The dormant seeds were treated with 15 Kr of X-rays. Method A : After 3 ears were havested from each X1 Plant and one grain was removed from each ear, these grains were planted in bulk at X2 Mlethod B : After one ear was harvested from each Xl plant, the grains were planted separately as ear progenies at X2Method C : After 3 ears were harvested from each Xi Plant, the grains were planted separately as plant progenies at X2 Method A was compared with B and C. The eharacters mainly analyzed were earliness and stems;shortness. The selection of such aberrants was carried out in X2 (Table 1), and these were confirmed as mutants in X3 (Tables 2 and 3) . In the case of method A-ll (Table 1), selection was made by measuring stem length at X2 generation. In the case of other methods, selection was made by observation. 1) By using method A, the mutant types found n X2 Were more frequently observed compared with the other two methods and the mutant much deviated from the parent type were involved.This result was compatible with the theoretical consideration of YOSHIDA (1962). 2) Much better selection of short stem mutants was made in X2 by method A (I+II) than by methods B and C. This result demonstrates that the individual selection using this measurement was made much better than the pedigree selectian through observation.","PeriodicalId":270267,"journal":{"name":"Japanese journal of breeding","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1963-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124687400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the sake of this observation, the authors have adopted MUNSELL'S color system of which descriptions are considered to be properly objective than the ordinary system. The frequency of appearance of pigments in fourteen characteristics in rice plant is very high in the inner part of leaf sheath, internode, septum, apiculus and stigma at heading stage and in apiculus at maturity stage. Especially, the anthocyanin pigments are observed in all the characteristics in rice plants, while no other pigments are observed in all the characterstics except in the following fcur characteristics ; namely, septum and pulvinus or node at heading stage and apiculus, Iemma and, palea at maturity stage (Table 1). The symbolized color shown according to MUNSELL's 'color system for each charccteristic in rice plant shows a wide range in the hue, value and chroma for the characteristics of septum at heading stage, and apiculus and lemma or palea at maturity stage. The hue shown by MUNSELL'S color system in rice plant is expressed by RP, R, YR and Y, and the anthocyanin pigments are limited to RP (Table 2). In regard to anthocyanin pigments in characteristics of rice plant the data obtained show similiar tendencies to the previous reports (Fig. 1). Taking these results into consideration, only five charctersitics were finally selected for the purpose of the possible discrimination of rice varieties ; namely, innerpart of leaf sheath, septurn and apiculus at heading stage and apiculus, Iemma or palea at maturity stage. Besides MUNSELL'S color system, a method of showing color in numerals was adopted, and the classification of about half of the rice varieties having color pigments was accom-plished by this method (Table 3).","PeriodicalId":270267,"journal":{"name":"Japanese journal of breeding","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124442336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
