Genetic Variability for Morphological Traits in F3:4 Brassica Populations
Genetic variability is an indicator for a plant breeder to proceed further. Six F3:4 derived inter-specific Brassica populations along with three checks were evaluated for genetic variability for agronomic characters at NWFP Agricultural University, during 20052006. Highly significant (P < 0.05) genetic variations were recorded for plant height. Maximum number of pods main receme (94) was obser...
متن کاملEffect of skin application of sun-flower oil on serum triglyceride and cholesterol in premature newborns
Introduction: Total parental nutrition is essential in premature newborns who are unable to have oral feeding. Intra venous Lipid (Intra lipid) is used to preparing essential fatty acids and a compact source of energy. We aimed in this study to investigate the effect of skin intra lipid. Methods: Premature newborns, who were through admitted in NICU unable to feed orally, were investigated in...
متن کاملSun exposure measurements in populations.
Measuring ultraviolet (UV) exposure in human populations is a complex task. The dominant source of ultraviolet radiation for humans is sunlight, which is always a mix of both ultraviolet A (UVA, usually 320– 400 nm) and ultraviolet B (UVB, 320–280 nm). Ultraviolet C ( 280 nm) is filtered by the atmosphere and does not reach the earth’s surface. Researchers cannot separate the individual effects...
متن کاملMEIOTIC STUDIES OF SOME AVENA SPECIES AND POPULATIONS IN IRAN
Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...
متن کاملPHENETIC STUDIES IN AVENA SPECIES AND POPULATIONS OF IRAN
A multivariate statistical analysis was performed on morphological characters of sixty-one populations of Avena eriantha Dur. A. clauda Dur., A. barbata Pott ex Link., A. wiestii Steud., A. fatua L., A. sterilis ssp. ludoviciana L. and A. sativa L. Factor analysis revealed that intraspecific morphological variations are due to quantitative characters. Interspecific as well as intersectional rel...
