The objectives of this research were to increase the number of SSR markers on the ‘Fulghum’ × ‘Norline’ recombinant inbred population genetic map and to scan for quantitative trait loci (QTL) associated with winter field survival, crown freezing tolerance, vernalization response, and heading date. New SSR markers were developed from ‘Kanota’ and ‘Ogle’ genomic DNA libraries enriched for eight microsatellite motifs. New primers were evaluated for amplification, reproducibility, and polymorphism in 11 oat lines. Simple sequence repeat markers showing high‐quality polymorphism between Fulghum and Norline were subsequently examined in 128 recombinant inbred lines. Sixty‐five new SSR, four single nucleotide polymorphism (SNP), and one cleaved amplified polymorphic sequence (CAPS) markers were added to the Fulghum × Norline linkage map. This brought the total number of markers mapped on the population to 101. Phenotypic data for winter hardiness component traits in the population were obtained in previous field and controlled chamber experiments. All previously mapped markers and new SSR markers were evaluated and QTL identified. Marker loci on linkage group FN1_3_38 accounted for multiple QTL associated with winter hardiness component traits. The addition of new SSR markers to the Fulghum × Norline map in regions with winter hardiness component trait QTL will enhance marker assisted selection for these important traits.}, number={2}, journal={CROP SCIENCE}, author={Maloney, P.

The objective of this study was to identify quantitative trait loci (QTL) for crown freezing tolerance in the ‘Kanota’ × ‘Ogle’ recombinant inbred line (RIL) mapping population and to examine their relationship with other winter hardiness traits. One hundred thirty‐five RILs were evaluated for crown freezing tolerance in a controlled environment. Previously published molecular marker and linkage map information was used for QTL detection. Seven QTL and four complementary epistatic interactions were identified that accounted for 56% of the phenotypic variation. Ogle contributed alleles for increased crown freezing tolerance at three loci, while Kanota contributed alleles for increased crown freezing tolerance at four loci. All loci where Kanota alleles increased crown freezing tolerance showed complementary epistasis for decreased crown freezing tolerance with the QTL near UMN13. Two of the major QTL identified were in the linkage groups (LG) associated with a reciprocal translocation between chromosomes 7C and 17, which was previously associated with spring growth habit in oat. The results confirm the importance of the chromosomes involved in the reciprocal 7C‐17 translocation in controlling winter hardiness component traits.}, number={1}, journal={CROP SCIENCE}, author={Wooten, David R. and Livingston, David P., III and Holland, James B. and Marshall, David S. and Murphy, J.

The objectives of this experiment were to evaluate crown meristem freeze tolerance and winter field survival among 94 random F4–derived lines from the cross between the cultivars Wintok (T7C‐17, winterhardy) and Fulghum (non‐T7C‐17, less winterhardy) and to examine the association between these winterhardiness traits and T7C‐17. Crown meristem freeze tolerance was evaluated in a three‐replicate randomized complete block design in controlled environment growth cabinets. Field survival was evaluated in a three replicate randomized complete block design at Laurel Springs, NC during the 1999–2000 season. Greater crown meristem freeze tolerance and greater winter field survival were associated with the presence of T7C‐17. Lines heterogeneous for the translocation had similar levels of crown meristem freeze tolerance and field survival as lines homozygous for the translocation. Twenty‐two percent of the variation in crown meristem freeze tolerance and 27% of the variation in field survival was accounted for by translocation status. The observed frequencies of translocation homozygotes and heterozygotes did not fit the expected frequencies for single factor segregation in the F4 generation. There were almost threefold as many homozygotes with the translocation as homozygotes without the translocation which indicated preferential selection for T7C‐17 during inbreeding. Our results suggested that T7C‐17 might be isolating, in terms of recombination, either a dominant allele or a group of loci conditioning winterhardiness in our population.}, number={1}, journal={CROP SCIENCE}, author={Santos, AG and Livingston, DR and Jellen, EN and Wooten, DR and Murphy, JP}, year={2006}, pages={203–208} }
