in order to study the response of new sugar beet hybrids and cultivars to curly top disease in the field conditions, an experiment was carried out in a randomized complete block design with four replications and sixteen treatments in 2007 in fasa. each plot included a hybrid or cultivar planted in three rows with eight meter length and 50cm between- row spacing. after weeding and first thinning...

in order to select of the best nectarine cultivars in meshkinshahr environmental condition, 11 cultivars of nectarines (including: independence, star redgold, stark sunglow, sanking, quata, shabrang e karaj, germez-e-paeez-e-mashad and 4 new imported cultivars including: winberger, vega, orion and gioia) were grafted on misory peach rootstock. cultivars were planted in randomized complete block...

Discerning the genetic diversity of any crop species provides insight into the strength of an applied breeding program and directs future breeding strategies aimed at long-term genetic gain and minimized genetic vulnerability. The number and abundance of ancestral parents present in the pedigree of crop cultivars can provide an average estimation of the depth of the genetic base of the overall ...

Article history: Received 2 December 2009 Received in revised form 18 October 2010 Accepted 23 December 2010 The study was conducted to determine chemical composition and standardised ileal digestibilities (SID) of crude protein (CP) and amino acids (AA) in currently available grain legume cultivars for growing pigs. Three consecutive experiments were conducted with six barrows each, fitted wit...

The pink hibiscus mealybug, Maconellicoccus hirsutus (Green), is a highly polyphagous pest that invaded southern Florida in 2002 and is now widely established throughout most of the state. Although Hibiscus rosa-sinensis L. is a preferred and economically important host of M. hirsutus, the susceptibility and expression of feeding symptoms by different cultivars have not been evaluated. Cultivar...

Analysis of DNA polymorphisms allows for the genetic identification and precise discrimination of species with a narrow genetic base such as common bean. The primary objectives of the present study were to molecularly characterize commercial common bean varieties developed at various research institutions using microsatellite markers and to determine the degree of genetic diversity among the be...
