Abstract:
... Most broccoli cultivars are sensitive to high temperatures during the early stages of floral development causing a severe decline of head quality or even complete lack of head formation under superoptimal crop production temperatures. Several heat tolerant lines have been developed in recent years but there have been few studies of the genetic basis of this complex, polygenic trait. A doubled hapl ...

Abstract:
... The root-knot nematode Meloidogyne graminicola is a serious pest in rice affecting production in many rice growing areas. Natural host resistance is an attractive control strategy because the speed of the parasite’s life cycle and the broad host range it attacks make other control measures challenging. Although resistance has been found in the domesticated African rice Oryza glaberrima and the wil ...

Upland cotton, Gossypium hirsutum L., is an important fiber crop that is grown in warmer climates in over seventy-five countries through-out the world and accounts for over 90% of world production. In this study we assessed the genetic diversity and population structure of 1115 day-neutral conversions of G. hirsutum L. landrace accessions (DNCA). One-hundred-thirty-four genome wide simple sequence ...

Abstract:
... Starch branching enzymes (SBEs) incorporate α-1,6-branched glucosidic linkages into α-1,4-glucan chains. Rice has three SBE isoforms (SBEI, SBEIIa, and SBEIIb), which differ in the amylose chain lengths that they transfer to amylopectin. SBEI mutants characterized to date have had little or no effect on starch structure or content. In this study, TILLING by sequencing was employed to identify SBEI ...

Most cotton in the world is planted to Upland cultivars. Many attempts have been made, over a considerable number of years, to introgress fiber quality alleles from G. barbadense into Upland. However, intro ...

Abstract:
... The Glycine max (L.) Merr. Cultivar Waseshiroge is highly resistant to several races of Phytophthora sojae in Japan. In order to determine which Rps gene might be present in Waseshiroge, 15 differential cultivars were challenged with 12 P. sojae isolates. None had a reaction pattern identical to that of Waseshiroge, indicating that Waseshiroge may contain a novel Rps gene. In order to characterize ...

Abstract:
... Kernel texture is an important characteristic for both the milling and the end-use quality of wheat (Triticum aestivum L.). Gene sequence variation and mutations to the two puroindoline genes (Pina and Pinb), located at the Ha locus on chromosome 5DS, account for the majority of variation in wheat kernel texture. Other factors also influence kernel texture, including effects associated with differ ...

Abstract:
... Heading date is an important trait that determines wheat adaptation to environments. A recombinant inbred line (RIL) population derived from CI 13227 x Suwon 92 was employed to tag the quantitative trait locus (QTL) for early heading in Suwon 92. This population was phenotyped for heading date in 1994, 1995, and 1997, and analyzed with AFLP and SSR markers. Two AFLP markers (XGCTG.CGCT118 and XGCT ...
