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.
The Yecoro wheat (right) cultivar is sensitive to salinity, plants resulting from a hybrid cross with cultivar W4910 (left) show greater tolerance to high salinity. Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. [1]
The breeder should also have definite goals with the choice of parents. Self-fertilizing are easier to maintain, but this could lead to misuse of seed. Some of the agronomy important, self-fertilizing crops include wheat, rice, barley, dry beans, soy beans, peanuts, tomatoes, etc.
A breeder reactor is a nuclear reactor that generates more fissile ... the U-233 content of the pellets was 5–6% in the seed region, 1.5–3% in the blanket region ...
Seed vigor is a measure of the quality of seed, and involves the viability of the seed, the germination percentage, germination rate, and the strength of the seedlings produced. [ 47 ] The germination percentage is simply the proportion of seeds that germinate from all seeds subject to the right conditions for growth.
A type of indehiscent fruit with the seed s immersed in the pulp, e.g. a tomato. bi-A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons.
A cultivar is a kind of cultivated plant that people have selected for desired traits and which retains those traits when propagated.Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production.
Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may have different characteristics from its parents. Some species produce seeds that require special conditions to germinate, such as cold treatment.
