Selfed plants
WebScience Biology Two true-breeding pea plants are crossed: one has purple flowers and green seeds, and the other has white flowers and yellow seeds. The F1 progeny are selfed to get F2 plants. Purple flowers and yellow seeds are dominant. What is the probability that the first three F2 plants all have purple flowers and yellow seeds? WebThe farmer has two berry plants. When selfed, the first plant produces tall, thorned plants with a mixture of axial and terminal flowers. The other plant produces a mixture of tall and short plants, which are all thornless and have terminal flowers.

WebFeb 16, 2024 · Selfed plants produced significantly smaller flowers that lived for a significantly shorter amount of time than flowers of outcrossed plants, based on corolla and stigma longevity. Consistent with prior work, we found trade-offs between floral longevity and flower number and positive relationships between longevity and plant height. WebIn self pollinated crops, a mass selected variety is homozygous but heterogeneous, because it is a mixture of several pure-lines. In cross pollinated crops, such varieties are mixture of homo and heterozygotes and are heterogeneous, because they consist of several homo and heterozygous genotypes. 3. Adaptation:

WebNov 10, 2024 · Plant breeders generally assemble germplasm, evaluate selected selfed plants, cross the progenies of the selected selfed plants in all possible combinations and bulk and develop inbred lines from the populations. In cross-pollinated crops, a cyclical selection approach, called recurrent selection, is often used for inter-mating. The cyclical ...
