Tanaman padi (Oryza sativa L.) merupakan komoditas tanaman pangan yang memiliki peran penting bagi kehidupan. Tanaman padi terus dikembangkan untuk memperoleh varietas unggul melalui program pemuliaan tanaman dengan persilangan. Penelitian ini bertujuan untuk mengetahui keragaman karakter agronomis, hubungan karakter agronomis dengan hasil tanaman, serta memperoleh genotipe populasi F2 hasil persilangan Pandanwangi x Inpari 32 yang berpotensi untuk dikembangkan pada generasi selanjutnya. Penelitian ini menggunakan rancangan acak kelompok augmented dengan faktor tunggal. Perlakuan terdiri dari genotipe F2 dan empat varietas pembanding. Data dianalisis menggunakan analisis ragam (ANOVA), uji lanjut Least Significant Increase (LSI), analisis korelasi Pearson, dan seleksi genotipe. Hasil penelitian menunjukkan bahwa tujuh karakter agronomis, yaitu tinggi tanaman, jumlah anakan total, jumlah anakan produktif, umur berbunga, jumlah gabah per malai, bobot gabah per rumpun, dan bobot 1000 biji, menunjukkan keragaman yang berbeda nyata antar genotipe. Jumlah anakan produktif, jumlah gabah per malai, persentase gabah isi, dan bobot 1.000 biji berkorelasi positif nyata terhadap bobot gabah per rumpun, sedangkan umur berbunga berkorelasi negatif nyata. Jumlah anakan produktif, jumlah gabah per malai, persentase gabah isi, dan bobot 1.000 biji berkorelasi positif nyata terhadap bobot gabah per rumpun, sedangkan umur berbunga berkorelasi negatif nyata. Berdasarkan hasil seleksi diperoleh enam genotipe terpilih, yaitu F60, F81, F2, F8, F38, dan F42 yang berpotensi dikembangkan pada generasi selanjutnya.

Rice (Oryza sativa L.) is a food crop that plays a vital role in human life. Rice is continuously being developed to produce high-yielding varieties through plant breeding programs involving crossbreeding. This study aimed to determine the diversity of agronomic traits, the relationship between agronomic traits and crop yield, and to identify F2 population genotypes resulting from the cross between Pandanwangi and Inpari 32 that have the potential for further development in subsequent generations. This study employed an augmented randomized block design with a single factor. Treatments consisted of F2 genotypes and four comparison varieties. Data were analyzed using analysis of variance (ANOVA), the Least Significant Increase (LSI) post-hoc test, Pearson’s correlation analysis, and genotype selection. The results showed that seven agronomic traits—plant height, total number of tillers, number of productive tillers, flowering time, number of grains per panicle, grain weight per plant, and 1,000-seed weight—exhibited significant differences among genotypes. The number of productive tillers, the number of grains per panicle, the percentage of filled grains, and the weight of 1,000 seeds were significantly positively correlated with grain weight per clump, whereas flowering time was significantly negatively correlated. The number of productive tillers, the number of grains per panicle, the percentage of filled grains, and the weight of 1,000 seeds were significantly positively correlated with grain weight per clump, whereas flowering time was significantly negatively correlated. Based on the selection results, six genotypes were selected—namely, F60, F81, F2, F8, F38, and F42—which have the potential to be developed in subsequent generations.
