Plant breeding , application of genetic principles to produce plants that are more useful to humans. This is accomplished by selecting plants found to be economically or aesthetically desirable, first by controlling the mating of selected individuals, and then by selecting certain individuals among the progeny.


Principles of Plant Genetics and Breeding, 2 nd Edition introduces both classical and molecular tools for plant breeding. Outline the procedure for transfer of a dominant resistance gene through Backcross method. All chapters begin with a brief summary followed by text with suitable examples. Outline the procedure for transfer of a recessive resistance gene through Backcross method. Highly recommended! Science Cultivating Practice is an institutional history of agricultural science in the Netherlands and its overseas territories. Haploid plants have the gametophytic number of chromosomes.

Katarina Borojevic, Principles of Plant Breeding, 2nd ed. The first edition of Principles of Plant Breeding , by R. Allard, professor of genetics and of agronomy and range science, was a book used worldwide as a university textbook as well as a guide for plant breeders. In this second edition, the author has edited the book, including additional data about the evolution of plant populations during domestication and cultivation; these evolutionary changes play an important role in understanding the principles and methods of plant breeding and improvement. The author devotes the first two chapters of the book to the central ideas of Charles Darwin's Origin of Species , to the Darwinian evolutionary changes which occur during cultivation, and to the origins of agriculture. In the third chapter, he describes evolution during domestication, discussing when the first selection pressure was applied to wild plants and what brings them to cultivation.

Since modern methods of plant breeding involving oligonucleotide-directed mutagenesis ODMs or site-directed nucleases SDNs , including Clustered Regularly Interspaced Short Palindromic Repeats CRISPR , are becoming ever more popular, it is crucial to establish whether the products of such new breeding techniques NBTs , in particular those which involve precise methods of mutagenesis, … phenotype. Definition: Plant breeding is an art and science which deals with changing genotypes of the plants, to adapt them to the service of human being. However, the current plant breeding methods are entirely based on scientific principles of plant sciences. Nutrient use efficiency particularly nitrogen and phosphorus Weed competitiveness.

Conventional plant breeding is the development or improvement of cultivars using conservative tools for manipulating plant genome within the natural genetic boundaries of the species. Mendel's work in genetics ushered in the scientific age of plant breeding. The number of genes that control the trait of interest is important to breeders. Qualitative traits controlled by one or a few genes are easier to breed than quantitative traits controlled by numerous genes. Breeders use methods and techniques that are based on the mode of reproduction of the species self-pollinating, cross-pollinating, or clonally propagated. The general strategy is to breed a cultivar whose genetic purity and productivity can be sustained by its natural mating system. There are six basic types of cultivars: pure line, open-pollinated, hybrid, clonal, apomictic and multilines.

Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. The most frequently addressed traits are those related to biotic and abiotic stress tolerance, grain or biomass yield, end-use quality characteristics such as taste or the concentrations of specific biological molecules proteins, sugars, lipids, vitamins, fibers and ease of processing harvesting, milling, baking, malting, blending, etc. Genes in a plant are what determine what type of qualitative or quantitative traits it will have. Plant breeders strive to create a specific outcome of plants and potentially new plant varieties. It is practiced worldwide by individuals such as gardeners and farmers, and by professional plant breeders employed by organizations such as government institutions, universities, crop-specific industry associations or research centers. International development agencies believe that breeding new crops is important for ensuring food security by developing new varieties that are higher yielding, disease resistant, drought tolerant or regionally adapted to different environments and growing conditions. Plant breeding started with sedentary agriculture and particularly the domestication of the first agricultural plants, a practice which is estimated to date back 9, to 11, years.

Мидж повернулась на вращающемся стуле. - Такой список выдает только принтер Фонтейна. Ты это отлично знаешь. - Но такие сведения секретны. - У нас чрезвычайная ситуация, и мне нужен этот список. Бринкерхофф положил руки ей на плечи.

Мы говорим о математике, а не об истории. Соши замолчала. - Полезный груз? - предложил Бринкерхофф.  - Количество жертв. Ущерб в долларах. - Нам нужна точная цифра, - напомнила Сьюзан.  - Оценки ущерба всюду приводятся разные.

Мысли ее смешались. Хоть бы замолчала эта омерзительная сирена. Почему Стратмор отмел такую возможность. Хейл извивался на полу, стараясь увидеть, чем занята Сьюзан. - Что .

Коммандер, недовольный необходимостью говорить по линии, не защищенной от прослушивания, попросил Дэвида не звонить, пока кольцо не окажется в его руках. Он решил было обратиться в полицию - может быть, у них есть данные о рыжеволосых проститутках, - но Стратмор на этот счет выразился недвусмысленно: Вы должны оставаться невидимым. Никто не должен знать о существовании кольца. Может быть, стоит побродить по Триане, кварталу развлечений, и поискать там эту рыжую девицу. Или же обойти все рестораны - вдруг этот тучный немец окажется. Но и то и другое вряд ли к чему-то приведет.

 О да, конечно, - медленно проговорила женщина, готовая прийти на помощь потенциальному клиенту.  - Вам нужна сопровождающая. - Да-да. Сегодня мой брат Клаус нанял девушку, очень красивую. С рыжими волосами. Я тоже хочу.
