| Abstract: | Based on the 43 lines from indica and japonica hybridization,the test determined ADi and correlation of indicators,the results indacated that except that the first and second panicle node lengths distributed indica-clinously,other characters distributed japonica-clinously.There were significant correlation among 6 subspecies characteristics and it showed nonrandom collection. |
