The existence of limits in artificial selection experiments was discussed in the scientific literature in the 1940s or earlier. [1] The most obvious possible cause of reaching a limit (or plateau) when a population is under continued directional selection is that all of the additive-genetic variation (see additive genetic effects) related to that trait gets "used up" or fixed. [2]
Watermelon is a sweet, commonly consumed fruit of summer, usually as fresh slices, diced in mixed fruit salads, or as juice. [53] [54] Watermelon juice can be blended with other fruit juices or made into wine. [55] The seeds have a nutty flavor and can be dried and roasted, or ground into flour. [9]
In mass selection there are some factors that must be considered when selecting plants in a mother block, e.g. vineyard. Time of selection is a big factor, because you have to select when most of the characteristics of the plant are clearly showing. With asexual perennials the best time is just before harvest.
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Plant breeders' rights (PBR), also known as plant variety rights (PVR), are rights granted in certain places to the breeder of a new variety of plant that give the breeder exclusive control over the propagating material (including seed, cuttings, divisions, tissue culture) and harvested material (cut flowers, fruit, foliage) of a new variety for a number of years.
Selective breeding of plants and animals has led to varieties that differ dramatically from their original wild-type ancestors. Examples are the cabbage varieties, maize, or the large number of different dog breeds. The power of human breeding to create varieties with extreme differences from a single species was already recognized by Charles ...
Chen Wen-yu (Chinese: 陳文郁; 20 November 1925 – 7 December 2012) was a Taiwanese botanist, horticulturist and an inventor in agriculture science.He bred new strains and varieties of plants, including fruits, flowers, and vegetables over his 70-year-long career.
Selective breeding of rare breeds and rare pedigrees, particularly monitoring breeding genetics in small populations to ensure diversity is maintained as much as possible; [2] Rare breeds that suffer life-threatening genetic deficiencies can be intentionally cross-bred with other breeds that have the critical gene, in order to preserve the rare ...
