چکیده
Golden rice merupakan padi yang di dalam endosperma bijinya memiliki kandungan β-karoten atau provitamin A. Beberapa upaya telah dilakukan untuk meningkatkan ketahanannya terhadap penyakit blas dan hawar daun bakteri (HDB). Hasil pemuliaan mendapatkan turunan ke 8 (F8) bersifat stabil. Penelitian ini bertujuan mengkarakterisasi agromorfologi genotipe galur introduksi F8 PAC Nagdong/IR36/IR64. Laboratorium Agroteknologi, Fakultas Pertanian, Universitas Jember. Benih digunakan yaitu tiga intorduksi Nagdong/IR36/IR64 dengan kode 302/IR-2-2(6)/1, 302/IR-2-2(7)/2, 302/IR-2-2(8)/1 serta varietas IR36 IR64 sebagai tanaman kontrol. Analisis meliputi gen Pik-s, Pi54, Pi-ta, Xa4 Xa7. penelitian menunjukkan bahwa karakter pada seluruh tinggi tanaman, jumlah anakan produktif tidak berbeda nyata. Tinggi termasuk kategori semidwarf, >24.6 mencapai lebih dari 85%, panjang malai antara 20.09-20.85 cm, bobot per rumpun 42.94 g pengkode sifat tahan HDB.

Proof. There are three cases: (1) A and B are in the same column. Then, since in each column we picked the shortest student, A is shorter than B. (2) A and B are in the same row. Then, since in each row we picked the tallest student, B is taller than A. (3) A and B are neither in the same row, nor in the same column. Let C be a student who is in the same row as A and in the same column as B. Th...

An objection to the memetic approach to culture Memetics is one possible evolutionary approach to the study of culture. Boyd and Richerson's models (1985, Boyd this volume), or my epidemiology of representations (1985, 1996), are among other possible evolutionary approaches inspired in various ways by Darwin. The memetic approach is based on the claim that culture is made of memes. If one takes...

Many scientists have until recently considered consciousness to be unsuitable for scientific research. As Damasio remarks, ‘studying consciousness was simply not the thing to do before you made tenure, and even after you did it was looked upon with suspicion’ (Damasio, 1999, p. 7). Prompted by technological developments as well as conceptual changes, this attitude has changed within the last de...

To present the application of the XOR Theorem to learning theory we rst give the following two de nitions. Let F be a class of boolean functions and let > 0. A strong learning algorithm for F over the uniform distribution queries the function f : f0; 1gn ! f0; 1g and outputs, with probability at least 1 , a circuit C such that Pr[f(x) 6= C(x)] < 1 nO(1) where Pr is the uniform distribution. The...
