Open AccessGenome resources for three modern cotton lines guide future breeding efforts
Cotton (Gossypium hirsutum L.) is the key renewable fibre crop worldwide, yet its yield and fibre quality show high variability due to genotype-specific traits and complex interactions among cultivars, management...

Comparative transmission genetics of introgressed chromatin in reciprocal advanced backcross populations in Gossypium (cotton) polyploids
Introgression is a potential source of valuable genetic variation and interspecific introgression lines are important resources for plant breeders to access novel alleles. Experimental advanced-generation back...

Cross-taxon application of sugarcane EST-SSR to genetic diversity analysis of bermudagrass (Cynodon spp.)
Bermudagrass lags in genomic and molecular breeding resources, particularly regarding a critical mass of robust, reproducible, and highly polymorphic molecular markers like simple sequence repeats (SSR). Here,...

Comparative genetic variation of fiber quality traits in reciprocal advanced backcross populations
Introgressive breeding to introduce both obvious variation into a gene pool, and to unmask cryptic variation masked by close linkage or epistatic interactions, has repeatedly been attempted to improve fiber tr...

SSR-enriched genetic linkage maps of bermudagrass (Cynodon dactylon × transvaalensis), and their comparison with allied plant genomes
We report SSR-enriched genetic maps of bermudagrass that: (1) reveal partial residual polysomic inheritance in the tetraploid species, and (2) provide insights into the evolution of ch...

Targeted identification of association between cotton fiber quality traits and microsatellite markers
Primitive and exotic accessions of cotton are potential sources of favorable alleles for genetic improvement, enriching diversity in the genetically constricted gene pool of elite cultivars. Three exotic acces...

Open AccessComparative map** in intraspecific populations uncovers a high degree of macrosynteny between A- and B-genome diploid species of peanut
Cultivated peanut or groundnut (Arachis hypogaea L.) is an important oilseed crop with an allotetraploid genome (AABB, 2n = 4x = 40). Both the low level of genetic variation within the cultivated gene pool and it...

Open AccessA high-density genetic map of Arachis duranensis, a diploid ancestor of cultivated peanut
Cultivated peanut (Arachis hypogaea) is an allotetraploid species whose ancestral genomes are most likely derived from the A-genome species, A. duranensis, and the B-genome species, A. ipaensis. The very recent (...

Recombination is suppressed in an alien introgression in peanut harboring Rma, a dominant root-knot nematode resistance gene
Rma, a dominant root-knot nematode resistance gene introduced into tetraploid peanut (Arachis hypogaea) from a synthetic allotetraploid donor (TxAG-6), has been widely deployed in modern cultivars. The genomic lo...
