Things to note: i)
F1 is highly resistant, DSI = 0.5. ii) Fruit
shape, round is dominant. iii) green shoulder is present in hybrid, g+/g.
iv) size is intermediate between the two parents. If the cross was made between G13h and a susceptible line, the DSI would be about 2 for the F1. If G171c crossed with a susceptible line, it is expected the DSI would be 3 to 3.5 for the F1. |
