F) The resistant varieties to the late blight.
1) Introduction
I am interested for a long time in the varieties of resistant potatoes to the late blight (Phytophthora infestans).
In 2014, I sowed two tomatoes resistant varieties to the late blight:
A) Defiant F1 and F2
B) Plum Regal F1.
As I had already noticed the power of blue danger, I had crashed outside both resistant varieties in the presence of plants of blue tomatoes.
I hoped that bumblebees were going to realize hybridizations:
a) By transporting some pollen with the genes of resistances towards the flowers of varieties of blue tomatoes.
b) By transporting the blue genes towards the flowers of resistant varieties.
It is the genes ph2 and ph3 that give the resistant to the varieties.
Ph3 must be present and Ph2 strengthens Ph3 if he is present.
Ph2 only give a lesser resistance.
Defiant F1 and Plum regal F1 have both genes.
I got back all the seeds of the tomatoes of the resistant varieties.
I calculate every time the number of days when the tomato remained in the plant by making the subtraction of:
( In the daytime of harvest - day of plantation)
And I indicate it in the following way:
300DZ ( Defiant F1)--> 4604AB (AB Defiant F2 R103) 3003NT ( Defiant F2)-->4785AB (AB Defiant F3 R76)
DZ and NT is a member both of Tomatoville.
2) 2014 Tomatoes Defiant F3
Here are examples of obtained tomatoes:

AB is both initials indicating me:AmBiorix
I place these two initials behind the number of the year for the reference of seeds.
And I place AB in front of the variety and the generation of the variety follow-up of the number of days since the plantation until the harvest. (AB to show that the crossing was can - be made by bumblebees at AB)
XT284a indicates that the plant is outside (XT), that the plant has the number 284 and a if it is the first harvested tomato.
3) 2015 Tomatoes Defiant F4
3003NT (Defiant F2)-->4785AB (AB Defiant F3 R76)--> 5830AB (AB Defiant F4 R89)
5830AB was harvested in big greenhouse because this plant had been let there to study well its evolution.
Sowing 102 location GD72 (Place which receives the sun since the sunrise till 6:00 pm).
