Urochloa ruziziensis; diploidy; tetraploidy; meiosis; germplasm; chromosome aberrations; chromosome segregation; chromosome pairing
Abstract:
... Sexuality is correlated with diploidy and apomixis with polyploidy in the Brachiaria genus. Brachiaria ruziziensis is a key species in Brachiaria breeding due to its obligate sexuality and intrinsic agronomic qualities. Interspecific crosses in the genus became feasible only when a few diploid accessions of B. ruziziensis were artificially tetraploidized and remained sexual. Hybridization has been ...

Abstract:
... Breeding for organic agriculture (BFOA) is a strategy for a commercial breeding company based on the exploitation of the frequently observed high correlation for many traits between conventional, low input (LI) and organic agriculture (ORG). Indirect selection under LI can be useful to roughly divide the germplasm into the genotypes better adapted to high input and those better adapted to LI or OR ...

Abstract:
... Phytophthora sojae, an important yield limiting pathogen of soybean, causes seed, seedling, root, and stem rots. Losses caused by P. sojae can be controlled by both major gene and partial resistance. Early maturity group (MG) soybeans are an increasingly important crop in northwestern Minnesota and eastern North Dakota. Early MG plant introductions (PIs) from the USDA Soybean Germplasm Collection ...

Abstract:
... We applied Bayesian population assignment methods to assess the trueness to type of four populations of the coconut cultivar Panama Tall (PNT) located in Jamaica and found that two of them presented a high percentage of off-types, while genetic contamination was low in the two others. The PNT is the pollen parent of the MAYPAN hybrid, which used to be planted in Jamaica to control an epidemic dise ...

Abstract:
... Besides phenotypic data from field trials and molecular data from lab experiments, modern plant breeding programs generate a wide variety of data, for instance pedigree, randomization, geostatistical or climate data. Due to the lack of an integrated database system, breeders generally exploit only part of these data for selection decisions or retrieve only part of the information present in the da ...

Abstract:
... A cross was made between a unique highly branched, early flowering line, U. S. Department of Agriculture (USDA) 846-1 (P₁; 7 to 11 lateral branches), and 'Topmark' (P₂; 2 to 4 lateral branches), a U.S. Western Shipping melon, to produce an array of 119 F₃ families. Subsequently, a genetic analysis was conducted at Arlington and Hancock, Wisconsin in 2001 to evaluate the segregating progeny for fac ...

Abstract:
... Trigonobalanus doichangensis is recognized as a rare and endangered plant of China. The morphological and physiological traits of fruits were investigated in one population over 2 years (2006-2007) and in four populations during 2007 in order to facilitate ex-situ conservation and eventual reforestation through planting of propagules. The results indicated that morphological traits including fruit ...
