Genetic diversity of 20 sugarcane accessions in Pakistan was studied using 21 random amplified polymorphic DNA markers. The mean genetic distance between the cultivars was 39.03%, demonstrating that a large part of the genome is similar among the accessions. This probably arises from a lack of parental diversity, with few clones, which are themselves related, contributing to the parentage of th...

for investigation quantitative and qualitative properties of different lines and cultivars of rapeseed, 19 selected lines from advanced inbreeding progenies, and zarfam variety (as check), totally 20 lines and varieties, were evaluated in a randomized complete block design with three replications at the experimental field of seed and plant improvement institute in karaj, during 2005-6. morpholo...

in order to induce of genetic variation and selection of genotypes with desirable traits, seeds of three varieties of rapeseed sarigol (pf), rgs003 and zarfam were treated with different doses of gamma ray 500, 700 and 900 gy. to confirm the stability of the induced genetic traits, 66 mutant lines from m4 generation were studied in a randomized complete block design with three replications. twe...

the present study was carried out with the objective of validating linked ssr markers to rf genes and adopting marker assisted selection (mas) for restorer/non-restorer line detection in wild abortive (wa) type of cytoplasmic male sterility (cms). twelve ssr markers reported to be linked to rf genes were analyzed in the mapping population of nedaa/pajouhesh. among these, three markers, namely, ...

In this paper we study the partially ordered set Q of cells in Rietsch’s [20] cell decomposition of the totally nonnegative part of an arbitrary flag variety P ≥0 . Our goal is to understand the geometry of P ≥0 : Lusztig [13] has proved that this space is contractible, but it is unknown whether the closure of each cell is contractible, and whether P ≥0 is homeomorphic to a ball. The order comp...

We describe explicitly the admissible families of minors for the totally nonnegative cells of real matrices, that is, the families of minors that produce nonempty cells in the cell decompositions of spaces of totally nonnegative matrices introduced by A. Postnikov. In order to do this, we relate the totally nonnegative cells to torus orbits of symplectic leaves of the Poisson varieties of compl...
