RESISTANCE TO FUNGI
A watermelon plant and seed, namely of Citrullus lanatus, which are resistant to fungi, including Watermelon Powdery Mildew (PM), comprising in their genome introgressed sequences from Citrullus lanatus var. Citroides conferring resistance to the fungi. More specifically, the invention also discloses molecular genetic markers, linked to the dominant genetic locus conferring resistance to fungi characterized by a resistance to powdery mildew (PM) race 1 and race 2 as quantified by a tolerance of less than about 3.5 on the Tetteh scale, and having properties such that seedless fruits are produced with a total soluble solid (TSS) of at least 10%, flesh firmness of between 60 and 80 on a scale of 10 to 90, where 10 indicates very soft flesh and 90 indicates a very firm flesh, and a flesh color selected from the group consisting of yellow, orange or red fruit flesh color, preferably dark red.
METHODS OF IDENTIFYING AND SELECTING MAIZE PLANTS WITH RESISTANCE TO ANTHRACNOSE STALK ROT
Compositions and methods useful in identifying and/or selecting maize plants that have anthracnose stalk rot resistance are provided herein. The resistance may be newly conferred or enhanced relative to a control plant. The methods use maize markers on chromosome 10 to identify, select and/or construct resistant plants. Maize plants generated by the methods also provided.
Resistance in plants of <i>Solanum lycopersicum </i>to the tobamovirus tomato brown rugose fruit virus
The invention relates to a Solanum lycopersicum plant resistant to Tomato Brown Rugose Fruit virus comprising in its genome the combination of the Tm-1 resistance gene on chromosome 2, and at least one quantitative trait locus (QTL) chosen from QTL3 on chromosome 11, QTL1 on chromosome 6 and QTL2 on chromosome 9, that independently confer to the plant foliar and/or fruit tolerance to TBRFV, wherein said QTLs are present in the genome of a plant of the seeds HAZTBRFVRES1 NCIMB accession number 42758. The combination of at least one of these QTLs with the Tm-1 gene delays, reduces or inhibits the replication or multiplication of the virus in the plants of the invention. The invention is also directed to parts of these plants with TBRFV resistance phenotype, as well as progeny, to the use of these plants for introgressing the resistance in another genetic background, as well as to different methods for obtaining tomato plants or seeds with increased resistance to Tomato Brown Rugose Fruit virus.
High yield sesame
High yield sesame plants and parts thereof are provided. Phenotypic and genotypic analysis of many sesame varieties was performed to derive markers for phenotypic traits that contribute to high yield, and a breeding simulation was used to identify the most common and most stable markers. Examples for such phenotypic traits include the number of capsules per leaf axil, the capsule length, the height to first capsule and the number of lateral shoots. Following verification of trait stability over several generations, markers and marker cassettes were defined as being uniquely present in the developed sesame lines. The resulting high yield, shatter-resistant sesame lines can be used to increase sesame yield for its various uses.
METHODS FOR GENOTYPING HAPLOID EMBRYOS
The invention provides novel methods to genotype haploid embryos using molecular assays. For example, quantitative methods for genotyping are provided. The methods provided also include providing a plurality of haploid kernels, determining the genotype of the haploid embryo of said kernels by distinguishing its genotype from the endosperm genotype, selecting a kernel having a desired genotype and producing doubled haploid plant from the selected kernel.
METHODS FOR IDENTIFYING AND SELECTING MAIZE PLANTS WITH RESISTANCE TO NORTHERN CORN LEAF BLIGHT
The present invention relates to maize plants having increased pathogen resistance or tolerance, in particular increased resistance or tolerance to pathogens causing Northern Corn Leaf Blight, i.e. Exserohilum turcicum. Such maize plants are characterized by particular molecular markers The invention further relates to methods for identifying such maize plants.
Methods and compositions for identifying verticillium wilt resistant sunflower plants
The present invention relates to methods for identifying sunflower lines having increased resistance to Verticillium wilt, and identification of genetic markers linked to gene(s) conditioning such increased disease resistance. The present invention also relates to methods of breeding sunflower plants from lines having increased Verticillium wilt resistance by marker-assisted selection, compositions including nucleic acid probes or primers which are useful for such marker assisted selection, and plants and plant parts produced by such methods.
Genetic loci associated with reproductive growth phenotypes in soybean and methods of use
Various methods and compositions are provided for identifying and/or selecting a soybean plant or soybean germplasm with one or more preferred or desired reproductive growth phenotypes. In certain embodiments, the method comprises detecting at least one allele of one or more marker locus within or linked to a QTL associated with days to initiation of flowering. In other embodiments, the method additionally comprises detecting at least one allele of one or more marker locus within or linked to a QTL associated with days to maturity. In further embodiments, the method comprises crossing a selected soybean plant with a recurrent soybean parent plant. Further provided herein are marker loci, marker alleles, primers, probes, and kits suitable for identifying and/or selecting soybean plants or soybean germplasms with one or more reproductive growth phenotypes.
