초록

초다수성 품종 개발의 기초자료로 활용하고자 새로이 도입된 신초형 소얼 수중형 유전자원을 이용하여 F$_2$-F$_{5}$상관에 의한 sink-source관련 형질의 유전력을 추정한 결과를 요약하면 아래와 같다. 1. 일품벼에 YR15965 Acp 33이 교배된 F2와 F5세대간 상관정도에 의해 추정된 sink 및 source관련 형질들의 유전력은 specific leaf area, sink-source ratio와 harvest index의 0.009, 0.121, 0.013을 제외한 모든 형질에서 0.224이상의 높은 유전력을 보였다. 2. IR 66738-118-1-2에 가야벼가 교배된 후대에서는 모든 sink 및 source관련 형질이 0.001-0.286의 낮은 유전력을 보였다. 3. Sink 및 source관련 형질들과 수량과는 두 조합 모두 높은 싱관정도를 보였으나 등숙률과는 IR 66738-118-1-2에 가야벼가 교배된 후대에서는 대부분의 형질이 상관이 없었다. 그러나 일품벼에 YR 15965Acp33의 교배 후대에서는 등숙율과 source형질과는 높은 정상관이, sink capacity와 sink-source ratio등 sink형질과는 유의한 부의 상관이 있었다.

The heritability of sink-source characters was estimated by regression coefficient between F$_2$ and F$_{5}$ in two crosses of IR 66738-118-1-2/Gayabyeo and the Ilpumbyeo/YR 15965 Acp 33. In order to get the some basic information for breeding of high yielding rice, genetic resources of new plant type with low tiller and heavy panicle were used. Most of the sink and source characters in Ilpumbyeo/YR 15965 Acp 33 cross showed high heritability over than 0.224. But the specific leaf area and sink-source ratio displayed low heritability being 0.009 and 0.013, respectively. Heritability of all sink and source characters in IR 66738-118-1-2/Gayabyeo cross ranged from 0.115 to 0.247. Correlation coefficient between yield and yield components in both combination were in the ranged between 0.001 and 0.247. But correlations among the yield components were not significant. Correlations between the yield and sink-source characters in both combinations were also highly significant. Particularly, correlation between the grain tiling ratio and most of the sink-source characters in IR 66738-118-1-2/Gayabyeo cross were not significant. In Ilpumbyeo/YR 15965 Acp 33 cross, correlations between grain filling ratio and source characters were positively significant. but sink characters (sink capacity and sink-source ratio, etc) were negatively significant.
