Abstract : |
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. , |
