Tree survival, early fruit production, vegetative growth and alternate bearing were examined in six different olive cultivars (Barnea, Biancolilla, Coratina, Empeltre, Koroneiki and Leccino) under intensive agronomic conditions in southern Atacama Desert, in the Coquimbo Region of Chile. The cultivars were evaluated over four successive years and had a high survival rate (93%) confi rming their...

to determine the effect of seed size of sugar beet cultivars on germination and seedling vigor, a study was conducted as a 4×6 factorial experiment based on completely randomized design with 4 replications at seed and plant certification and registration institute, karaj in 2013. the treatments were toucan, dorotea, rasta, sharif, pars, and torbat cultivars and four seed width sizes including 2...

Peanut or groundnut (Arachis hypogaea L.) sown in early spring often has poor seed germination and seedling development. The influence of soil temperature on seedling emergence and early growth of six peanut cultivars (Florida MDR98, Southern Runner, Georgia Green, SunOleic 97R, Florunner and C-99R) was studied in natural field soil profiles in temperature-gradient greenhouses. We evaluated the...

The genetic diversity among 56 almond (Prunus dulcis) genotypes was analysed using 35 microsatellite markers and 14 morphological traits. Analysis of morphological traits revealed a wide range of variation among the studied genotypes. Out of 35 simple sequence repeats (SSRs) markers, 25 were polymorphic, producing 215 alleles that varied from 2 to 16 with an average of 8.76 alleles per locus. R...

The aim of the study is to determine genetic diversity and relationships among olive cultivars native to Croatia and Turkey. A total of twenty olive (Olea europaea L.) cultivars including fourteen from Croatia and six common cultivars from Turkey were analyzed for genetic diversity and relationships by using six microsatellite markers (DCA05, DCA09, DCA18, GAPU71B, GAPU101, UDO43). The number o...

Red rod is an economically important disease of sugarcane caused by the fungus Colletotrichum falcatum. We used a simple sequence repeat (SSR)-based marker system to identify and analyze genetic relationships of red rot resistant and susceptible sugarcane cultivars grown in Pakistan. Twenty-one highly polymorphic SSR markers were used for DNA fingerprinting and genetic diversity analysis o...

The main objective of this study was to verify the association between the coefficient of parentage estimates and multivariate techniques which were used as measures of genetic diversity in cultivars. Thirty cotton cultivars were used for this purpose among which genetic diversity was estimated by means of the parentage coefficient (CP) and also through multivariate techniques employing microsa...

The objective of this study was to evaluate the stenting (grafted cutting) propagation of commercial pomegranate cultivars as scions on drought tolerant genotypes as rootstocks. The effect of drought stress on nine pomegranate rootstocks was analyzed. Cultivars including ‘Daneshgah 13’, ‘Daneshgah 32’ and ‘Daneshgah 8’ that were used as rootstocks showed the maximum drought tolerance among the ...

the influence of leaf pubescence of three wheat cultivars (pishtaz, ghuds and falat) on preference and biological parameters of sipha maydis (passerini) was investigated under greenhouse conditions (25 ± 2 °c, 70 ± 10% rh and 14: 10 h (l: d) photoperiod). the results showed that pishtaz had a greater density of trichomes compared to the other cultivars. in the preference test with whole plant, ...

the sugar beet weevil, lixus incanescens boh., is an important insect pest of sugar beet, beta vulgaris l., in razavi khorasan province. in this research, population densities of the sugar beet weevil eggs and larvae were evaluated on plants of six sugar beet cultivars including ardabili, aras, persia, flores, laetitia and rosire in an experimental field in 2011 and 2012. also, the percentage o...
