Characterization is the first stage in plant breeding that aims to reveal the morphological character and selection of the genotypes that adapt to low-altitude of area. To fulfill caisin consumption demands in Indonesia, extensification was needed from high altitude grounds which is the natural habitat of caisin to low-altitude. Randomize Complete Block Design (RCBD) is used and genotype as a single factor. 15 genotypes were used from collection of PKHT BRP 004, BRP 002, BRP 009, BRP 022, BRP 007, BRP 020, BRP 010, BRP 012, BRP 021, and those given the induction of mutations in BRP 004 R, BRP 002 R, BRP 009 R, BRP 003 R, and BRP 019 R. The data were analyzed by analysis of variance then Tukey test as the advanced test. BRP 010 genotype has the heaviest total harvest mass and harvest mass without the root, yet BRP 009 R genotype has the highest harvest index score which means it has the highest percentage of edible part. BRP 002 R, BRP 009 R, and BRP 019 R, are genotypes from the irradiation process that has color diversity. The result of analysis of variance showed that from 11 quantitative characters from 15 caisin genotypes, 3 characters was found not showing a true statistical difference, there are quantity of leaf, leaf width, and height ratio (NLP), and stalk width. BRP 022 Genotypes has the narrowest and the shortest leaf, the shortest leaf stalk, and the narrowest leaf diameter. BRP 002 has the highest plant height and Sri Tanjung genotype has the shortest plant height. BRP 010, BRP 004 R, BRP 002 R, BRP 019 R and BRP 009 R genotypes have potential to submitted for new varieties candidate that adaptive to low-altitude ground.

Penelitian ini bertujuan untuk mengevaluasi kemajuan seleksi dan segregan transgresif tanaman tomat generasi awal di bawah naungan. Penelitian ini terdiri atas 2 percobaan, dimana percobaan pertama dilaksanakan pada Juli – Oktober 2016 sedangkan percobaan kedua dilaksanakan pada Agustus – November 2017. Genotipe tomat SSH3 (suka naungan), 4979 (peka naungan) dan populasi F2 hasil persilangan SSH3 dan 4979 ditanam di Kebun Percobaan IPB, Pasir Kuda, Ciomas, Bogor pada percobaan pertama. Sebanyak 13 genotipe F3 (hasil seleksi populasi F2 pada percobaan 1), genotipe SSH3, genotipe 2979 dan populasi F2 hasil persilangan SSH3 x 4979 ditanam pada percobaan 2. Evaluasi kemajuan seleksi dan segregan hasil persilangan tomat suka naungan dan peka naungan, menunjukkan bahwa karakter jumlah buah dan bobot buah tomat menghasilkan nilai persentase kemajuan seleksi harapan yang tinggi namun menghasilkan persentase kemajuan seleksi yang lebih rendah. Karakter fruit set menghasilkan nilai persentase kemajuan seleksi harapan dan persentase kemajuan seleksi yang sama-sama tinggi. Sementara karakter vegetatif dan karakter buah tomat menghasilkan persentase kemajuan seleksi harapan dan kemajuan seleksi yang sama-sama rendah. Segregan transgresif banyak diperoleh berdasarkan karakter fruit set, lebih sedikit dihasilkan berdasarkan karakter jumlah dan bobot buah per tanaman, dan tidak dihasilkan berdasarkan karakter vegetatif dan karakter buah. Hal ini mengindikasikan bahwa karakter jumlah buah dan bobot buah per tanaman tomat lebih banyak dikendalikan oleh gen-gen non aditif, karakter fruit set lebih banyak dikendalikan gen-gen aditif pada kondisi di bawah naungan, dan tidak terdapat keragaman genetik pada karakter vegetatif dan karakter buah tanaman tomat pada populasi yang digunakan.

Molecular sex determination of five varieties of Indonesian papaya were investigated using RAPD (Random Amplified Polymorphism DNA) markers. Overall, 12 of 14 primers produced polymorphic bands on either several or all tested varieties. The OPC04 and RAPD2 markers could be used determined sex types on all varieties, whereas others primers are only on certain varieties. The Tangkai Ungu variety can be differentiate by markers: OPA11, OPA14, OPC14, RAPD2, RAPD3, and RAPD5; the Lokal Sumani can be determine using markers: OPA01, OPA11, OPA14, OPC01, OPC04, RAPD2, RAPD3, RAPD5, and RAPD6; the Merah Delima could be determined using OPC04, OPN09, RAPD2, and RAPD5; the Dampit could be determined using OPC01, OPC04, RAPD2, and RAPD6; whereas the Sicincing Panjang could be determined using OPA04, OPA11, OPA14, OPC04, RAPD2, and RAPD3.
