dc.descriptionAgronomic Characters and Resistance of Several Dihaploid Maintainer Lines to Bacterial Leaf Blight. Bacterial blight (Xanthomonas oryzae pv. oryzae, Xoo) is one of the most serious diseases of rice in Indonesia. From previous research thirteen lines of dihaploid (DH) maintainer lines-derived anther culture were selected for developing cytoplasmic male sterile lines. In this research those DH maintainers were evaluated for their agronomic characters such as plant height, number of productive tiller, and seed weight per hill as well as their resistance to Bacterial Leaf Blight (BLB) pathotypes III, IV and VIII at Indonesian Center Rice Research (ICRR), Sukamandi during wet season 2008/2009. The results showed that 10 DH maintainer lines i.e. BioMAc18-H36-3-Ma, BioMAc19-H36-3-Mb, BioMAc20- H36-3-Mc, BioMAc21-H36-4-M, BioMAc26-B1-1-Mb, BioMAc29-B2-1-Db, BioMAc31-B2-1-M, BioMAc33-B2-4- Pb, BioMAc34-B4-1-Da and BioMAc35-B4-1-Dc having plant height ranged from 88.79-104.08 cm, productive tiller ranged from 9 to 13 tillers/hill. Among those DH maintainer lines three lines were resistant to BLB pathotype III, i.e. BioMAc26-B1-1-Mb, BioMAc29-B2-1-Db and BioMAc31- B2-1-M lines, and two lines, i.e. BioMAc21-H36-4-M and BioMAc35-B4-1-Dc were highly resistant to BLB pathotype VIII. Only BioMAc35-B4-1-Dc lines highly resistant to BLB pathotype IV. AbstrakHawar daun bakteri yang disebabkan oleh bakteri Xanthomonas oryzae pv. oryzae, (Xoo) adalah salah satu penyakit utama padi di Indonesia. Dari penelitian sebelumnya 13 galur pelestari dihaploid (DH pelestari) yang berasal dari kultur antera telah diseleksi untuk perakitan galur mandul jantan baru. Tujuan penelitian ini adalah untuk mengevaluasi karakter agronomi dan ketahanan galur-galur DH pelestari terhadap patogen HDB. Karakter agronomi yang diamati meliputi tinggi tanaman, jumlah anakan produktif, dan bobot hasil per rumpun, sedangkan ketahanan terhadap HDB diamati berdasarkan skor ketahanan terhadap Xoo patotipe III, IV dan VIII di Balai Penelitian Padi, Sukamandi pada musim hujan 2008/2009. Hasil penelitian menunjukkan 10 galur DH pelestari, yaitu galur BioMAc18-H36-3-Ma, BioMAc19-H36-3-Mb, BioMAc20- H36-3-Mc, BioMAc21-H36-4-M, BioMAc26-B1-1-Mb, BioMAc29-B2-1-Db, BioMAc31-B2-1-M, BioMAc33-B2-4- Pb, BioMAc34-B4-1-Da, dan BioMAc35-B4-1-Dc mempunyai tinggi tanaman berkisar antara 88,79-104,08 cm, anakan produktif berkisar antara 9-13 batang/rumpun. Di antara galur DH pelestari yang tahan terhadap HDB patotipe III, yaitu galur BioMAc26-B1-1-Mb, BioMAc29-B2-1-Db dan BioMAc31- B2-1-M, dua galur yaitu galur BioMAc21-H36-4-M dan BioMAc35-B4-1-Dc sangat tahan terhadap HDB patotipe VIII, sedangkan galur BioMAc35-B4-1-Dc yang sangat tahan terhadap HDB patotipe IV.en-US
