Abstract: To clarify the fertility and adaptability of main application oat varieties in Bashang of Hebei, the authors analyzed the average yield, coefficient of variation of the high yield test results of 6 oat varieties for 7 years (2009-2015), identified that,‘bayan 4’and‘bayou 3’could be classified as the special varieties of forage,‘baiyan2’,‘bayou 9’and’bayou 1’could be classified as the special varieties for processing, earlymaturing varieties‘bayou 6’and‘baiyan 2’could be used as the relief varieties in single cropping area, and more adapt to the two cropping area. The results showed that: (1) under good soil fertility level, the average grain yield from high to low was:‘bayan 4’>’bayou 6’>’bayou 1’>’bayou 9’>’baiyan 2’>’bayou 3’; the average yield of biomass from high to low was:‘bayan 4’>’bayou 3’>’bayou 1’>’bayou 9’>’bayou 6’>’ baiyan 2’; (2) under good soil fertility level and weather condition, hulled oat variety‘bayan 4’got the highest grain yield of 6861.0 kg/hm2 and the highest biomass of 14571.0 kg/hm2 in 2009; naked oat variety‘bayou 6’ had the highest grain yield of 5494.5 kg/hm2 in 2012,‘bayou 3’had the highest biomass of 12507.0 kg/hm2 in 2014;‘bayan 4’and‘bayou 6’were most potential varieties for grain yield; (3) the varieties had good resistance and relatively stable yield, and adapted to different application directions and planting areas. The experiment fulfilled both seed production and variety evaluation.
