Abstract

One of the important issues on rice breeding is to develop new rice lines suitable for nitrogen efficiency in the suboptimum environment. The study aimed to evaluate the tolerance and yield components of rice breeding lines selected under low and high nitrogen conditions. The F6 generation from two cross-combinations of Gampai/IR77674 and Progol/Asahan, were evaluated in the dry season of 2014 under N suboptimum and N optimum conditions. A total of 172 lines plus six check varieties derived from the low and high N environment selection were evaluated under low N rate (34.5 kg N ha-1) and high N rate (138 kg N ha-1), arranged in an augmented design. Six check varieties were relocated three times in each block. Plot size was 5.5 m2 and plant spacing 20 cm x 20 cm. Data were collected for grain yield and major yield components. Results showed that the different status of nitrogen fertilizer affected the number of productive fillers, number of filled grains, 100-grain weight, and grain yield. Different cross combinations exhibited different results in the progeny performance. Ten lines have a higher yield also tolerant to low N condition, i.e. B14250F-6-9, B14250F-1-4, B14250F-9-9, B14250F-6-4, B14250F-5-2, B14262F-15-6, B14250F-2-6, B14262F-12-4, B14250F-5-1, and B14250F-11-4. Thus, to obtain the N tolerant lines, selection at a low N environment was more effective compared with the optimum selection environment.

Abstract

Anther culture provides the quick route in obtaining pure lines in a single generation from either green haploid plant that may be artificially or spontaneously doubled. Indica rice known as recalcitrant genotype because of its difficulty in regenerating sufficient number of green plantlets among the regenerated plants through anther culture. Whilst, research on studying anther culture ability has to be done to assure the success of rice breeding through anther culture. The objective of this research was to determine regeneration ability of five accessions of indica rice tolerance to aluminum through application of putrescine in anther culture. Completely randomized design with 15 replications was used in this research. Treatments consisted of five accessions of aluminum tolerance indica rice, ie. CT6510-24-1-3, Grogol, Hawara Bunar, Krowal, and Sigundil. Callus induction medium based on N6 medium + 10-3 M putrescine, while regeneration medium based on MS + 10-3 M putrescine. The results indicated that culture ability is controlled by the genotype. From this research, Grogol, Krowal and Sigundil were selected as accessions having good rice anther culture ability, and therefore can be used as parents for developing new rice varieties tolerance to aluminum through anther culture.

Abstract

Improvement of rice for durable resistance rice blast is difficult due to the complexity of the inheritance of resistance. As study was conducted to analyze blast resistance in rice using two different approaches, i.e., blast QTL mapping and comparison of resistance spectrum and genetic control. The blast QTL mapping was done using an interspesific population originated from backcrossing between a wild rice, Oryza rufipogon, and a cultivated rice, IR64. Comparison of resistance spectrum and genetic control was based on phenotypic reactions. Results of the experiment showed that based on the blast QTL mapping, genes Pirf2-1(t) and Pir2-3(t) were mapped on chromosome 2. Gene Pirf2-1(t) was isolated from chromosome 2 of O. rufipogon and coding for resistance to P. grisea race 001, while gene Pir2-3(t), which was isolated from rice cultivar IR64, was coding for resistance to P. grisea race 173. Based on the resistance spectrum, O. rufipogon has a non-race specific resistance. Gene Pirf2-1(t) on O. rufipogon contributed a dominant mode of resistance to blast which was affected by a duplicate epistasis. The other gene, Pir2-3(t) contributed an additive mode of resistance which was affected by a complementary epistasis.

Abstract

An experiment was conducted at the Molecular Biology and Genetic Engineering Laboratory of BB-Biogen, Bogor with an objective to obtain transgenic soybean plants containing the proteinase inhibitor II (pinII) gene. The experiment consisted of three steps, i.e., optimalization of the soybean transformation technique using the gus gene; transformation of soybean using the pinII gene, and molecular analysis of the transformed soybean plants. Two type of explants (young embryo and cotyledon) were bombarded with pRQ6 plasmid containing the gus gene with the following treatment: Helium gas pressure (1100 psi and 1300 psi), shoot distance (5 and 7 cm), and number of bombardment (1x and 2x). The result of gus assay indicated that the best bombardment was done on young cotyledon explants with 1100 psi Helium pressure, shoot distance 5 cm, and 1x bombardment. Transformation of the soybean explant using the pinII gene (inside the pTWa plasmid) was conducted using the best bombardment treatment from the first activity. Two plants from c.v. Wilis (WP1, WP2) and three plants from c.v. Tidar (TP1, TP2, TP3) were recovered from regeneration and selection of the transformed explants. Molecular analysis of the regenerated plants using the PCR technique showed that only WP2 contained the pinII gene. This plant was fertile and will be used for further evaluation.

