Comparison of Agronomic Traits According to Plant Types before Wintering in Malting Barley Lines

맥주맥의 월동전 초형에 따른 주요 형질의 비교

So as to compare the differences of major agronomic traits according to fall plant types, two cultivars and eight lines which were derived from the same pedigree, were planted and analyzed. The heading and mature times, and culum length of erect plant types were earlier or longer, but the spike number per ㎡ and yield were smaller than the those of prostrate types. Also, 1000 grain weith, assortment rate and light penetration rate in erect types were greater than in prostrate types. The heading time was positively correlated with mature time and yield, but negatively correlated with culum length, 1000 grain weight, assortment rate and light penetration rate. Yield was negatively correlated with light penetration rate. If the lines with prostrate types in fall season, fast regrowth after wintering and rapid elongation of stem were bred and selected, it will be of great benefit in the area requiring sever winter hardiness.

보리의 월동전 초형에 따른 농업형질의 차이를 비교하고저 같은 교배조합에서 선발, 고정시킨 계통 및 교배친 10개를 공시하여 분석한 결과는 다음과 같다. 1. 포복형에 비해서 직립형 계통은 출수기 및 성숙기가 빠르고, 간장은 컸으나 $m^2$당 수수, 수량성은 적었다. 또한 천입중, 정입률, 광투과율은 컸다. 2. 출수기는 성숙기, 수량과 정상관, 간장, 천입중, 정입률, 광투과율과 부상관이 있었다. 수량은 광투과율과 부상관이 인정되었다. 3. 월동전에 초형이 포복형이면서, 월동후 생육재생기가 빠르고 식간신장이 빠른 계통을 육성, 선발하는 것이 특히 내한성이 요구되는 지역에서 유리할 것으로 생각된다.
