Taschenbuch. Condition: Neu. Druck auf Anfrage Neuware - Printed after ordering - Presented here are modern and classical aspects ofcytogenetics as well as biotechnology in relation toimprovement of the Festuca-Lolium group of grasses. Festucaand its close relative Lolium are very valuable genera oftemperate agriculture. These fascinating genera containsome highly productive, nutritious, and well-adapted grasseswidely used for agricultural and recreational purposes worldwide.The book is organizedinto 15 chapters devoted to taxonomyand systematics; species evolution and divergence byincrease in chromosome number as well as by change in DNAcontent; genetic control of chromosome pairing and itsbreeding and phylogenetic implications; B chromosomes,induced polyploidy and haploidy inrelation to varietalimprovement; wide hybridization, genome relationships, andplant improvement; genomic balance in relation to hybridfertility and hererosis breeding; biotechnology and itspotential applications in plant improvement.It is of special interest to geneticists, taxonomists,evolutionists, biotechnologists, and plant breeders.…
