MANY ENDEMIC DISEASES are controlled through the cropping of resistant sugarcane varieties. Routine resistance screening trials for a range of diseases are a core activity of BSES. Central to this is the appropriate statistical analysis of data from these trials. This is important since potentially high-yielding varieties could be discarded from the breeding program if they are incorrectly rate...

this research in order to identify and introduction of  cotton  suitable cultivar  or cultivars for the double cropping of after wheat and canola harvesting  was carried out in the northern region of ardebil province. in this study, eight  varieties  of    imported cotton germplasm resources in recent years were chosen   and   with the iran's cultivars included  mehr  and varamin  were eva...

We study higher order determinantal varieties obtained by considering generic m × n (m ≤ n) matrices over rings of the form F [t]/(t k), and for some fixed r, setting the coefficients of powers of t of all r × r minors to zero. These varieties can be interpreted as generalized tangent bundles over the classical deter-minantal varieties; a special case of these varieties first appeared in a prob...

Recent trade data exhibit the following four empirical regularities: (i) countries import only a small fraction of all traded varieties (ii) per capita income and the number of imported varieties correlate positively (iii) per capita income and trade shares correlate positively and, finally, (iv) world trade shares have increased substantially. The present paper argues that standard theories fa...

Twenty-one hop varieties from Europe and the United States were successfully identified by DNA analysis, based on single nucleotide polymorphisms (SNPs; including insertion/ deletion sequences) as identification markers. Several dozen megabases of transcriptome sequencing data were obtained by next-generation sequencing of samples from three hop varieties and compared to search for the regions ...

Fifty rice varieties collected under different categories from various sources were grown at the BRRI field during the 2001 transplant aman season ( July–November). Precautions were taken during harvest and processing to prevent mineral contamination. All samples were hand-pounded before being analyzed for iron and zinc content. The iron and zinc content varied considerably within the different...

The paper presents smallholder farmers' perceptions on attributes of bread wheat varietiesbased on primary data collected from 524 households in four major wheat growing areas ofEthiopia. The results indicated high value of attainment indices for improved varieties comparedto landraces, which shows how the demanded attributes are embodied more in improved ones.Grain yield and yellow and stem ru...

We investigate unibranched singularities of dual varieties of evendimensional smooth projective varieties in characteristic 2.
