in order to transfer rhizomania resistance genes to improved sugar beet lines, crosses were made between 11 commercial resistant varieties and two improved inbred o-type lines of sugar beet (231 and 261) at agricultural research center of khorasan razavi   and jam sugar factory in 2007. o-types carried self fertile (sf) genes and contained male sterile (ms) genotypes. commercial varieties were ...

Let X1, . . . , Xm denote smooth projective curves of genus gi ≥ 2 over an algebraically closed field of characteristic 0 and let n denote any integer at least equal to 1 + max i=1 gi. We show that the product JX1 × · · · × JXm of the corresponding Jacobian varieties admits the structure of a Prym-Tyurin variety of exponent n. This exponent is considerably smaller than the exponent of the struc...

Some studies have suggested that the immunogenicity of oats depends on the cultivar. RP-HPLC has been proposed as a useful technique to select varieties of oats with reduced immunogenicity. The aim of this study was to identify both the avenin protein patterns associated with low gluten content and the available variability for the development of new non-toxic oat cultivars. The peaks of alcoho...

By implementing jet differential techniques in non-archimedean geometry, we obtain a big Picard type extension theorem, which generalizes previous result of Cherry and Ru. As applications, establish two hyperbolicity-related results. Firstly, prove Ax-Lindemann theorem for totally degenerate abelian varieties. Secondly, show the pseudo-Borel hyperbolicity subvarieties general

BACKGROUND Synthetic hexaploid wheats are artificially reconstituted hexaploid wheats that possess high genetic variation which could be utilized for the development of new improved wheat varieties. One such group of synthetic wheats is called the Elite-II set of synthetic wheats that are derived from crossing durum wheat with different Aegilops tauschii wheats. MATERIALS AND METHODS In the c...

For any given Salem number, we construct an automorphism on a simple abelian variety whose first dynamical degree is the square of number. Our construction works for both varieties with totally indefinite quaternion multiplication and second kind. We then give complete classification sequences dimension at most four obtain ergodic result pullbacks forms.

in order to investigate the effect of seed rate on seed yield and yield components of three rapeseed varieties, a split- plot experiment was conducted in randomized complete block design with four replicates during 2008-2009 at baykola agricultural research station, neka, mazandaran province. in this experiment four seed rates (5, 7, 9 and 11 kg.ha-1) as main plots, three rapeseed cultivars (hy...

We prove that families of Prym varieties abelian Galois covers P1 in Ag do not give rise to high dimensional Shimura subvareties. This contributes the classification such totally geodesic subvarieties locus and extends results E. Colombo et al. which deal with 1-parameter families. Our method is based on analyzing Monodromy family.
