This study was conducted to establish the techniques of the continuous wheat production of high yield level and to standardize of quality uniformity. It was selected the experimental places which were Iksan of Jeonbuk, Gwangju metropolitan city and Hapcheon of Gyeongnam. Farmers of participating in the experiment were 13 persons with two types of advanced and lower levels of their techniques in wheat cultivation, and total numbers of fields were 22 fields. The common information on the field soils were silt loam and loam in soil textures, all most deep and some moderate in soil depth, imperfectly drained in drainage classes, coastal and interior plain with some alluvial fan or local valley in land topography. It was investigated in status of the physico-chemical properties of soils. Soil pH was 6.0 in mean values with 5.2 ~ 7.5 ranges, organic matter(OM) was 25 g/kg with 16 ~ 39 ranges, available P2O5 194mg/kg with 47 ~ 586 ranges, available SiO2 164mg/kg with 57 ~ 454 ranges, in exchangeable cations, K was 0.46 with 0.20 ~ 0.98, Ca was 6.2 with 3.6 ~ 11.7, Mg was 1.8 with 0.9 ~ 3.4 cmol(c)/kg in ranges, and these properties of soils were higher in advanced than those of lower level farmers. The amounts of fertilization in N-P2O5-K2O were 184-49-50 kg/ha in farmers application, 108-114-47 kg/ha in soil testing and 94-83-41kg/ha in standard recommendation. Fertilizer application amounts by farmers were higher than those of soil testing and standard recommendation by 76 ~ 90 kg/ha in N and 3 ~ 9 kg/ha in K2O, and less by 34 ~ 74 kg/ha in phosphate fertilizer.

Rye has been a major winter forage crop in Korea. Varietal improvement of rye has been practiced either by hybrid or population breeding systems. Hybrid breeding offers important advantages over population breeding since it is normally a cross-pollinated crop. The hybrid breeding in rye has been possible since cytoplasmically inherited forms of male sterility (CMS) and corresponding nuclear restorer genes were found. The objectives of this research were to develop the maintainer and restorer lines of Korean inbred lines and to estimate the effect of 'Pampa' type of CMS cytoplasm on yield and its related characteristics. For easy discrimination of male-sterile status of plants, anther scoring and the restore index system in which seed-setting and pollen quantity of viability were taken into account were established. High significant correlation between pollen quantity and pollen viability was found. For "Pampa" cytoplasm, four of 14 Korean inbred lines tested turned out to be a maintainer but no restorer was found. But for "235b" CMS cytoplasm, seven inbred lines acted as complete restorers. The Korean inbred rye lines acted mainly as maintainers in "Pampa" cytoplasm but acted mainly as restorer in "235b" cytoplasm. The 'Pampa' cytoplasm inducing male sterility reduced cohn length and plant height and increased the number of tiller, so forage yield and grain yield were enhanced. However, heading date was slightly delayed compared to the normal cytoplasm.elayed compared to the normal cytoplasm.

메보리 (겉보리 10품종과 발보리 12품종)와 찰보리 8품종 및 벼, 밀을 공시하여 Amylose함량, 수분흡수율, 호화조건등에 관하여 시험한 결과를 요약하면 다음과 같다. 1. Amylose함양은 메보리 23.4∼31.5％, 찰보리 5.4∼9.5％였다. 2. 수분흡수율은 찰보리에서만 Alkaline수분흡수율, 분수분흡수율, 곡립수분흡수율간에 상관관계가 있었다. 맥종간 3가지 수분 흡수율은 모두 찰보리>겉보리>찰보리 순으로 높게 나타났다. 3. 찰보리는 메보리보다 최고점도와 최저점도의 차가 훨씬 크고 메보리는 점도가 떨어지다가 다시 올라가는데 찰보리에서는 다시 상승되는 경향을 볼 수 없었고 호화된 용액을 식했을때 찰보리는 gel상태로 굳지 않고 액체상태로 있었다. 4. 호화온도는 쌀보리의 경우가 제일 높았으며 다음이 겉보리 다음이 메벼, 찰벼, 밀의 순서였으며 쌀보리의 경우가 제일 낮았다. 5. Amylose함양과 호화온도, 호화시간, 점도와는 .상관이 없었다. 6. 호화시간은 호화온도가 낮은 것은 길고 높은것은 짧아서 최고점도에 도달되는 시간이 맥종별로 거의 일정하였다. 7. 호화온도는 최고점도시온도, 호화시간. 최고점도, 최저점도와 상관이 있었고 호화시간과 최고점도와도 맥종간 모두 고도의 정의 상관이 있었다. 8. 호화시간과 최저점도, 최고점도와 최저점도는 겉보리와 쌀보리에서는 상관이 있었으나 쌀보리에서는 상관이 없었다. 9. 쌀보리에서는 경도와 수분흡수율, 정맥비율과 고도의 상관관계가 었었다.
