Cross Type

Use the drop-down menu to specify the experimental crossing type.

Note : As this parameter is used in multiple processes, actual options might vary.

Cross types are described in the following table:

Cross Type	Description
BC1	Backcross of the F1 lines to P1 (data should be AA and AB genotypes ).
BC2	Backcross of the F2 lines to P2 (data should be AB and BB genotypes).
F2	F2 intercross of two F1 lines generated by homozygous parental lines P1 and P2.
RILself or RI1	Selfing to generate recombinant inbred lines.
RILsib	Sibling pair mating to produce recombinant inbred lines.
DH or RI0	Generation of a doubled-haploid line.
AIL or SFn	Selfing on an inbred line followed by random mating over n -1 generations.
IRILself	Intercrossed recombinant inbred line formed by n generations of random mating prior to selfing.
B1n	Backcross design F1xP1, where n is the Genotyping Generation (the number of backcrosses to P1).
B2n	Backcross design F1xP2, where n is the Genotyping Generation (the number of backcrosses to P2).
RI2	Recombinant inbred via random mating.
RFn	Randomly mated generation n -times intercrossed.
T(B1)SFn	Testcross of SFn to P1.
T(B2)SFn	Testcross of SFn to P2.
T(B1)RFn	Testcross of RFn to P1
T(B2)RFn	Testcross of RFn to P2
T(SFm)SFn	Testcross of SFn for m generations.
