This study was conducted to evaluate the response of 18 rice (Oryza sativa L.) genotypes to callus induction and plant regeneration from immature embryo culture, using three media (MS, LS and N6). To evaluate callus induction rate, the following criteria were used: callus diameter, callus fresh weight and callus dry weight. Percentage of callus water content was also measured. After transferrin...
to study the tolerance of genotypes under terminal drought stress, 20 promising winter and facultative bread wheat genotypes were evaluated at karadj, ardebil, arak and hamedan agricultural research stations during 2001-02 cropping season. the experimental design in all the locations was randomized complete block of three replications. grain yield (yld), harvest index (hi), grain number per spi...

The overall rate of self-fertilization can be viewed as the sum of two distinct processes: 1) self-pollination of all ovules in a flower (whole-flower self-pollination); and 2) self-pollination of some of the ovules in a flower, occurring together with outcrossing of the remaining ovules (part-flower self-pollination). In some situations these processes may be equated with different modes of se...
in order to study the genetic diversity among some male pistachio genotypes,16 male pistachio genotypes and 8 female pistachio cultivars were selected from iranian pistachio research institute (ipri). 12 rapd primers were used which totally produced 65 bands that among them 48 bands were polymorphic and 17 bands were monomorphic. cluster analysis based on similarity matrix and jaccard similarit...
BACKGROUND Pollination has a great effect on the yield of fruit trees. Blow flies are considered as an effective pollinator compared to hand pollination in fruit orchards. Therefore, this study was designed to evaluate the effect of different pollination methods in mango orchards. METHODOLOGY The impact of pollination on quantity and quality of mango yield by blow flies was estimated by using...
The combining ability analysis using Line × Tester model was conducted in chickpea to know the general and specific combining ability of the distingushing parents and their crosses, respectively and to select best material for further breeding programme and generation advanceme- nt. Two genetically diverse testers viz., JAKI-9218 and ICCV-2 as females and 8 males viz., HC-5, ICC-506, PKV Harita...
Drought stress is one of the most important abiotic factors which adversely affects growth, metabolism and yield of crops worldwide. The goal of the research was identify drought tolerate canola genotypes using the different drought tolerance indices. The experiment was conducted as split plot based on randomized complete block design with three replications at the experimental farm of agricult...
the present research was conducted with the purpose of studying self and cross-compatibility in some commercial cultivars of peach through field and microscopic studies in order to increase the quantity and quality traits of the product. the study was carried out in years 2010 and 2011. in a first experiment, the pollen germination of 10 cultivars of peach was studied in culture medium. the res...
To study the responses of seven rice genotypes (Khazar, SA13, Deylam, Sange Joe, Sepidrud, 831 and T5) to different levels of irrigation water salinity, and determining grain yield based on tolerance indices, a CRD based factorial pot experiment with five levels of irrigation water salinity (1, 2, 4, 6 and 8 dSm-1) and three replications was carried out at Rice Research Institute of Iran in 201...
