interaction between the effects of the ol gene and the background genotype of the population for concentrations of palmitate, oleate, linoleate, total [C.sub.18] species, and total saturates (Table 2).
The objectives of this study were to determine whether the distributions of fatty acid contents conformed to simple dominance, to quantify the effect of the rare ol gene on oleate, linoleate, and other fatty acids, and to determine whether the effect of the ol gene was uniform across background genotypes.
The detrimental effect of the 1BL.1RS translocation on dough properties can be mitigated by rigorous selection of the background genotype (Carver and Rayburn 1995; Lee et al., 1995).
Variation among transgenic lines in each background genotype was still evident at the end of the experiment (Fig.
Analysis of variance (not shown) for symptom scores and virus accumulation (ELISA readings) at 21 DPI indicated no significant differences among background genotypes. Differences among transgenic lines within genotypes were significant for all observed traits.
brachytic stem type is dependent on background genotype.
The interaction between this resistance benefit and crosses and the interaction of this resistance benefit x pair within crosses were not significant (Table 4), indicating the improvements in seed coat mottling in late planting coming from SW resistance were independent of background genotype. In addition, there was a significant correlation between seed coat mottling and the incidence of SMV infection at [R.sub.1] (r = 0.44, P [is less than] 0.01), implicating early SMV infection as a factor causing mottled seed coats.
Because the resistance to SMV provided an average benefit for yield in late planted environments that was independent of the background genotype and because the incidence of SMV infection at [R.sub.2] was greater than 25% in late plantings at seven of 10 environments, we recommend incorporating resistance to SMV into soybean cultivars which would be used in a double-cropping production system.
The expression of specific resistance genes and the accompanying yield response may be affected by background genotypes (Schafer, 1971).
6c, the genotype combination AABBCC has the highest performance (line plot) but genotype aa has the highest value when averaged across all background genotypes for genes B and C (vertical bars).
