Title Alternative カクヤリグサ科一年生雑草における数量分類学的研究
FullText URL 002_001_123_134.pdf
Author Muhamad Ahmad, Chozin| Satou, Kazuhiro| Yasuda, Shozo|
Abstract Three species of Cyperaceous weeds, Cyperus iria (12 strains), C. microiria(12 strains) and C. amuricus (6 strains), were collected from different sites of Okayama, Tottori and Tokyo prefectures, and various morphological characters, biomass and seed production were observed on the plants which were cultivated at Kurashiki. The analysis of variance showed a significant difference among the strains in each character. However, the species overlapped with each other in most morphological characters. Prinipal component analysis on the 21 characters showed that 83% of the total variation could be explained by the first three components: the first component (37%) was regarded as factors concerning spikelet and seed production; the second component (28%) was regarded as factors concerned the size of vegetative parts; the third component (18%) was largely affected by seed weight and floret density. Scatter diagram on the first and third principal components showed that the 30 strains of three species divided into three groups, and strains in each group correspond to the three species without exception. Based on the second and third principal components, strains of C. microiria were further divided into three sub-groups according to size of vegetative parts. Using the cluster analysis, 30 strains of these species were divided into four large clusters; the first was composed of C. amuricus strains, the second was of three strains of C. microiria, the third included the remaining strains of C. microiria, and the last cluster was composed of C. iria strains. It may be concluded that C. microiria is composed of two or three ecotypes which are different in morphological and reproductive traits.
Abstract Alternative カヤツリグサ科の3種の雑草カヤツリグサ(C.microiria Steud.)12系統、コゴメガヤツリ(Cyperus iria L.)12系統およびチャガヤツリ(C.amuricus Maxim.)6系統を岡山県、鳥取県および東京都なら採集して倉敷で栽培し、形態的特性、バイオマスおよび種子生産性など21形質を調査した。各形質を分散分析したところ系統間差はいずれも有意であったが、種間の値は多くの形質で重複し、単一形質による種の判別は困難であった。21形質間の相関行列を主成分分析したところ、上位3主成分の累積寄与率は83%と大きく、第1主成分(37%)は小穂の形態と種子生産性、第2主成分(28%)は生長量、第3主成分(18%)は種子重と小穂密度とそれぞれ関係が深いとみられた。第1主成分と第3主成分によって供試30系統は3群に分けられ、各群はそれぞれの種と一致した。さらに、第2主成分と第3主成分によってカヤツリグサ種内の系統は主として生長量の異なる3群に分類できた。クラスター分析によって供試30系統は4つの大きな群に分けられた。一番目の群には、C.amuricusの全系統、二番目の群にはC.microiriaの3系統、三番目の群にはC.microiriaの残りの系統、および最後のクラスターにはC.iriaの全系統が含まれた。従って、C.microiriaha形態的および生態的形質において異なる2ないし3の生態型から成ると考えられた。このように数量分類学あるいは多変量解析はカヤツリグサ科の雑草の種間ならびに種内の分類に極めて有効な解析法であることが示された。

Title Alternative 日本とカナダの春播オオムギから採取した大麦網斑病菌株の病原性の変異
FullText URL 001_002_147_158.pdf
Author Sato, Kazuhiro| Takeda, Kazuyoshi|
Abstract Twenty-two isolates of Pyrenophora teres Drechs. collected from Japanese and Canadian spring barleys were inoculated to 38 barley varieties having various genetic backgrounds. The analysis of variance for the discase ratings showed that there were significant differences both in the virulence of isolates and the resistance of varieties. However, the interaction among isolates and varieties was not statistically significant. Both Finlay-Wilkinson regression analysis and principal component analysis by Additive Main effects and Multiplicative Interaction effects(AMMI)model classified the isolates into three groups,which were different in origins and sympton types. A spot tyte isolate was distinguished from net type isolates by its generally high virulence. A slight pathogenic differentiation was suggested between Japanese and Canadian net type isolates.
Abstract Alternative 北海道およびカナダの春播オオムギがら採取した22の大麦網斑病菌株(Pyrenophora teres Drechs.)を世界各地のオオムギ38品種に幼苗接種し、病斑指数によって病原性の変異を検討した。分散分析の結果、菌株の病原力ならびに品種の抵抗性には有意差が認められたが、菌株と品種の交互作用は統計的には有意でなかった。各菌株の反応をFinlay-Wilkinson(1963)の回帰分析によって解析したところ、北海道とカナダの菌株で病原性反応に差が認められた。この傾向はカナダの菌株のうち、通常のNet typeの菌株よりも斑点状病斑を示すSpot typeの菌株で顕著であった(Fig.1)。さらに、菌株と品種の交互作用を詳細に解析するために相互作用と相乗交互作用モデル(AMMIモデル)を適用して交互作用に関する主成分分析を行った結果、各菌株は日本のNet type、カナダのNet type、カナダのSpot typeの3群に分けられた(Fig.1)。各菌株について群間ならびに群内の相関係数を算出したところ(Table5)、Net typeの菌株相互の相関係数は0.601~0.969と相対的に高かったが、一部の菌株と品種の組合わせでは抵抗性反応の逆転がみられた(Fig.4)。一方、Spot typeの菌株とNet typeの菌株の相関係数は0.302~0.538と低く、両者の病原性は多少異なることが示された。このような一部の菌株と品種の間に認められる弱い交互作用は、抵抗性を支配する主働遺伝子の特異的な反応が、いわゆる圃場抵抗性を支配する微働遺伝子の作用によって修飾された結果と考えられる。