Abstract

Tolerance of Transgenic Tobacco Expressing P5CS Gene Against Drought Stress. Drought is majorosmotic stress that dramatically limit plant growth and productivity. Proline accumulation has been correlatedwith tolerance to drought stress in plants. Therefore, overproduction of proline in plants may lead to increasedtolerance against these abiotic stresses. The objectives of this experiment were to determine the effects of droughtstress at the period of 15 – 90 days after planting (DAP) on growth of T1 plants derived from transgenic GStobacco, to evaluate their tolerance against drought stress, and to determine their leaf proline content. One groupof the tobacco plants were grown in plastic pots and subjected to stress condition during the period of 15 – 90DAP. The other group was grown optimally in plastic pot up to harvest period. All tobacco plants were harvestedat 91 DAP. Leaf proline content was determined at 63 DAP (after six periods of stress). The results indicatedreduced plant height, shoot diameter, leaf number, leaf dry weight and leaf area of all tobacco plants. Stresssensitivity index calculated using leaf dry weight character grouped T1 plants derived from P5CS transgenicGS tobacco into tolerance, medium tolerance and sensitive against drought stress while that of non-transgenicGS tobacco were only medium tolerance and sensitive against drought stress. Higher leaf proline content underdrought stress was observed in all T1 plants derived from P5CS transgenic tobacco than that of non-transgenicGS tobacco. These data demonstrated that proline accumulation as an osmoprotectant and that over-expressionP5CS gene results in the increased tolerance to osmotic stress in T1 plants derived from P5CS transgenic tobacco.Key words: Proline biosynthesis, proline accumulation, sensitivity index, biomass yield Stres kekeringan merupakan masalah utama stres osmotik yang dapat menjadi faktor pembataspertumbuhan dan produktivitas tanaman. Akumulasi prolina berkorelasi dengan tingkat toleransi tanamanterhadap stres kekeringan. Oleh karena itu over-produksi prolina diduga dapat meningkatkan toleransi tanamanterhadap stres kekeringan. Tujuan penelitian ini adalah (1) untuk mengevaluasi pengaruh stres kekeringanmelalui pengurangan air terhadap pertumbuhan dan hasil tanaman TI zuriat dari tembakau GS transgenik P5CSgenerasi TO, (2) menganalisis akumulasi prolina daun tanaman TI zurlat dari tembakau GS transgenik P5CSgenerasi TO kondisi stres dan non-stres, serta (3) menganalisis hubungan antara akumulasi prolina daun padakondisi stres kekeringan dengan pertumbuhan dan hasil tanaman. Percobaan dua faktor (tembakau transgenikstres kekeringan) disusun dengan rancangan acak kelompok. Sebagian tanaman yang diuji disiram setiap hari hingga mencapai kondisi kapasitas lapang dari awal tanam sampai dengan 90 HST dan digunakan sebagaiperlakuan non-stres. Sedangkan kelompok tanaman yang lain dipelihara dalam kondisi kapasitas lapanghingga 14 HST dan diberi perlakuan stres kekeringan dari umur 15 HST hingga panen (90 HST). Kandunganprolina diukur pada umur 63 HST (setelah 6x periode stres). Hasil penelitian menunjukkan semua tanamantembakau yang diuji mempunyai tinggi tanaman, diameter batang, jumlah, berat kering dan luas daun yanglebih rendah akibat perlakuan stres kekeringan yang diberikan dibandingkan dengan kondisi non-stres.Berdasarkan hasil perhitungan indeks sensitivitas terhadap stres kekeringan menggunakan peubah bobotdaun kering per tanaman maka tanaman TI zurlat dari tembakau GS transgenik P5CS generasi TO yang diujibersegregasi untuk kategori toleran, medium toleran dan peka, sedangkan tembakau GS non-transgenikdikategorikan sebagai medium toleran dan peka terhadap stres kekeringan. Tanaman TI zurlat dari tembakau GStransgenik P5CS generasi TO menunjukkan kandungan prolina yang lebih tinggi dalam kondisi stres kekeringandibandingkan dengan tembakau GS non-transgenik. Peningkatan akumulasi prolina yang cukup tinggi akibatover-ekspresi dari gen P5CS diduga berkorelasi dengan peningkatan toleransi tanaman terhadap stres kekeringan.Kata kunci : Biosintesis prolina, akumulasi prolina, indeks sensitivitas terhadap stres, produksi biomasa

