Abstract:: ... Productivity of nonlegume crops depends partly on nitrate uptake and reduction. To study the nitrate assimilation pathway of plants, the herbicide chlorate has been exploited as an analog of nitrate. Marked variations in visible leaf chlorosis among 15 soft red winter wheat (Triticum aestivum L.) seedlings exposed to 120 μM chlorate were reported by others. From their study, we selected three chlo ...

Abstract:: ... Russian wheat aphid (RWA) (Diuraphis noxia Kurdjumov) infestations of barley (Hordeum vulgare L.) cause chlorotic leaf spotting and streaking and prevent unrolling of leaves, which traps spikes and reduces grain yield. Resistant accessions identified in the USDA-ARS National Small Grains Collection (NSGC) were used to develop adapted, resistant germplasm and cultivars. This study identified loci a ...

Abstract:: ... The USDA-ARS breeding program has identified a recessively-controlled genetic variant in highbush blueberry (V. corymbosum L.) that results in parthenocarpic fruit development. Current studies are underway to refine our understanding of this variant, and to move this trait into desirable and useful genetic backgrounds. In rabbiteye blueberry (V. ashei Reade), a species with critical cross-pollinat ...

Abstract:: ... Citrus germplasm is conserved in genebanks at sites around the world to provide genetic resources for breeding and research programs. The value of genebank collections is particularly evident as diseases and climate change threaten citrus production areas. We provide historical, inventory, and maintenance information about national citrus collections in Russia and in the United States. The Russian ...

Abstract:: ... The development of inexpensive, whole‐genome profiling enables a transition to allele‐based breeding using genomic prediction models. These models consider alleles shared between lines to predict phenotypes and select new lines based on estimated breeding values. This approach can leverage highly unbalanced datasets that are common to breeding programs. The Southern Regional Performance Nursery (S ...

Abstract:: ... Cotton breeders have focused mainly on selecting for high yield and early maturity under the impact of the boll weevil (Anthonomus grandis Boh.) in the last century. Selection for high fiber quality was once a less important objective in cotton breeding. With the transition of the U.S. cotton industry from a domestic consumer to a major exporter of raw fibers into the global market and the technol ...
