To better understand the morphological variation for Perilla crop in different areas of China, we studied the morphological variation in 87 accessions (84 cultivated var. frutescens and three cultivated var. crispa) from high latitude (Northeast China) and middle latitude (North and Northwest China) areas of China by examining seven quantitative and 10 qualitative characters. Analysis of the mo...

OBJECTIVE This was a study of positive psychological traits in a group of rural Italians aged 90 to 101 years, and their children or other family members. DESIGN Mixed-methods quantitative (standardized rating scales) and qualitative (semi-structured interviews) study. SETTING Study participants' homes in nine villages in the Cilento region of southern Italy. PARTICIPANTS Twenty-nine nona...

Many statistical methods have been proposed in recent years to test for genetic linkage and association between genetic markers and traits of interest through unrelated nuclear families. However, most of these methods are not valid tests of association in the presence of linkage when some of the nuclear families are related. As a result, related nuclear families in large pedigrees cannot be inc...

genetic diversity in bean collection can be used in breeding program for selection of genotype with desirable agronomic traits. fifty two accessions of common bean (phaseolus vulgaris) has been evaluated for genetic diversity of agronomic traits, grain quality and determination of association between grain yield and some morphological traits at research farm of national plant gene bank of iran,...

Adherence to treatment regimens were investigated in eighty-three individuals with Chronic Kidney Disease. Personality traits of conscientiousness and agreeableness, necessity and concern medication beliefs and health locus of control were examined. This quasiexperimental, cross-sectional, correlational, quantitative and qualitative design consisted of an anonymous online survey with measures i...

Abstract: Grain yield is a complex phenomenon which results from the interaction of various contributing factors highly influenced by environmental variation. Phenotypic selection cannot directly improve the characters in heterozygous crops like maize unless dissected by genetic analysis. Gene action for various quantitative and qualitative traits was explored in a complete set of diallel invol...

Sexual selection driving display trait divergence has been suggested as a cause of rapid speciation, but there is limited supporting evidence for this from natural populations. Where speciation by sexual selection has occurred in newly diverged populations, we expect that there will be significant differences in female preferences and corresponding male display traits in the absence of substant...
