Comparative Studies of Introduced Rey ( Secale Cereale L. ) for Spring Forage Production IV. Winter-hardiliness and forage production of selected winter rye varieties under upland condiions
초록
These experiments were conducted at the upland of Livestock Farm, Seoul National University, Suweon to determine the growth characteristics, winter-hardiness and forage yield of selected southern and northern-types of winter rye (Secale cereale L.) in comparison with the Korean native rye over two seasons, 1977-78 and 1980-8 1. During the 1977-78 season, most southern-type rye varieties except Explorer and Abruzzi headed 2 to 6 days earlier than the Korean native rye and 6 to 10 days earlier than northerntype rye varieties Rymin and Puma, while in 1980-81 southern-type rye varieties headed 5 to 7 days earlier than the Korean native rye, therefore, the Korean native rye seemed to be medium in maturity. There were no significant differences in winter-hardiness among different rye varieties with the exception of the lowest winter survivals of Wintergrazer 70, Explorer and triticale, and Gator, Explorer and Florida Black during the 1977-78 and 1980-8 1 seasons, respectively. Southern-type rye varieties tended to yield more forage than northern-type and the Korean native rye varieties when harvest was made in the later part of April. During 1977-78 season, Vita-Graze, Elbon and Athens Abruzzi rye varieties produced significantly more forage than the Korean native rye, but in 1980-81 Wrens Abruzzi rye produced significantly more forage than the Korean native rye. Based on the results of the two seasons, southern-type rye varieties,Vita-Graze, Athens Abruzzi, Elbon and Wrens Abruzzi could be recommended as a source of green forage for livestock in April in middle-northern parts of Korea.
