Inheritance of Barley yellow dwarf virus resistance in maize

With increasing winter temperatures due to climate change, Barley yellow dwarf virus (BYDV) is expected to become a prominent problem also in maize cultivation. Breeding for resistance is the best alternative to control the disease and break the transmission cycle of the virus. The objectives of our study were to (I) determine phenotypic and genotypic variation in five segregating populations o...

A Genetic Study of Linkage and Inheritance in Barley

Ribosomal DNA spacer-length polymorphisms in barley: mendelian inheritance, chromosomal location, and population dynamics.

Spacer-length (sl) variation in ribosomal RNA gene clusters (rDNA) was surveyed in 502 individual barley plants, including samples from 50 accessions of cultivated barley, 25 accessions of its wild ancestor, and five generations of composite cross II (CCII), an experimental population of barley. In total, 17 rDNA sl phenotypes, made up of 15 different rDNA sl variants, were observed. The 15 rDN...

Exclusion of male mitochondria and plastids during syngamy in barley as a basis for maternal inheritance.

It is known from genetic analyses that maternal inheritance of cytoplasmic organelles is the rule among plants and animals. Although recognized as one of several possible mechanisms for strictly maternal cytoplasmic inheritance, exclusion of sperm cytoplasm at the time of gametic fusion has remained poorly documented for the flowering plants. In the present investigation, enucleated, cytoplasmi...

Inheritance of Russian Wheat Aphid Resistance in Spring Barley Germplasm Line STARS-9577B

A damage rating scale for wheat and barley seedlings was developed by Webster et al. (1991) based on visual The Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), rating of leaf chlorosis, leaf streaking, and leaf spotting. has become a major pest of barley (Hordeum vulgare L.) in the This visual rating was on a scale of 1 to 9 (1 no western USA.