Title Alternative 大麦網斑病抵抗性の選抜効果
FullText URL 003_001_043_053.pdf
Author Sato, Kazuhiro| Takeda, Kazuyoshi|
Abstract Selection effectiveness for the resistance to net blotch was estimated by using two sets of F2 and F3 populations derived from the crosses between resistant and susceptible parents. In every F2 and F3 population, disease ratings showed a continuous distribution. As many F3 lines with intermediate resistance had a smaller variance and homozygous genotype, the resistance might be controlled by a few genes. The heritabilities of the disease rating were estimated by correlation coefficients and regression coefficients between each F2 plant and the descended F3 lines. Another estimate for heritability was calculated by the selection differential in the F2 plants and genetic gain in the F3 lines. Despite the different level of resistance in the resistant parents of the two crosses, the three kinds of heritabilities estimated were similar and ranged from 0.6 to 0.8. Because of the fewer number of genes controlling the disease resistance and the higher heritabilities, selection in a early generation may be effective for net blotch resistance in barlcy.
Abstract Alternative 抵抗性と罹病性の両親間の交雑に由来する2組のF2集団とその後代のF3系統を用いて、大麦網斑病における抵抗性の選抜効果を推定した。F3系統の平均値と分散から、病斑指数の分散が小さく、すでに固定した系統が多数存在したので、抵抗性は少数の遺伝子に支配されているとみられた。F2個体とF3系統間の親子相関、親子回帰およびF2の選抜差とF3系統の遺伝獲得量から遺伝率を推定したところ、2組の交雑組合せで抵抗性親の病斑指数は異なっていたにもかかわらず、3種類の遺伝率の推定値はいずれも0.6~0.8の値を示した。遺伝率が高く、しかも関与する遺伝子数であるため、雑種集団で連続変異を示す場合の大麦網斑病抵抗性の選抜はF2からでも効果的とみられた。

Title Alternative Genetic Analysis of Large Trichome in Barley Leaf Blade
FullText URL 002_001_063_068.pdf
Author Sato, Kazuhiro| Takeda, Kazuyoshi|
Abstract The inheritance and linkage relationship of a new hairiness trait "large trichome" was investigated in barley. Although the size of large trichome is about four times that of normal one, the character can not be recognized with the naked eye. However, it is easily identified by the roughness of leaf touch. The large trichomes develop on both sides of the leaf blades. The direction of trichome is both acropetal and basipetal. It is clearly distinguished from the extremely long trichome controlled by Pub gene. About 2,300 varieties of our Barley Germplasm Center were screened by the leaf touch to find nine varieties with large trichome. Two of them were six-rowed local variety from Pakistan, and other seven were two-rowed varieties from Europe and Japan. All of them were hulled type. Crosses of six large trichome varieties with a normal Japanese variety resulted in the large trichome type F1s, suggesting the dominant nature of the trait. The large trichome line Hokuiku 17 was crossed with various linkage testres to study the mode of inheritance and the linkage relationship of the gene. In the F2 populations, the large trichome was controlled by a single dominant gene named Ltr (large trichome), which was independentiy inherited from the following marker genes; br and gl-5 on chromosome 1; li and ν on chromosome 2; uz on chromosome 3; K and gl-3 on chromosome 4; trd on chromosome 5; ο on chromosome 6. On the other hand, from the cross between Hokuiku 17 and OUL166, Ltr was found to be linked with s and fs on chromosome 7. Although the allelism test has not been completed, the very low frequency of the large trichome type (9/2,300) indicates that the variant resulted from a recent mutation event, or the fitness of the variant is low in the natural and/or artificial selection.
Abstract Alternative 岡山大学資源生物科学研究所大麦系統保存施設が保有するオオムギのうち約2,300品種を対象として、葉身の表面に生じる毛(trichome)の変異体を検索した。1)2,300品種のうち9品種(0.4%)が葉身の表面に剛毛を生じた。2)通常の品種では毛茸の鈎状部分の長さが約10μmであるのに対して剛毛型の品種では約40μmであった。Pub遺伝子による長毛はこれよりはるかに長く、剛毛型とは明らかに異なった。3)剛毛型は優性の1遺伝子(Ltr,large trichome)に支配されており、連鎖分析の結果、第7染色体にLtr-s-fsの順に配列されることが明らかになった。
