Abstract

This study was conducted to investigate characteristics of panicle traits which are important factors affecting yield and grain quality of rice. Twelve panicle traits in 178 Korean rice varieties composed of 160 Japonica type varieties and 18 Tongil type varieties were investigated. Tongil type varieties had longer panicle and thicker neck node than Japonica type varieties. Other traits such as number of total spikelets, total rachis-branches, secondary rachis-branches (SRBs) per panicle, total spikelets on SRBs per panicle, mean number of spikelets on a SRB, and mean number of SRBs per primary rachis branch (PRB) in Tongil type varieties were also higher than in Japonica type varieties. On the other hand, Japonica type varieties were shown to have well exserted panicle and little more mean number of spikelets on a PRB than Tongil type varieties. According to cluster analysis based on 12 panicle traits, 178 varieties were divided into four main groups. Group I had 133 Japonica type varieties and was characterized by relatively well exserted short panicle, small thickness of neck node, few rachis-branches and little sink size than other group. Group II was composed of 24 Japonica type varieties and 6 Tongil type varieties showing medium value and range between Group I and III. Group III included 11 Tongil type varieties and 1 Japonica type variety 'Baegjinju1' characterized by relatively poor exserted long panicle, big thickness of neck node, many rachis-branches and large sink size. Group IV was solely composed of 'Nongan', which had well exserted long panicle, big thickness of neck node, many rachis-branches and large-sink size. In correlation analysis, number of total spikelets per panicle showed very high correlation with the number of total rachis-branches per panicle (r=0.975), number of spikelets on SRBs per panicle (0.962), number of SRBs per panicle (0.959), mean number of SRBs per PRB (0.746) and mean number of spikelets on SRBs (0.738).

국내에서 육성된 178개 품종을 이용하여 12개 이삭형질에 대한 검토 결과는 다음과 같다. 통일형이 자포니카형보다 이삭길이는 길었고 이삭목은 두꺼웠다. 또한 수당립수, 총지경수, 2차 지경수, 2차 지경 총립수, 2차 지경 평균립수 및 1차 지경당 2차 지경수 각각에서 많았다. 반면에 자포니카형이 통일형보다 이삭추출은 양호하였고 1차 지경 평균립수도 약간 많았다. 12개 이삭형질 값을 가지고 평균 연결법을 이용하여 178개 품종을 대상으로 군집분석을 한 결과 4개 그룹으로 분류할 수 있었다. Group I은 자포니카형 133품종, Group II는 자포니카형 24품종, 통일형 6품종, Group III은 자포니카 1품종, 통일형 11품종, Group IV에는 농안벼가 포함되었다. 12개 이삭형질간 상관관계를 분석한 결과 이삭목 두께는 이삭길이, 2차 지경 총립수 및 수당립수와 높은 정의 상관관계를 보였다. 수당립수는 총지경수, 2차 지경 총립수, 2차 지경수, 1차 지경당 2차 지경수, 2차 지경 평균립수와 정의 상관을 보였다. 총지경수는 2차 지경수, 수당립수, 2차 지경 총립수, 1차 지경당 2차 지경수와 정의 상관을 보였다.
