Variability and relationship among different morpho-phenological traits for twenty four lines/varieties in each of the two winter and facultative barley trials were studied at two locations (Tel. Hadya and Breda) in northern Syria. A significant variation was observed in barley lines for grain yield, plant height, days to heading and maturity, grain filling period and growth period. Since the winter during 1994-95 was mild at the both locations and drought and high temperatures were major stresses, most of the high yielding genotypes were facultative types. A significant positive correlation was found between plant height and grain yield. There was, however, significant negative correlation between grain yield and days to heading and maturity. Grain filling period was positively associated with yield (except for winter types at Breda). A negative correlation between growth habit and yield at both locations can be attributed to mild winter and severe drought and high temperatures during crop growth period.
85 new wheat selections were assessed and compared with the three standard local checks based on the combined analysis in five preliminary wheat yield trials. The combined analysis has the advantage by improving the selection efficiency of the new genotypes tested in different yield trials conducted in the same year and location. Seven out of the total selections tested out yielded the standard check varieties after making the adjustments in the treatment means. This analysis gave an equal chance to the new selections tested in the different trials which otherwise may have been overlooked.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
