Parent Selection Flashcards
1
Q
Sources of parental germplasm
A
- Cultivars
- Elite breeding lines
- Breeding lines / germplasm release
- Transgenic plants (GMO)
- Plant introductions of cultivated species (PIs)
- Related species and [sometimes] genera
2
Q
Qualitative inheritance
A
At least ONE parent must have desired trait.
3
Q
Quantitative inheritance
A
Transgressive segregation… perform better than parents -> outliers.
4
Q
Improvement implies…
A
population development through parent selection.
5
Q
When setting goals, make sure they are…
A
** achievable!
5 traits would be extremely difficult…
- ex. 1/4 x 1/8 x 1/20 x 1/60 x 1/100 = 1/3.84 million lines!
2 traits is more reasonable…
- ex. 1/4 x 1/8 = 32 lines!
