Hybrid seeds planted by the farmer produce similar plants, but the seeds of the next generation from those hybrids will not consistently have the desired characteristics because of genetic assortment. It is therefore rarely desirable to save the seeds from hybrid plants to start the next crop.
A genetically modified tomato, or transgenic tomato, is a tomato that has had its genes modified, using genetic engineering. The first trial genetically modified food was a tomato engineered to have a longer shelf life (the Flavr Savr ), which was on the market briefly beginning on May 21, 1994. [ 1 ]
The root growth of C22 exceeded that of C0 and the ratio of shoot dry mass to root dry mass was reduced by nearly 12%, from 8.0±0.2 to 7.1±0.1 (Table 2). Analysis of yield components revealed that C22 was superior to C0 in grain weight, number of rows per ear, number of grains per row, and total yield per unit area (Table 3).
Crops such as maize reproduce sexually each year. This randomizes which genes get propagated to the next generation, meaning that desirable traits can be lost. To maintain a high-quality crop, some farmers purchase seeds every year. Typically, the seed company maintains two inbred varieties and crosses them into a hybrid strain
The "Better Boy" tomato variety is a hybrid between the Teddy Jones heirloom tomato variety and an unknown red variety developed by plant breeder John Peto. [1] Better Boy fruit grows from an indeterminate plant, growing to about 340 grams (12 oz) in weight, and typically ripens in around 72 days, growing to about 150 centimetres (5 ft) high. [ 2 ]
Tomatoes contain seeds and are therefore a fruit. Technically, the part of the plant that bears seeds for reproduction is a fruit. The other parts of the plant, like the root, leaves and stems are ...
Celebrity tomato plant requires full sun to grow and reach its potential height, bear fruits and achieve maximum yields. [5] Although Celebrity tomatoes can be grown in a wide range of soils it is recommended to plant them in loosely packed and nutrient-rich soils. Seeds are typically sown 6-8 weeks before the last frost date. [9]
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]
