Genetic Variability and Yield Performance of Sorghum
The experiment was conducted using Randomized Complete Block Design with Row Column arrangement and three replications. Grain yield, phenological and other traits were recorded. The Residual Maximum Likelihood (REML) combined analysis of variance across locations showed very highly significant (P

متن کاملVariability in krill biomass links harvesting and climate warming to penguin population changes in Antarctica.
The West Antarctic Peninsula (WAP) and adjacent Scotia Sea support abundant wildlife populations, many of which were nearly extirpated by humans. This region is also among the fastest-warming areas on the planet, with 5-6 °C increases in mean winter air temperatures and associated decreases in winter sea-ice cover. These biological and physical perturbations have affected the ecosystem profound...
متن کاملUse of moored acoustic instruments to measure short-term variability in abundance of Antarctic krill
Upward-looking acoustic Doppler current profilers (ADCPs) (300 kHz) and echosounders (125 kHz) were deployed on moorings at South Georgia to measure abundance of Antarctic krill continuously over several months. Echoes from krill were identified using the theoretical difference in echo intensity at 300 and 125 kHz and scaled to krill density using target strengths appropriate for krill in the r...
متن کاملGenetic variability and differentiation of common carp (Cyprinuscarpio) in southern Caspian Sea and Aras dam
Common carp CyprinuscarpioL. is an important economic species in Caspian Sea. Genetic variability and differentiation of common carp investigated in and Gorgan rood estuary, Ramsar shoreline, Anzali wetland and Aras dam using microsatellite markers. A total of 100 specimens of adult common carp were sampled from regions. Seven pairs of microsatellites were tested on the common carp. In this stu...
