Grain length in rice plays an important role in determining rice appearance, milling, cooking and eating quality. In this study, the genetic basis of grain length was dissected into six main-effect quantitative trait loci (QTLs) and twelve pairs of epistatic QTLs. The stability of these QTLs was evaluated in four environments using an F7 recombinant inbred(More)
The effects of the monoterpenes of 3-carene, 1,8-cineole, beta-pinene, terpinene and terpinolene on the repellent, contact toxicity of Tribolium castaneum adults and sustaining fumigant toxicity of Sitophilus zeamaise adults were examined. Monoterpene of 1,8-cineole in 20 microL mL(-1) and beta-pinene in 20 microL mL(-1) exhibited the highest percentage(More)
The angoumois grain moth, Sitotroga cerealella, is one of the most serious stored-grain pests worldwide. Control of this moth may be achieved by interfering with olfactory pathways to disrupt male-female communication with sex pheromones, using plant volatiles like garlic or its active substances. Here, three odorant-binding protein (OBP) genes [namely Si.(More)
The oriental army worm Mythimna separata (Lepidoptera: Noctuidae) is a migratory pest in Eastern Asia and China. Seasonal high temperatures in Southern China and low temperatures in Northern China are pressures favouring the annual migration of this species, while cold tolerance determines the northern limit of its overwintering range. A number of(More)
We found that the fragility hip and vertebral fractures caused excess mortality rates in this Chinese female population, which was unexpectedly lower than those in western countries and other Asian countries. This was the first nationwide survey relating to post-fracture outcomes conducted among Chinese population in Mainland China. This study aimed to(More)
OBJECTIVE To study the changes and significance of oblique occipital frontal diameter (OFD) and superior inferior diameter (SID) of the hepatic left lobulus in different stages of hepatic fibrosis, and to evaluate the value of corresponding serological examination in the non-invasive diagnosis to hepatic fibrosis and cirrhosis. METHODS Seventy-two(More)
Temperate insects have evolved diapause, a period of programmed developmental arrest during specific life stages, to survive unfavourable conditions. During the diapause preparation phase (DPP), diapause-destined individuals generally store large amounts of fat by regulating nutrition distribution for the energy requirement during diapause maintenance and(More)
One indica variety, Zhefu 802, was studied for its inheritance of blast resistance by inoculation of two strains Ken54-04 and 95-t2. The B1F1 and F2 populations from cross of Zhefu 802(R) x Lijiangxintuanheigu (S) and related parents were inoculated by spray inoculation method with the two above mentioned strains to determine R:S ratio of segregating(More)