Abstract

Perakitan varietas unggul yang memiliki sifat ketahanan terhadap pathogen blas (Pyricularia grisea) merupakan salah satu program utama dalam pemuliaan padi. Untuk mendukung program tersebut diperlukan gene pool yang luas terutama untuk trait kuantitatif. Salah satu strategi yang dapat ditempuh adalah dengan mengidentifikasi lokus kuantitatif (QTL) yang terdapat pada spesies liar dan mentransfernya ke dalam kultivar padi. Spesies padi liar Oryza rufipogon diidentifikasi mempunyai lokus ketahanan kuantitatif (QRL) terhadap patogen blas. Pemanfaatan marka molekuler dalam pemuliaan tanaman salah satunya adalah untuk mempercepat seleksi (MAS) kembalinya genom tetua pemulih dalam persilangan silang balik. Dalam rangka menseleksi progeni persilangan O. rufipogon dengan IR64 menggunakan marka molekuler, dalam penelitian ini dilakukan seleksi introgresi genotip tahan yang hanya sedikit membawa fragmen dari tanaman padi liar. Tujuan dari penelitian ini adalah menseleksi genotip tahan blas dan menganalisis introgresi dan keterpautannya dengan tentative QTL tahan blas. Hasil analisis menunjukkan terdapat 20 genotip tahan dengan tingkat introgresi yang bervariasi dari 9%–40% dari total kromosom yang terpetakan. Analisis keterpautan menunjukkan bahwa genotip nomor 118 mempunyai QTL tahan blas pada kromosom 2, genotip nomor 337 mempunyai QTL tahan blas pada kromosom 12 dan genotip nomor 343 mempunyai QTL tahan blas pada kromosom nomor 9. Nomor-nomor genotip yang telah terseleksi tingkat ketahanan dan introgresinya dapat mempercepat kembalinya genome tetua pemulih, sebagai bahan untuk pembentukan populasi lebih lanjut.

Abstract

Model genetik ketahanan terhadap penyakit bulai pada jagung yang disebabkan oleh Peronosclerospora maydis telah diestimasi pada progeni yang berasal dari persilangan antara galur resisten Mr10 dan Nei9008, serta galur rentan CML161. Tujuh generasi dari tiap-tiap persilangan (tetua P1 dan P2, F1, F2, F3, BC1P1, dan BC1P2) telah ditanam di Kebun Percobaan Cikeumeuh-Bogor. Percobaan ditata mengikuti rancangan petak terbagi dengan dua ulangan. Materi genetik dievaluasi ketahanannya terhadap penyakit bulai dengan menggunakan teknik tanaman baris penyebar. Uji skala gabungan digunakan untuk menentukan model genetik yang sesuai. Uji-t pada level 5% dan 1% mengindikasikan bahwa komponen genetik aditif [d], dominan [h] dan interaksi aditif × aditif [i] berperan penting untuk karakter ketahanan terhadap penyakit bulai pada jagung. Nilai komponen genetik aditif dan dominan yang bertanda sama dengan interaksinya pada pasangan persilangan Mr10 × CML161 menunjukkan adanya interaksi gen yang bersifat komplementer epistasis, sedangkan pada pasangan persilangan Nei9008 × CML161, komponen genetik aditif dan dominan berlawanan tanda dengan interaksinya menunjukkan adanya interaksi gen yang bersifat duplikat epistasis. Nilai heritabilitas dalam arti luas tergolong tinggi, sedangkan heritabilitas dalam arti sempit tergolong sedang.
