| বিবরন: | The inheritance of host to stunt maize was studiedunder natural field conditions. Inbred lines P1 (moderatelyresistant) and P2 (susceptible) and their F1, F2, [BC(P1) andBC(P2)] progenies were evaluated at two seasons at sea level,in Veracruz in 1999. Significant epistatic effects were notedto the resistance to stunt corn; however, the dominantgenetics effects were greater and more important thanadditive and epistatic effects. The data showed that resistanceto stunt corn was controlled by only a few major genes. TheF1 hybrid showed high tolerance, indicating dominance andmid-parent heterosis for resistance was also observed. Thedata indicate that a back-crossing procedure can be used totransfer the resistance factors into elite lines. Some form ofrecurrent selection in populations having a degree ofresistance also is suggested. |
