Title StatementResistance of abaca (Musa textilis Nee) F1 hybrids to abaca bunchy-top virus. Norman T. Diaz
Physical Descriptiona73 leaves3
Summary, Etc.aThis study was conducted to generate F1 hybrids of Mininonga crossed with six varieties of abaca through conventional methods, and screen the hybrids for resistance to abaca bunchy-top. Of the different crosses made, only the following crosses produced F1 seedlings: Malaniceron x Mininonga, Sogmad Pula x Mininonga, Mininonga x Itolaus 39, Mininonga x Layahon, Mininonga x Tinawagan Puti, Tinawagan Puti x Mininonga and Mininonga x Putumag 22. The reaction to bunchy-top of these hybrids varied. Malaniceron x Mininonga and Sogmad Pula x Mininonga crosses were resistant and moderately resistant, respectively. On the other hand, the Mininonga x Itolaus 39 and Mininonga x Layahon crosses yielded resistant hybrids. Moderately resistant reaction was observed on the Mininonga x Tinawagan Puti, Tinawagan Puti x Mininonga and Mininonga x Putumag 22 hybrids. Generally, the cross of a susceptible variety to a moderately resistant or resistant cultivar produced resistant hybrids. Moderately resistant reaction was observed on a cross of susceptible variety to a moderately susceptible one. This study identified resistant and moderately resistant hybrids to abaca bunchy-top. If the results of this study were to benefit the abaca industry, the abaca farmers and Philippine agriculture in general, this study must be pursued to its final end. These hybrids can also be used as genetic stocks in future breeding work. Moreover, this study can be expanded to include other collections in existing abaca germplasm with varying degree of resistance to abaca bunchy-top to confirm the results obtained in this investigation. FIDA, on the other hand, must extend adequate and sustained financial and manpower support on further researches in abaca bunchy-top and other major diseases of abaca to fully address the problem of controlling them.0
