Abstract
This experiment was conducted to evaluate the main effects and pleiotropic effects of two comparable isogenic lines for culm and spike length in hulled barley and observed various agronomic characteristics, yield and yield components under the conditions of heavy fertilizer application and high planting densities. Three isogenic lines, culm, spike and culm and spike, were planted and to obtain basic data for improving high-yielding and quality of hulled barley at Experiment Farm, Dankook Univ., Cheonan city in 1985. Differences of culm length between two comparable isogenic lines, short culmed line (SCL) and medium culmed line (MCL), in isogenic lines for culm length showed highly significant differences. And differences of spike length between two comparable isogenic lines, short spike line (SSL) and medium spike line (MSL), in isogenic lines for spike length showed highly significant differences. Differences of culm and spike length between two comparable isogenic lines, short culmed and spike line (SCSSL) and medium culmed and spike line (MCMSL), short culmed and spike line (SCSSL) and long culmed and spike line (LCLSL), in isogenic lines for culm and spike length showed highly significant differences. Characteristics affected highly by the genes of culm length in isogenic lines for culm length were heading days, the 1st and 2nd internode length, No. of grains per spike, No. of spikes/m
피맥의 다수확을 위하여는 다비, 밀식재배를 하여야 하며 이때에 문제가 되는 것은 도복에 의한 감수이다. 이러한 중요성에 비추어 피맥 7개 조합을 공시하여 간장과 수장의 대응이 되는 isogenic lines 을 만들어 다비, 밀식재배조건하에서 간장 및 수장의 차이에 따른 유전자의 주효과와 다면적효과를 구명하고 농업형질에 미치는 영향을 알아 양질 다수성 품종육성을 위한 기초자료를 얻고저 시험하였는바 그 결과를 요약하면 다음과 같다. 1. 간장동질유전자계통에서 단간계통 대 중간계통, 수장동질유전자계통에서 단수계통 대 중수계통, 간장과 수장 동질유전자계통에서 단간단수계통 대 중간중수계통, 단간단수계통 대 장간장수계통간에는 간장 및 수장의 주효과와 다면적 효과에 고도의 유의성을 보였다. 2. 간장동질유전자계통에서 간장유전자의 영향이 큰 형질은 출수일수, 제1, 2절간장, 수당립수, m
