Effect of photoperiod on the thirty winter and spring wheat cultivars vernalized was studied in the green house controlled under the temperature of 25℃ (day) and 20℃(night), and at the photoperiod from 8 to 24 hours. Among the wheat cultivars tested, there showed less heading response by photoperiod increased in early maturing cultivars than that in late maturing cultivars. More differences of cultivars in heading appeared under shortday condition than that in long-day condition.

The vernalization periods required for various classes of growth habit in wheat and barley was studied in the fall sown cultivars at Suweon. The vernalization requirement for those I-VI class of winter growth habit was almost completed before the end of the year (81 days after sowing).

Origin, dessemination and utilization of semi-dwarf genes of wheat were studied. Begining of wheat cultivation in Korea was about 3000 years ago and varietal name was given around in 1400 A.D. Original population carrying semi-dwarf genes was found to be Korean native Anzunbaengimil or Nanjangmil which was introduced to Jappan in the period of 1904~1905 and presumably renamed as Daruma. Genetic resemblance of these two populations was discussed. Number of pure-line selections were made from this population and Norin 10 was released in Japan by utilizing this semi-dwarf genes. Korea also released Suweon 92 and Seuseun 27 using same gene sources. Contribution of this semi-dwarf genes to the increase of world wheat production was reviewed. Semi-dwarfing genes of wheat which extended a great contribution for increasing wheat production in the world were investigated on their origin, dissemination, and utilization and the results were summarized as followings. 1. Begining of wheat cultivation in Korea was postulated to be about 3000 years ago considering the history of wheat cultivation of China and Japan. 2. Wheat varietal name was recorded as early as in 1482. However, Nongsajiksul published in 1400 has a brief description about wheat (cultural) methods. Therefore, it is not difficult to presume that varietal name was available to that time. 3. Original population where the semi-dwarf plants were selected were Anzunbaengimil or Nanjangmil which were distributed all where in Korea in the period of 1500~1941. This population had great variation in plant height, presumably a mixture with individuals carrying Rht₁, Rht₂ or Rht₁ Rht₂. 4. Dissemination of Anzunbaengimil to Japan was possiblly made during the period of Imjin Japanese Invasion to Korea, or by the Japanese Agronomists who were dispatched to Korea for investigation of agriculture and land productivity from 1901 to 1905. 5. Anzunbaengimil(Crippled wheat) may be named as Daruma(crippled wheat) after introduction to Japan or renamed as Daruma after pure-line selections were made. Considering such traits as growth habit, glume color, plant, height grain color and plant type it was concluded that Daruma is orginated from Auzunbaengimil population. 6. In Japan, semi-dwarf gene from Daruma population have been utilized extensively and released Norm 10 which became an important world wide breeding material. Seuseun 27 and Suweon 92, the Korean semi-dwarfs, were also improved using same dwarf gene source as Norin 10. 7. Dwarf genes from Daruma population, have contributed for improving several early maturing and high yielding wheat varieties in Korea such as Suweon 85, Chokwang, Suweon 215, 216, 219 and 220. 8. Norin l0/Brfvor 14 was the dwarf gene source for improving Cains and Nugains at Washington State, USA and CIMMYT semi-dwarfs. Coullee, a hard white winter wheat, was improved using Suweon 92, and Seuseun 27 was utilized for improving Tam Wheat and Holley wheats at Texas A&M, USA.

맥류의 세대촉진방법에 관한 연구 IV. 수원지역에서 소맥 1년 2기작 세대촉진재배

To establish a generation acceleration technique, two crops a year at field condition of Suweon, 10 varieties different in their spring growth habit were tested with 6 different seeding time after harvesting. These materials were harvested on June 10, 19, 79 and tested for their seed production ability at varions seeding time from July I I to August 15 with a week interval. An immatured seed germination technique and green vernalization methods were applied in cycling generations and the results obtained were summarized as follows. 1. In summer growing, seedlings establishment after transplanting was better in earlier transplanting. 2. Heading time was remarkably enhanced by earlier transplanting. Considering the results of two years early or mid of July was the suitable time to plant the second summer crop. 3. Those varieties of spring growth habit expressed little variations in plant height among the varieties. In 1978 which is referred as warm year produced plant height as tall as 8-16cm and poor crop but produced good crop with 25-65cm plant height in 1979. 4. No definit tendency in the length of spike was. observed among the cultivars but longer spike was found in winter wheat compared to the spring. 5. Number of spikes per plant was ranged from 1 to 3 regardless the transplanting time in 1979. However, more spikes per plant were produced in early or mid of July transplanting and those varieties of higher growth habit than V did not produces any spikes. 6. Higher number of grains per spike was found at earlier transplanted varieties. Therefore, it is concluded that those materials of I-IV growth habit with mid or early July transplanting would be suitable in practical sense considering their ability of seed production. 7. Two-year results indicated that wheat crop can not tolerate the temperature level higher than average 32$^{\circ}C$ C at Suweon. In this regard, the cultivation schedule was established assuming average temperature condition like the year of 1979 which was possible to grow wheats.
