For resistance sources BGM0284 and BGM1370 in
Group 1, combinations of crosses with a lower kinship degree were found among varieties in Group 3 (Table
4). For the BGM0281 accession, the two most contrasting
genotype combinations were those with the BRS
Mulatinha (-0.109) and BRS Tapioqueira (-0.094) varieties,
both belonging to Group 2. However, for the source
BGM0284, the lowest kinship estimates were obtained
with the Cidade Rica (-0.267) and Lagoa (-0.283) varieties,
and for the source BGM1370, the best combinations
were with the Baianinha (-0.202) and Lagoa (-0.168) varieties.
Even with a median kinship degree, the resistance
sources BGM0281 and BGM0284 showed a lower
relatedness degree with different varieties, which can
certainly help to increase the genetic variability in the
populations carrying this highly divergent genetic background.
