| 内容記述 | [Author abstract]A commercial dikaryotic stock Ns92-4 of Flammulina velutipes is characterized by the mating type A4B4+A5B5, producing plentiful fruit-bodies. From a single fruit-body of this stock fifty-five monokaryotic progenies were isolated by plating basidiospores. They were subjected to the examination of mating type by test-cross to the mating type testers, then twenty-two of them exhibiting monkaryotic fruiting were chosen randomly and mycelial growth rate and the dry weight productivity of mycerium were determined. The progenies having A5 factor proved to recover sporadically and showed slow mycelial growth, suggesting that the A5 would tightly link to a gene a^<rep> expressing slow mycerial growth to drop viability.The monokaryotic progenies were crossed between in every possible compatible combinations, and resulted in ninety-two synthetic dikaryotic stocks followed by determination of mycelial growth rate and mycelial productivity. As the result, strong correlations were found between: mycelial growth rate and mycelial productivity of dikaryotic stocks (inverse),mid-parents and dikaryotic stocks of mycelial growth rate (inverse),mycelial growth rate of mid-parents and mycelial productivity of dikaryotic stocks (inverse),andmid-parents and dikaryotic stocks of mycerial productivity (direct).However, it was obvious in every scatter diagrams that two separate groups of dikaryotic stocks existed: the group 1 in a corner of slow growth and copious productivity, and the group 2 in quick and poor. Such diagonal location of two groups in the diagrams arose apparent and strong correlations, although nothing was detected within each group.Analysis of genetical nature of the stocks of the group 1 may have significance for the breeding of this fungus, since the amount of mycelia established has been found to be prerequisite for further plentiful friuiting (LI and KINUGAWA 1981). By tracing the origin of constituent monokaryons, every stocks of the group 1 proved to be synthesized by crossing within monokaryons of a specific class, and the stocks of the groups 2 by crossing any of the specific class with any compatible one of the remainders or by crossing within the remainders.When assuming a recessive gene f, expressing slow mycelial growth and copious mycelial productivity in homozygous condition, the dikaryotic stocks of the group 1 may have f+f and those of the group 2 f+ F or F+ F, in genic constitution.The gene f may differ from another gene a^<rep> which links to the A5, since the distribution of the gene was independent to those of A5 among the monokaryons.[著者抄録]エノキタケの商業品種NS92-4は交配型A4B4+A5B5の複核株である。この菌株から担子胞子をとり単個培養して単核系統群を得た。交配型因子の分離をしらべると、A因子の分離に異常があり、A5を含む単核系統は菌体乾量に偏りはないが、菌糸体生長速度が小さく、A4を含むものにくらべて少数しか分離できなかった。因子A5は、菌糸体生産量に影響しないが生長を抑制する遺伝子(a^<rep>)と強く連鎖しているもようである。単核系統をすべての可能な組合せで群内交配して、複核株 92株を作出し、単核系統群と同じく菌糸体生長速度と菌糸体生産量を測定した。交配親である2つの単核系統の測定値の平均を中間親とし、中間親群と複核株群の諸測定値の比較をするとつぎの通りである。複核株では菌糸体生長速度と菌糸体生産量の間に負の相関が、中間親と複核株の間には菌糸体生長速度と菌糸体生産量のそれぞれにおいて正の相関があり、菌糸体生産量については中間親と複核株の間に負の相関があった。しかし、各量の散布図を観察すると、複核株群には、(1)菌糸体生長速度が小さく菌糸体生産量の大きい群と(2)その逆の特徴をもつ群がプロットされ,全体としての相関は(1)と(2)の相対的位置によって生じていた。そして、(1)は特定の単核系統間の交配でのみ作出され、他の単核系統間または特定の単核系統と他の系統との間の交配からは(2)の複核株が生じていた。 | |||||||||||||
