Is14131 and IS14257 strains and the corresponding male sterilization on the expression of resistance to ergot disease revealed that these may be hidden sorghum ergot disease resistance genes.

Rapid screening method for evaluation of IskenderTiryaki,<a href="http://www.oakleybrillen.org" target="_blank" class="postlink">oakley brillen</a>, DavidJ. Andrews germination and seedling growth of sorghum planting date is particularly sensitive to cold temperatures. Under cold temperature conditions in the poor seedling emergence and seedling losses will lead to reduced plant population and grain production. Improved germination and seedling early development of cold tolerance of sorghum production can be expanded to colder climates; and the sorghum planted earlier may provide many advantages such as avoiding the substantial biological stress. Rapid growth in early season can reduce the secondary pests, diseases and drought effects. Gmxtner et al (1987) growth chamber with cool temperatures in the nursery and field screening test and freezing cold temperature tolerance of the germination of corn group,<a href="http://www.uggstiefele.com" target="_blank" class="postlink">ugg stiefel</a>, found that cold temperature stress in seedling vigor and emergence of the next selection can significantly improve these traits. Nursery at a cool temperature tolerance option to increase the yield of direct and effective. Room selection in the nursery and growth of slightly improved freeze tolerance of freezing (a 2 ~ C) patience. Miller et al (1984) proved that the cold temperature tolerance of sorghum should be in the early evaluation of germination and seedling growth, and they can not be that accurate, reliable and economical screening method. Some people have been identified germination, emergence and seedling growth is independent of temperature sensitive to cold. Singh (1985) found that the level of cold tolerance in sorghum is a plant growth period with the change. Because in the warm spring or high-altitude cold temperature conditions are generally want a quick germination and planting, so the variation of cold tolerance with agricultural importance. The purpose of this study was to find a way to reliably determine the germination of sorghum under controlled conditions easy way to cold tolerance. This test evaluated the determination of cold temperature tolerance of 3 methods: 1. Room temperature in the greenhouse and growth chamber germination rate in the cold temperature germination rate under stress compared and seedling germination in a few time record; 2. Comparison of the same genotype in the greenhouse and growth chamber conditions, the final germination%; 3. By comparing the room temperature and cold temperature conditions, the seedling growth of several time periods to measure seedling growth rate, and the data rate of emergence and early seeding of the field for comparison. L2 genotypes and their use of crosses carried out five tests. To estimate cold tolerance, for a total of 36 genotypes were compared. These kinds of strains and the control is based on the initial evaluation of cold tolerance at germination and the result, from 1997 early sowing of field trials selected. The results showed that at room temperature conditions (day 25 ~ 30o (=, night 20 ~ 25 ~ C) and cold temperature stress conditions (constant l5o (=) between genotype germination and seedling growth rates have the biggest difference. under the control of cold temperature and cold temperature germination rate of field emergence tests highly correlated with early sowing (P <0.01). This study shows that under controlled conditions to test two kinds of Ru, the measured seedlings under normal temperature conditions growth rate and cold-temperature stress conditions (15 ~ C) the germination rate and record the best time of the data, which is in the field before the final evaluation of the effective screening of genotypes of cold tolerance of great help.
