“…Laurentin (2011) attributes these results to the influence of the maternal genotype. Similar results have been reported in several species and traits; for example, in interspecific hybrids of Passiflora for vegetative traits (Primot et al, 2005), or in the composition of fatty acids in soybean (Glycine max L.) seeds (Gilsinger et al, 2010).…”

-The objective of this work was to determine the inheritance mode of seed coat color in sesame. Two crosses and their reciprocals were performed: UCLA37 x UCV3 and UCLA90 x UCV3, of which UCLA37 and UCLA90 are white seed, and UCV3 is brown seed. Results of reciprocal crosses within each cross were identical: F 1 seeds had the same phenotype as the maternal parent, and F 2 resulted in the phenotype brown color. These results are consistent only with the model in which the maternal effect is the responsible for this trait. This model was validated by recording the seed coat color of 100 F 2 plants (F 3 seeds) from each cross with its reciprocal, in which the 3:1 expected ratio for plants producing brown and white seeds was tested with the chi-square test. Sesame seed color is determined by the maternal genotype. Proposed names for the alleles participating in sesame seed coat color are: Sc 1 , for brown color; and Sc 2 , for white color; Sc 1 is dominant over Sc 2 .Index terms: Sesamum indicum, export market, maternal effect, seed color, sesame breeding. Herança da cor do tegumento em sementes de gergelimResumo -O objetivo deste trabalho foi determinar o padrão de herança da cor do tegumento da semente de gergelim. Dois cruzamentos com recíprocos foram feitos: UCLA37 x UCV3 e UCLA90 x UCV3, dos quais UCLA37 e UCLA90 apresentam sementes brancas e UCV3, sementes marrons. Os resultados dos cruzamentos recíprocos, dentro de cada cruzamento, foram idênticos: as sementes F 1 mostraram o mesmo fenótipo que o parental materno, e as F 2 resultaram no fenótipo semente marrom. Esses resultados são consistentes apenas com o modelo no qual o efeito materno é responsável por essa característica. Esse modelo foi validado pelo registro da cor do tegumento da semente de 100 plantas F 2 (sementes F 3 ) para cada cruzamento com o seu recíproco, em que a proporção esperada de 3:1 para plantas produzindo sementes marrons e brancas foi testada com o teste do qui-quadrado. A cor do tegumento da semente de gergelim é determinada pelo genótipo materno. Os nomes propostos para os alelos participantes na determinação da cor da semente de gergelim são: Sc 1 , para a cor marrom; e Sc 2 , para a cor branca; Sc 1 é dominante sobre Sc 2 .Termos para indexação: Sesamum indicum, mercado de exportação, efeito materno, cor da semente, melhoramento de gergelim.

“…The value of the oleic acid QTLs on Gm05, Gm17, Gm18, and Gm19 previously reported (Monteros et al 2008) were re-confirmed in two additional genetic backgrounds by (Gilsinger 2008) who demonstrated a continual increase in oleic acid content as the number of integrated mid-oleic acid QTL loci increased. These findings confirm the role of these QTLs in the soybean oleic acid phenotype.…”

Increasing the amount of oleic acid in soybean oil would reduce the need for hydrogenation, a process that creates unhealthy trans fatty acids. A previous study mapped six oleic acid quantitative trait loci (QTLs) from N00-3350 (*550 g kg -1 oleic acid) on soybean chromosomes (Gm) 5, 17, 18, and 19, which corresponds to linkage groups (LG) A1, D2, G, and L, respectively. The objectives of this study were to develop high throughput assays to detect single nucleotide polymorphism (SNP) markers associated with these oleic acid QTLs. Several candidate genes that are putatively responsible for the oleic acid phenotype in N00-3350 were identified by BLAST searches against the soybean genomic assembly using the sequences of fatty acid synthesis genes from soybean and Arabidopsis. Putative accC-2 and KAS I genes were located in the region of the cqOle-001 on Gm05 (LG-A1). A putative KAS I gene was located in the region of the cqOle-003 on Gm18 (LG-G) and a putative accB-1 gene was located in the region of the cqOle-004 on Gm18 (LG-G). These fatty acid candidate genes and sequence-tagged sites were used to identify SNPs between N00-3350 and 'Boggs'. Based on these SNPs, seven SimpleProbe probes for melting curve analysis were developed to rapidly identify the alleles from the mid-oleic acid soybean line N00-3350 at the desired loci. These assays provide a highthroughput and rapid SNP genotyping method which can be used to accelerate the development of midoleic acid content soybean cultivars.

“…Reciprocal effects on oleic acid content have been reported by Vares et al (2004). Maternal effect on fatty acids was also found in other oil crops such as canola and soybean (Thomas and Kondra, 1973;Erickson et al, 1988;Gilsinger et al, 2010).…”

“…Within the second sowing date, environment could mask maternal effect and so reciprocal hybrids are equal. When parents displaying small differences in fatty acid composition are crossed, environment could easily mask any maternal effects (Gilsinger et al, 2010). Different response magnitude between 342mt and its 342mt × R978 hybrid could be related to a different duration of F to PM.…”

“…Different response magnitude between 342mt and its 342mt × R978 hybrid could be related to a different duration of F to PM. It is important to note that the magnitude of the maternal effect could be the result of some number of morphological or physiological processes, all of which could be controlled by genes in the nucleus or cytoplasm (Gilsinger et al, 2010).…”

High oleic trait has been rarely studied in reciprocal crosses and in most of these cases the maternal effect on the content of unsaturated fatty acids has not been identified. The aims of this study are: i) to check if any maternal effect on oleic acid content is present in high oleic mutants and (ii) if maternal effect and environment conditions could modify the 90% threshold for oleic acid content. Two high oleic inbred lines with different origins were evaluated: 342mt, a selection derived by Ha 342 USDA (maintainer) and line R978 (male fertility restorer, branched) selected by University of Udine and their reciprocal crosses (R978 × 342mt and 342mt × R978). The two inbred lines respond differently to the same environmental conditions. Reciprocal hybrids showed a different accumulation pattern on the first sowing date, and they showed the same response as their female parent. There is a maternal effect in the early stages of the seed filling phase. Low temperature increased linoleic acid and decreased oleic acid at 13 DAF only in 342mt inbred line and in the 342mt × R978 hybrid. High oleic inbred lines with different genetic backgrounds respond differently to the same environmental conditions. It was determined that there was the importance of female parental line choices in breeding to obtain hybrids insensitive to environmental conditions and with a stable oleic acid content over 90%. For the first time a maternal effect on temperature response was found in high oleic sunflower.
