The Pvr4 resistance gene in pepper confers a complete resistance to the three pathotypes of potato virus Y (PVY) and to pepper mottle virus (PepMoV). In order to use this gene in a marker-assisted selection (MAS) program and to permit the pyramiding of several potyvirus resistance genes in the same cultivar, tightly linked amplified fragment length polymorphism (AFLP) markers were obtained by t...

Variation present in vegetables provides plentiful of opportunity for development breeding lines and hybrids. Germplasm depends on incorporation approaches such as MAGIC population, use wild relatives, genetic transformation transferring resistance gene pyramiding. These are most reliable to improve qualitative well quantitative characters. Since conventional methods time consuming, molecular t...

Anthracnose disease (Colletotrichum lindemuthianum (Sacc. et. Magn) Lams. Scrib.) is one of the most devastating diseases that constrain common bean production in Uganda. A cascading pedigree pyramiding scheme was used to develop populations evaluate effectiveness pyramided and single resistance genes (Co-42, Co-43, Co-5, Co-9) on development. Detached leaf trifoliates F4:6 genotypes were scree...

The two-spotted spider mite Tetranychus urticae is a damaging pest worldwide with a wide range of host plants and an extreme record of pesticide resistance. Recently, the complete T. urticae genome has been published and showed a proliferation of gene families associated with digestion and detoxification of plant secondary compounds which supports its polyphagous behaviour. To overcome spider m...

the crown wart disease caused by urophelyctis leproides on sugar beet is very important in the growing areas of north khuzestan influencing quantity and quality of the crop. the objectives of our research were to estimate general combining ability (gca) and specific combining ability (sca) of sugar beet lines as well as the gene action governing resistance to this disease. a randomized complete...

Insect resistant crop plants form the core component of Integrated Pest Management (IPM) due to their ability reduce losses and associated insecticide costs in addition protecting environment. In this review, various types resistance being cited, mechanisms causal factors responsible with examples were discussed. Traits resistance, genetics inheritance patterns listed. Several sources including...

We develop a model of asset trading with financial leverage in an economy with a continuum of investors. The investors are assumed to have diverse and rational beliefs in the sense of being compatible with observed data. We show that a reduction in the margin requirement may cause the stock price to rise in the current period because it increases the demand of optimistic investors through a “le...
