| 31. Identification of RAPD marker linked to the gene controlling gall midge resistance against all biotypes in China (1031 words) |
 | An F`3` mapping population was prepared from a cross between Duokang # 1 (gall midge resistant) and Feng Ying Zhan # 1 (susceptible) and 160 lines were phenotyped for all midge resistance at Guanzho Acad. |
 | Phenotypic testing of 160 F3 families from the cross between Duokang#1 X Feng Ying Zhan #1 _______________________________________________________________________________ Group Plants infested No. of F`3` families in a family _______________________________________________________________________________ 1. |
 | DNA (2ug) from each of 12 lines with phenotypic score 0 and from each of 12 lines with phenotypic score 100 were pooled to make the resistant and susceptible bulks, respectively. |
