NEBR goes as far as saying that "movement out of the agricultural sector has been responsible for growth and poverty reduction in Africa."
This is because the services sector in Sub-Saharan Africa is unlikely to be an engine of sustained productivity growth over the long run," NEBR warned.
Race 51 was chosen because in our preliminary screening of SR to several races of the rust pathogen, Olathe was resistant to race 51, whereas Nebr.#1 sel.27 was susceptible.
The 680 primers were used to simultaneously screen between the two different DNA bulks from resistant and susceptible [F.sub.2] plants, and between the parents Olathe and GN Nebr.#1 sel.27.
The specific forward and reverse 24-mcr primer pair was tested in the [F.sub.2] population of the cross Olathe and Nebr.#1 sel.27.
Because of the dominant character of RAPD and SCAR markers, the linkage analysis of seven coupling- or five repulsion-phase markers with the Ur-6 locus for SR to rust was separately performed on the data for 100 [F.sub.2] plants of the cross Olathe x Nebr.#1 sel.27 by MAPMAKER version 3.0 (Lander et al., 1987).
Clear separation for the disease rating of the parents Olathe and GN Nebr.#1 sel.27 to race 51 of the bean rust pathogen was observed in the greenhouse test.
Eighty-nine [F.sub.2] plants and 78 [F.sub.3] families (12-16 plants per [F.sub.3]) with the parents GN1140 and Nebr. #1, 33 MA or Andean bean cultivars-lines, and 78 RILs with their parents BelNebRR-1 and A 55 were planted in the greenhouse.
Race 59 was chosen because in our preliminary screening of SR to races GN1140 was resistant to race 59, whereas Nebr. #1 was susceptible.
The 280 primers were used to simultaneously screen between the two different bulked DNAs from resistant and susceptible [F.sub.2] plants, and between the parents GN1140 and Nebr.#1.
Because of the dominant character of RAPD markers, the linkage analysis of six coupling- or three repulsion-phase RAPD markers with the Ur-7 locus for SR to rust was separately performed on the data for 89 [F.sub.2] plants of the cross GN1140 x Nebr. #1 with MAPMAKER version 3.0 (Lander et al., 1987).
Clear separation for the disease rating of the parents GN1140 and Nebr. #1 to rust race 59 was observed in the greenhouse test.
