The present invention is in the field of plant breeding and aphid resistance. More specifically, the invention includes a method for breeding soybean plants containing quantitative trait loci that are associated with resistance to aphids, Aphis glycines. The invention further includes method for monitoring the introgression quantitative trait loci (QTL) conferring aphid resistance into elite germplasm in a breeding program.

Plant cell fate and development is altered by treating cells with cellular reprogramming factors. Embryogenesis inducing embryogenesis factor genes and/or morphogenic developmental genes are used as cellular reprogramming factors, specifically comprising polypeptides or polynucleotides encoding gene products for generating doubled haploids or haploid plants from gametes. Maize microspores treated by contacting the isolated cells with an exogenous purified, recombinant embryogenesis inducing embryogenesis factor gene products and/or morphogenic developmental gene polypeptide results in embryogenesis. The gametes of a maize plant develop into embryoids when transformed with a genetic construct including regulatory elements and structural genes capable of acting in a cascading fashion to alter cellular fate of plant cells. Embryogenesis factor proteins and/or developmental morphogenic proteins expressed from a genetic construct are used for ex situ treatment methods and for in planta cellular reprogramming.

The present invention relates to cultivated cucumber plants comprising modifications in their genome, whereby the modifications confer reduced susceptibility to internal fruit rot symptoms caused by Didymella bryoniae, and to methods for generating such plants, and their use.

A method for breeding a new germplasm of clubroot-resistant orange-heading Chinese cabbage includes: (1) obtaining F.sub.1 by hybridizing orange-heading Chinese cabbage as a female parent and clubroot-resistant Chinese cabbage as a male parent, obtaining F.sub.2 by selfing F.sub.1 individual plants, planting F.sub.2 populations, and extracting DNA from the individual plants of F.sub.2; (2) observing horticultural traits of F.sub.2, and performing observation and statistics of head color phenotypic traits through cutting head; (3) performing PCR amplification with DNA of F.sub.2 using a dominant orange gene marker Br530 and a clubroot-resistant marker SC2930-T/SC2930Q, and identifying a genotype of the individual plants; (4) performing a comprehensive evaluation according to the results of marker detection and the observation of horticultural traits, selecting double-site homozygous clubroot-resistant orange-heading Chinese cabbage plants, and selfing the individual plants for 2 consecutive generations; and (5) obtaining a new germplasm of clubroot-resistant orange-heading Chinese cabbage after selfing for 3 generations.

The present invention relates to a method for identifying and selecting plants resistant to a fungal disease comprising the steps of; (a) extraction of nucleic acid from a plant; (b) analysis of extracted nucleic acid for the presence of markers associated with increased fungal resistance within a single chromosome interval; and (c) selection of the plants that have these markers.

Furthermore, the invention also relates to a method for introgression into plants of fungal disease resistance alleles comprising the steps of; (a) crossing parents of plants identified by the first embodiment method with other parents that do not have this resistance; (b) select progenies possessing markers associated with increased resistance to fungal disease using the method as defined in the first achievement; and (c) backcross in one or more cycles the selected progenies with the recurrent genitor to develop new progenies.
