The narrow genetic base of soybean makes cultivar characterization based on morphological descriptors difficult; this characterization is mainly done for registration and protection. Correct characterization of cultivars could be achieved through molecular markers, since the frequencies of each allele in the population are known. Consequently, we developed a molecular characterization method an...

Zak ERA8 (ENHANCED RESPONSE to ABA8) (Reg. No. GP-966, PI 669443) is a unique line derived from soft white spring wheat (Triticum aestivum L.) cultivar Zak that has increased seed dormancy but after-ripens within 10 to 16 wk. The goal in developing this germplasm was to use increased seed dormancy to improve tolerance to preharvest sprouting, a problem that can cause severe economic losses. Thi...

autumn planting of sugar beet as compared to its spring cultivation demands less application of water in semi-arid region such as iran. therefore, cultivation of sugar beet in autumn is considered as a better choice to be benefited from autumn and winter precipitation and escaping from water deficit crises. in two areas of aran-o-bidgol, esfahan (ae) and izeh, khuzestan (ik), two independent ex...

Self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically and makes orchard management difficult. Therefore, breeding almond to produce self-compatible genotypes is very important. In this research identification and screening of 86 almond progenies obtained from selfing Touno after the self-pollination by PCR reaction with specific ...

Eight almond (Prunus dulcis L.) cultivars from 12 different California counties, collected during crop years 2004 to 2005 and 2005 to 2006, were extracted with petroleum ether. The extracts were subjected to GC-MS analyses to determine fatty acid composition of soluble lipids. Results indicated palmitic (C16:0), oleic (C18:1), linoleic (C18:2), and alpha-linolenic (C18:3) acid, respectively, ac...

Four ecotypes of the species Lycopersicon cheesmanii ssp. minor (Hook.) C.H. Mull. from the Galapagos Islands were compared with L. esculentum Mill cv. VF 36 with respect to salt tolerance. The L. cheesmanii ecotype that proved most salt-tolerant was selected for detailed comparison with the L. esculentum cultivar. Plants were grown in modified Hoagland solution salinized with synthetic seawate...

Samples were collected from different regions of two provinces, Markazi and Semnan, their contamination by Aspergillus flavus was examined. The results of A. flavus colony counts in different samples of almond showed that among 20 experimented samples, 11 samples were contaminated by fungus; therefore, 8 cultivars of almond, Shahroud 6, Shahroud 21, Shahroud 12, Shahroud 8, Shahroud 17, Rabie, ...

Glutinous rice (Oryza Sativa var. glutinosa) is known as waxy or sticky and it has an opaque small size grain cultivar distinct from common white rice. In outlining the equipment for processing, storage, sorting, sizing other post-harvest particular of their physical properties important. Two different local glutinous susu siding were evaluated in this study. For cultivar, average length, width...

Discrimination between disomic and tetrasomic inheritance aids in determining whether tetraploids originated by allotetraploidy or autotetraploidy, respectively. Past assessments of inheritance in tetraploids have used analyses whereby each inheritance hypothesis is tested independently. I present a Bayesian analysis that is appropriate for discriminating among several inheritance hypotheses an...
