Abstract
In order to evaluation of value for cultivation and use of seven new spring rapeseed cultivars (Foruzan, Mahtab, Zaman, Moj, Dalgan, Z10B, SAN14) and seven commercial cultivars of Rapeseed (Sari Gol, RGS003, Hayola 420, Hayola 308, Hayola 401, Hayola 50, and Zafar) as a Reference collection were carried ...

In order to evaluation of value for cultivation and use of seven new spring rapeseed cultivars (Foruzan, Mahtab, Zaman, Moj, Dalgan, Z10B, SAN14) and seven commercial cultivars of Rapeseed (Sari Gol, RGS003, Hayola 420, Hayola 308, Hayola 401, Hayola 50, and Zafar) as a Reference collection were carried out in a randomized complete block design with three replications at the Seed and Plant Certification and Registration Institute-Karaj in 2015-2016. The measured agronomic traits were including, 1000-seed weight, number of silique per plant, number of seeds per silique, oil percent, Maturity date and grain yield were determined according to the UPOV instruction. The results show that, hybrid cultivars such as Hyola 50 and Hyola 401 have the highest yield. Considering the superiority of Mahtab, Zaman and Dalgan cultivars in terms of yield and having crop value compared to other cultivars, these varieties can be introduced as new cultivars for registration and commercialization. Keywords: Rapeseed, Reference collection, Spring varieties

High temperature during seed set and seed filling can reduce yield and seed quality. In order to evaluate the effect of high temperature during planting date and also plant density on soybean seed quality, an experiment was conducted at two locations, namely, Seed and Plant Certification and Registration Institute in Karaj and Agricultural and Natural Resource Center of Moghan, in 2013. The studied factors were included planting date (5th of May, 5th of June and 5th of July), plant density (300, 400 and 500 thousand plant/ha) and soybean varieties (Williams and L17) were sown in the rate of 40 plants per m-2 at 5th May, 5th June and 5th July. The experiment was conducted as a factorial based on a randomized complete block design (RCBD) with three replications. The results of standard germination test showed that in Moghan area, the highest normal seedling percentage (92.1%) was obtained at fifth of June and in Karaj area, it (96.2%) was gained at fifth of July. In addition, it was noticed that cv. L17 in Moghan and cv. Williams in Karaj had the highest normal seedling percentage. The results of accelerated aging test was cleared that the normal seedling percentage in karaj was more than Moghan area and it showed that the quality of seed that were produced in Karaj was better than Moghan area. There was no significant difference between areas in 300 and 400 thousand of plant/ha and in these both density, the result of Karaj was better than Moghan area, but there was significant difference between normal seedling percentage after accelerated aging test in Karaj (77.6%) and Moghan (58%) in 500 thousand plant/ha. The highest seedling vigor index (11.75) was obtained in 400 thousand plants/ha at fifth of July in Karaj area and the lowest rate of it (5.41) was observed in 300 thousand plants/ha at fifth of June in Karaj area.

This study was carried out to investigate the effects of different treatments of priming on seedlings traits and seed yield of dryland wheat in labratory and field condition with three replications at the Research Station of Islamic Azad University, Arak Branch, in 2014. The experimental treatments in labratory were control, seed priming with distillate water and priming with rates of 1, 2 and 3m/L Se conducted in a completely randomized design. In field condition was also used mentiend treatments along with foliar application in a randomized complete block design. The result showed that the minimum mean germination time was 2.62 day in priming with 1m/L Se. Seed priming with distillate water and priming with 1, 2 and 3m/L Se increased seedling length by 28.5, 54.4, 49.1 and 48.5 % , respectively, as compared with control. Seed priming with 3m/L Se increased seedling vigor length index by 1.6 times as compared with control. Seed priming with 3m/L Se increased the plumule dry weight and root dry weight by 44.4 and 46.5% , respectively, as compared with control. Seed priming with 1 m/L Se increased the chlorophyll b by 19.3 as compared with control. The result showed that seed priming with 1 and 2 m/L Se along with foliar application of Se and priming with distillate water along with foliar application of Se increased seed yield by 16.7, 19 and 17.9%, respectively, as compared with control. General results of this trail showed that seed priming with low selenium along with selenium spray under dryland condition, optimum yield of wheat can be achieved.
