Marker Assisted Breeding • 372 seedlings of M597 (Evereste x G.C.202) screened for Fire Blight resistance genes from Evereste (R_E) and from Robusta 5 (R_R5) through G.C.202 in 2016 Phenotypic screening for Woolly Apple Aphid (WAA) Resistance linked to Robusta 5 and Evereste genes Resistance linked to Robusta 5 gene Resistance linked to Evereste gene Susceptible
Marker Assisted Breeding WAA resistance evaluated through inoculation • in September 2016. In total 235 seedlings were scored: – 74 were found to be resistance – 161 developed colonies • SSR markers selection associated to resistance gene from Robusta 5 (Er2), two PCR multiplexes defined (WAA_MP_A and WAA_MP_B) – on-going optimization and screening of M597 – Marker CH04f08 discarded for this family, same allele patter in both G.C.202 and Evereste WAA_MP_A WAA_MP_B Marker Allele range Marker Allele range GD153 180-150 CH04c10 125-179 CH04c06 155-200 CH02g04 174-207 NH015a 98-169 SAmsCO963298 345-390 NZmsEE669355 175-200 NZmsMSAj1681 169-201 CH01h01 114-134 SAmsEE663640 476-485 SAmsCV150384 230-250 GD96 140-180 CH04f08 180-200 GD112 200-240 Hi01d06 95-165 NSmsEB145764 180-215 AT00174 180-210
