STEP 3: Select the best. There are 4 types of trees to choose from in the last generation: T T High sugar high quality types not GE ECF + High sugar types ECF not desirable sugar and/or fruit type Not desirable sugar and/or fruit type not GE Only the high sugar, high quality, non-ECF (non-GE) types are selected.

Outcome: ‘FasTrack’ Breeding as outlined in this presentation can, in a relatively short time, provide improved tree fruits (in this case high quality, high sugar plums). For example, considering a generation time of 4 years for plum, 3 generations would normally require 16 years. FasTrack breeding would accomplish 3 generations in 5 years! In the end the selected FasTrack bred trees are not genetically engineered. Each tree has the potential to be a new cultivar or an improved type that can be used for continued breeding through conventional means.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
