マニプール州はアッサム州の南東に位置し,アジア栽培稲の.多様性中心地の一角を占めている.ここで収集された在来稲鼎種は約270のMRC (Manlpur Rice Collection)として整理され,農業特性が調査されているが,その一部の譲渡を哩けて2,3の生埋的・形態的特性と葉緑体および全DNAの解析を行い,各品種ごとの遺伝的特性とその栽培地域との関係から牛.態種の分化の様相を明らかにした 供試材料はマニプール州の'在来品種.51と改良型10品種.で,対照としてJaponica5(日本品種3といわゆるJavanica2)品種及びIndica2品種を用いた(Tab1e1).まず内外穎のフェノール反応,2〜3葉期の苗の1.5%塩素酸カリ溶液に対する抵抗性,および穎毛の長さを用いた判別関数Z他による48在来品種0)分類では,32品種がIndica,5品種がJaponica,11品種が中間型となった.
The Manipur State of India is considered as a part of the center of diversity of Asian rice. To obtain information on the genetic diversity and subspecies differentiation in local rice cultivars from the area, a survey was made of selected morphological and physiological traits, chloroplast DNA (CtDNA) type, and total genomic DNA polymorphism. Judging from the discriminant score z, 32 out of 48 tested local cultivars were classified into indica , 5 into japonica , and 11 intermediate. An analysis of ORFIOO of CtDNA by PCR identified 29 cultivars as deletion type (indica ), and 22 as non-deletion type Japonica ). Random amplified polymorphic DNA analysis revealed a high degree of polymorphism in the 51 cultivars, and 4 major clusters were recognized in a dendrogram constructed by UPGMA: 29 cultivars formed a cluster with typical indica standards
