Previously we have described a mutant Hfr strain in which incompatibility between the integrated F factor and an autonomous F-prime (F') factor was abolished. The mutation (inc) was located in the integrated F factor. F-prime factors isolated from the mutant Hfr strain have the same incompatibility behavior as those isolated from normal Hfr strains. Reintegration of these F' factors into the ch...

Planning the artificial pollination of agricultural crops requires knowledge of the floral biology and reproductive system of the crop in question. Many studies have shown that rapeseed (Brassica napus Linnaeus) is self-compatible and self-pollinated, but its productivity may be increased by insect visitation. In the present study, the floral biology and the response of productivity to insect v...

BACKGROUND AND OBJECTIVE: Hyperbilirubinemia is one of the most common problems during the neonatal period. Despite the severe complications of jaundice, no reliable data is available regarding the prevalence of acute and chronic complications of jaundice and the predisposing factors in our community. Therefore, this study aimed to determine the complications of neonatal jaundice and the predis...

Perennial ryegrass is an important turf and forage grass in temperate regions worldwide. Limited genetic gains have been made with current breeding strategies compared other crops, such as rice maize, which benefit from Filial 1 (F1) hybrid breeding. One of the largest constraints on self-incompatibility preventing inbreeding, homozygous parental lines are required to develop hybrids maximal vi...

Fusarium head blight (FHB) is a serious disease of wheat and barley that is best controlled by host resistance. In KSU Extension publications, the reaction to FHB for winter wheat cultivars is reported to producers using a 1-9 scale where 1-3 = resistant, 4-6 = intermediate, and 7-9 = susceptible. This research sought to determine how many location-years are needed to accurately determine the r...

Intake of phytosterols (and -stanols) has been shown to decrease the level of low-density lipoprotein cholesterol and thus protect against development of cardiovascular diseases. Therefore, studies on the cultivar and year-to-year variation in phytosterol content in rye grains have been performed. The phytosterol content and composition of different rye cultivars, grown under identical conditio...

Plant variety and cultivar identification is one of the most important aspects in agricultural systems. The large number of varieties or landraces among crop plants has made it difficult to identify and characterize varieties solely on the basis of morphological characters because they are non stable and originate due to environmental and climatic conditions, and therefore phenotypic plasticity...
