ABSTRACTSeed Purity Testing of F3 Progeny of Rice Lines Derived from a Cross between Pandanwangi x PTB-33 Estimated by Simple Sequence Repeat MarkersSeeds with high purity is required to produce maximum crop yield. Genetic purity of selected F3rice seed progenies derived from a cross between Pandanwangi x PTB33 was estimated by SSR(simple sequence repeats) molecular markers. Objective of current experiment was to obtain riceseed with high genetic purity (100%) in terms of homogeneity of alleles. The experiment wasconducted at Laboratory of Plant Analysis and Biotechnology, meanwhile field experiment wasperformed at Ciparanje Experimental Station, Faculty of Agriculture, Universitas Padjadjaran.Based on primer designed by Bradbury (aromatic trait) and primers RM589 and RM586 (supposedto correlate with brown planthopper resistance gene), seeds of F3 selected had 100% geneticpurity. SSR markers applied for each offspring were able to demonstrate the purity of the seed.Genotypes with 100% genetic purity can be continued for propagating their seeds.Keywords: F3, seed purity, seed rice, SSR markersABSTRAKBenih dengan kemurnian genetik tinggi sangat diperlukan untuk produksi tanaman yangmaksimal. Kemurnian genetik padi generasi F3 hasil persilangan Pandanwangi x PTB-33 diestimasidengan menggunakan marka molekuler SSR. Percobaan ini bertujuan untuk mendapatkan generasiF3 yang memiliki kemurnian genetik 100%. Penelitian dilaksanakan di Kebun PercobaanCiparanje, Fakultas Pertanian Universitas Padjadjaran dan Laboratorium Analisis dan BioteknologiTanaman. Hasil analisis menggunakan primer Bradbury menunjukkan 100% benih murniberdasarkan karakter aromatik, begitupun berdasarkan karakter ketahanan terhadap wereng(primer RM589 dan RM586) menunjukkan 100% benih murni. Marka molekuler SSR yangdigunakan untuk verifikasi kemurnian mampu menunjukkan kemurnian genetik benih padi yangtinggi. Genotip PP dapat dilanjutkan untuk pengujian dan atau perbanyakan benih sumber.Kata kunci: benih padi, F3, marka SSR, uji kemurnian genetik

Dominant Genes

<p>Resistance traits to brown planthopper on rice varieties are controlled by dominant and recessive genes called Bph/bph. Bph17 is one of dominant genes that control rice resistance to brown planthopper.  Marker of Bph17 allele can be used as a tool of marker assisted selection (MAS) in breeding activity. Association of Bph17 allele and resistance to brown planthopper in Indonesian landraces and new-improved varieties of rice is not clearly known. The study aimed to determine the association of Bph17 allele in landraces and new-improved varieties of rice resistant to brown planthopper. Twenty-one rice genotypes were used in the study, consisting of 13 landraces, 5 improved varieties, 3 popular varieties and a check variety Rathu Heenati. Two simple sequence repeat markers linked to Bph17 allele were used, i.e. RM8213 and RM5953. The results showed that association of Bph17 allele in landraces and new-improved varieties of rice resistant to brown planthopper resistance was very low (r = -0.019 and -0.023, respectively). The presence of Bph17 allele did not constantly express resistance to brown planthopper. The study suggests that Bph17 allele cannot be used as a tool of MAS for evaluating resistance of landraces and new-improved varieties of rice to brown planthopper. Further research is needed to obtain a specific gene marker that can be used as a tool of MAS and applicable for Indonesian differential rice varieties. </p>
