Genotypic variation is useful to breeders when selecting genotypes to improve particular traits. Inorder to study of genetic diversity 20 genotypes of Hordeum murynum studied in the form of randomized complete block design the experimental field of islamic azad university shahre rey branch with 3 replication in the year 2012. Notes traits was conducted including days to heading, days t...

This study aimed to investigate the floral biology and pollination requirements of sesame (Sesamum indicum L.), cultivar CNPA G2. The study was carried out at Barbalha, State of Ceará, and consisted of two phases: floral biology and pollination requirements. Flowers were observed as for time of anthesis, lifespan and stigma receptivity, and were applied the following pollination treatments: ope...

a study was conducted to investigate the genetic variance components and the combinig ability of sunflowers lines at the seed and plant improvement institute, karaj, iran in 2006. a total of 41 genotypes including 2 cms, 13 restorer and their 26 corresponding hybrids were evaluated in a line × tester approach. the analysis of variance indicated that significant differences existed among genotyp...

We studied the relative role of inflorescence traits, flowering synchrony, and pollination context for infructescence and fruit initiation in two Spanish populations of Arum italicum, a species in which inflorescences are the pollination unit. In this species, a specialized inflorescence organ, the appendix, is important for pollinator attraction. However, the short floral longevity and the pro...

to determine the effects of different pollen types and suitable pollination time in medjhol date palm, an experiment was carried out with three pollen cultivars: ghaname, vardy and samesmave and two pollination times (1-3 days before or after spathe opening) during 2010-2011 in date palm and tropical fruit research institute in ahwaz. the results showed that the vardy pollen had the most signif...

Castor is one of neglected African oil crops with little research attention in Nigeria. In the present research, eighty-six castor genotypes were evaluated at three locations in Niger State, Nigeria. The aim was to estimate the extent of genetic variability and also to examine the associations among the seed yield and its components. The treatments were laid out in an Alpha Lattice Design with ...

in order to evaluate some morphological traits of durum wheat genotypes, 18 elite lines selected from advanced regional durum wheat yield trials. these materials along, with two checks dena (durum wheat) and parsi (bread wheat) were examined using rcb design with three replications at isfahan research station in two consecutive cropping season. during the cropping season some trials such as the...

the periwinkle with the scientific name of catharanthus roseus is one of the most important ornamental plants of the apocynaceae family. in order to evaluate the effect of different waters on the amount of the nutrient elements in soil and aerial parts of catharanthus roseus, a factorial experiment based on completely randomized design was conducted in 3 replications. experimental treatments we...
