Diallel analysis of scald and net blotch resistance in barley (Hordeum vulgare L.)

Scald and net blotch are major foliar diseases of barley causing high yield losses worldwide including Ethiopia. Development of varieties with double resistance is an effective approach of managing both diseases. However, the genetic background of the barley parents was not studied for future resistance breeding. Thus, the objective of the study was to assess genotype performances against scald and net blotch,...

Extended distribution of testate amoebae (Protozoa: Rhizopoda) to Indian fauna from Sangla Valley, Himachal Pradesh, India

Testate amoebae are a group of free-living heterotrophic protists that have an organic shell or test and play a very good role as bioindicators in the ecological monitoring of environment. Inspite of the importance the percentage contribution of free living protozoans recorded from the Himalayan landscape is only about 12% of the total free living protozoans of India. This portrays a meagre diversity of species from...

Democratization and nation-building in Nigeria, from 1914 to 2004: An appraisal

Nigeria came into being in 1914 following the British colonial authority's amalgamation of the Northern and Southern protectorates during which various ethnicities were living independently of each other. However, the activities leading up to the 1914 amalgamation predates this date. It would therefore not be out of place to say that the most enduring legacy of British colonialism is the geo-political entity known...
