The effect of sites and years on the technological quality of winter wheat grain
2005
J. Kučerová
The results of three-year trials (1999 to 2001) conducted with six winter wheat varieties in which was investigated the effect of sites, years and varieties on the final grain yield and technological quality showed statistically significant differences (LSD, 95%) among sites in grain yield and these parameters of quality: test volume mass, wet gluten content, sedimentation test, protein content, falling number and flour water absorption capacity. As to the quality, the Žatec site showed itself as generally most suitable, and the Jaroměřice site as the least suitable one. Climate conditions showed a statistically significant effect (LSD, 95%) on grain yield and all quality parameters, beside the percentage of complete grains and swelling capacity of gluten and falling number, which were insignificant. The most favourable weather conditions, a lot of precipitation and high temperature in the course of ripening from three years were proved in the year 2000. Among the varieties were statistically significant differences (LSD, 95%) in grain yield and these parameters of quality: test volume mass, thousand grain weight, ash content, percentage of complete grains, sedimentation test, protein content, reologic properties of dough and baking tests. From the six varieties the best profits were shown from variety Sulamit (loaf volume 595 ml/100 g of flour), the worst was Semper (loaf volume 543 ml/100 g of flour) and Vlasta (loaf volume 532 ml/100 g of flour). The best grain yield was in 2001 (average of sites 8.84 t/ha) and the variety Semper had the highest grain yield of 9.17 t/ha, that is higher at 13.41% compared with Sulamit (7.94 t/ha).

Effects of winter wheat cover crop desiccation times on soil moisture, temperature and early maize growth
2005
B. Stipešević | E.J. Kladivko
Two tillage systems for maize (Zea mays) after soybean (Glycine max), no-till (NT) and conventional till (CT), which consisted of double disking in the spring, were included in the experiment on two sites in Indiana, USA. Each tillage plot had three winter wheat (Triticum aestivum L.) cover crop levels: no cover crop (N), early desiccation (E), 3-4 weeks prior to planting the maize, and regular desiccation (R), within the maize planting week. Due to the mulching effect, both E and R for both tillage systems increased soil moisture, except in the case of spring drought, when E proved dominant. Soil temperature for both tillage systems showed N > E > R order. Young maize plants tended to grow taller and have greater shoot biomass in NT than in CT. Both E and R improved early maize growth. In the case of drought, the E proved significantly better for maize on both tillage treatments, due to the better soil water conservation, therefore the winter wheat cover crop should be desiccated early in given climate conditions.

N. Singh | R.K. Behl | M.S. Punia
Two high yielding wheat (Triticum aestivum L.) varieties were pollinated with seven agrarian superior varieties. F1's thus obtained were pollinated with diverse winter maize lines/composites and treated with a solution containing 2,4-D and GA3. The haploid embryos were rescued 13 to 16 days post pollination on MS1 and MS4 media. Out of 15, only two crosses viz., (UP 2338 × HD 2285) F1 × maize and (WH 533 × PBW 343) F1 × maize resulted in callus development and direct germination via embryo rescue.

This investigation was undertaken to study and analyze the quality of wheat products of different milling systems in central plain, western plain and western regions of Punjab. A significant difference in the quality of different milled wheat products in different milling systems has been found. The dry gluten (), crude protein () and free fatty acid () of whole wheat flour of water flour mills is not significantly different from large and small roller flour mills in all regions. The wheat flour and wheat semolina which are milled wheat product of roller flour mills only are non-significant between large and small roller flour mills except the crude protein () in central plain region for large roller flour mills is significantly higher than the small roller flour mills. The crude protein() and the particle size (mm) of bran of different milling systems in all the regions is found significantly different from one another. The porridge which is a milled wheat product of Automatic large scale flour mill, common flour mill, Rajasthani flour mill has a significant difference at 5 level of significance from one another for all the regions.

Drought stress as the most important abiotic stress plays an important role in yield reduction of crop plant world wide . The study of physiological responses of different wheat varieties to water stress could be a useful tool to understanding of the mechanisms of drought resistance. This study was conducted in Iran , Yazd ( semi- aried region) , to compare end season drought tolerance of 6 wheat lines and cultivars that release from a national plan. Each lines and cultivars planted in 12 m-2 area . The experiment arranged as randomized complete block design with three replications . Results indicated that there was significant difference between lines and cultivars for grain yield, plant height and grain number per main spike. However thousand grain weight and main spike height was not significant difference.WS-16 and WS-7 produced the highest grain yield by 3030 and 2972 kg.ha-1 ,respectively .
