Abstract

Improved rice varieties play an important role in increasing rice production, through raising and/or stabilizing rice productivity.  Thus, it is urgent to develop improved rice varieties.  Selection method is an important step in rice improvement.  Implementation of recurrent selection in rice improvement was aimed to increase the efficiency and insurance in the success of improvement.  Since 2004, Indonesian Institute for Rice Research has applied recurrent selection in breeding program. Promising lines of earliness and high yield potential were developed in relatively short time.  A number of advanced lines has been produced and will be further evaluated, and a number of populations has been selected and used as base populations for recurrent selection in rice improvement program.   Key words:  breeding, earliness, high yield rice, improvement

Abstract

The breeding of upland rice with New Plant Type characters in relatively short time can be done by using anther culture technique. The technique has been recognized as a rapid and efficient technology for crop improvement. Plant materials used in this research were F1 crossing P1 (Fatmawati x Way Rarem), P2 (Fatmawati x SGJT-28),  P3 (Fatmawati x SGJT-36), P4  (Way Rarem x Fatmawati), P5 (SGJT-28 x Fatmawati), and P6  (SGJT-36 x Fatmawati). Media for calli induction (N6) and regeneration (MS) were according to Dewi methods (2003). The results of this study indicated that P3 (Fatmawati x SGJT-36) and P6 (SGJT-36 x Fatmawati)  from resiprocal crosses gave better response in anther culture than the others crosses for their calli induction and green plant regeneration. From the six F1 crosses, 348 (53.5%) spontaneous doubled haploid (DH) pure lines were obtained, six lines from Farmawati x Way Rarem, 13 lines from Fatmawati x SGJT-28, 187 lines from Fatmawati x SGJT-36, three lines from Way Rarem x Fatmawati, five lines from SGJT-28 x Fatmawati, and 134 lines from SGJT-36 x Fatmawati.  These lines should be evaluated and characterized for their agronomical and morphological  traits.    Key words: Anther culture, doubled haploid, callus induction, green plant regeneration

Abstract

F1 Hybrids, backcross progenies, advanced introgression lines (2n=24) and monosomic alien addition lines or MAALs (2n=25) were successfully produced following embryo rescue between an elite new plant type (NPT) breeding line of Oryza sativa (2n=24, AA) and a wild species, O. minuta (2n=48, BBCC). F1 hybrids performance were intermediate between the parents. The F1 hybrids had 36 chromosomes indicating having 12 chromosome A from O. sativa and 12 B and 12 C from O. minuta. THE BACK CROSS progenies had different chromosome number indicating abnormal meiosis of the hybrids and back cross progenies. Plant with 2n=24 and 25 chromosomes were obtained in BC4FI. The hybrids and backcross progenies were susceptible to bacterial leaf blight (BB). However, several of the 2n=24 plants derived resistant plant to bacterial leaf blight race 1 of the Philippines races. The gene is different from introgressed gene intio rice from O. longistaminata ( Xa21) and from O. Minuta Acc. 101141   I Key words: Oryza minuta, MAALS, Bacterial leaf blight

Abstract

Beras (Oryza sativa L.) merupakan bahan makan penduduk Indonesia sebagai sumber energi, protein, lemak, vitamin dan zat-zat lain yang mempunyai fungsi fisiologis yang berpengaruh dalam pertumbuhan, perkembangan dan kesehatan manusia. Beras aromatik, beras merah dan ketan merah mempunyai nilai tambah dibanding dengan putih sehingga harganya lebih tinggi. Yogyakarta adalah kota budaya, wisata dan kota pendidikan sehingga membutuhkan beras tersebut. Pemilikan lahan petani Yogyakarta sempit, maka dengan menanam padi yang mempunyai nilai tambah akan dapat meningkatkan pendapatan petani baik dari peningkatan produktivitas maupun dari harga jual yang tinggi. Hasil uji adaptasi tiga galur harapan padi aromatik, dua galur beras merah, satu galur ketan merah dan dua galur potensi hasil tinggi di 3 lokasi dalam dua musim pada tahun 2009 dan 2010 menunjukkan bahwa keragaan dan hasil galur/varietas yang diuji bervariasi. Variasi hasil galur/varietas dipengaruhi oleh lokasi dan musim tanam.  Galur padi aromatik B11955-MR-84-1-4 mempunyai hasil GKG sepuluh persen lebih tinggi dibanding varietas padi aromatik Sintanur. Galur beras merah B11844-MR-7-17-3 mempunyai hasil GKG 13 persen lebih tinggi dibanding Aek Sibundong dengan penampilan tanaman lebih pendek. Galur ketan merah BP1002E-MR-2 mempunyai hasil 12 persen lebih tinggi dibanding varietas beras merah Aek Sibundong. Galur B11143D-MR-1-PN-3-MR-SI-2-3-PN-3 merupakan galur padi sawah berdaya hasil tinggi yang mempunyai hasil 12,6 persen lebih tinggi dibanding Ciherang. Galur B11953-MR-23-1-4, BP1002E-MR-2, dan B11844-MR-9-9-5 merupakan galur-galur yang mempunyai hasil stabil di tiga lokasi selama dua musim tanam.

Abstract

Grain yield improvement is the main objective in rice breeding programs. The objective of this study was to determine the phenotypic characters that have a direct or indirect effect on grain yield of double haploid lines. It expected can be used as selection criteria. The study was conducted on August 2009 at Cikeumeuh Bogor using randomized block design (RBD) with three replications. The materials used were 33 doubled haploid rice lines and three varieties/landraces rice. The results showed that number of productive tillers per hill, number of grains per panicle and 1,000 grain weight of rice can be used as selection criteria in improving grain yield. These three characters has a positive and very signifi cant correlation, positive and high direct effect on grain yield, and havea high heritability value.
