영문 초록

In order to examine the possibility of the growing two generations in one year of segregating wheat and barley populations, three wheat and three barley varieties were direct seeded and transplanted after vernalization while F₃ wheat and barley populations were transplanted following vernalization at an alpine location during the summer season. These results showed that with wheat and barley segregating line: with a winter growth habit grade of less than IV, it was possibly to grow two generations in one year by using the methods of germinating the immature seed and seed-green vernalization, and the transplanting at Daekwanleung before early part of July. This experiment tested the possibility of growing two generations of wheat and barley in one year in Korea by growing a summer generation at the alpine location of Daekwanleung. A winter generation was grown at either Suweon, Mooan or Cheju in Korea. The results are as fellows: 1. All the wheat and barley varieties with a winter growth habit grade of less than IV headed when direct seeded at Daekwanleung before than May 25. 2. The adequate seed-green vernalization period for both barley and wheat was 30 to 35 days and the proper transplanting time after vernalization was late June to early July. 3. Wheat and barley segregating lines with winter growth habit grades of less than IV can produce to generations in one year by using the methods of germinating the immature seed and seedgreen vernal ization, if transplanting occurs at Daekwanleung before the early part of July.
