Abstract


Penelitian dilakukan di desa Banjarsari (±5 m dpl), Probolinggo, Jawa Timur, mulai bulan Nopember 2000 sampai September 2001 menggunakan rancangan acak kelompok lengkap. Perlakuan terdiri dari 10 hasil persilangan dan 3 ulangan. Peubah yang diamati adalah saat muncul bunga pertama, letak bunga pertama, letak buah jadi yang pertama, umur panen buah pertama, panjang tangkai buah, panjang buah, diameter buah, tebal buah, jumlah biji, berat buah, jumlah buah, hasil, padatan terlarut total, kadar air, dan kadar vitamin A. Hasil penelitian menunjukkan bahwa hampir semua karakter berbeda nyata di antara hibrida F1 kecuali saat muncul bunga pertama, letak bunga pertama, kadar air buah, dan vitamin A. Hibrida F1 dari persilangan 99-015 x 99-020, 99-015 x 99-017, dan 99-020 x 99-017 mempunyai karakter unggul yang paling banyak (7 karakter). Hibrida F1 yang mempunyai letak buah jadi yang pertama yang rendah ditampilkan oleh persilangan 99-015 x 99-020, 99-015 x 99-017, dan 99-020 x 99-017. Hibrida F1 yang mempunyai umur panen buah pertama yang paling cepat ditampilkan oleh persilangan 99-015 x 99-017. Hampir semua hibrida F1 mempunyai hasil yang tinggi kecuali dari persilangan 99-015 x 99-010, 99-014 x 99-010, dan 99-010 x 99-017. Hibrida F1 dari persilangan 99-015 x 99-017 mempunyai keunggulan letak buah jadi yang rendah, umur panen buah pertama yang cepat, hasil tinggi, dan padatan terlarut total yang tinggi. Hasil ini dapat digunakan untuk memilih hibrida F1 dalam rangka peningkatan produktivitas dan kualitas pepaya.

ABSTRACT. Indriyani, N.L.P. 2007. Phenotypic Performance of some F1 Hybrids of Papaya. The aim of the research was to obtain the best phenotypic performance of papaya hybrids. The experiment was conducted at Banjarsari (± 5 m asl), Probolinggo, East Java, from November 2000 to September 2001, using a randomized complete block design. The treatment consisted of 10 populations of artificial cross pollination and 3 replications. Parameters observed were time of first flower emergence, first flower position, first fruit position, harvest time of first fruit, length of fruit stalk, fruit length, fruit diameter, flesh thickness, seed number, fruit weight, fruit number, yield, total soluble solid, moisture, and vitamin A. The results showed that almost all of characters observed among the hybrids were significantly different with exception for emergence of first flower, position of first fruit, moisture, and the vitamin A. Among 10 hybrids, 3 F1 hybrids were found to have highest superior character (7 characters). The lowest of first fruit position was presented by F1 hybrid from crossing of 99-015 x 99-020, 99-015 x 99-017, and 99-020 x 99-017. The earliest of harvest time of first fruit was presented by F1 from 99-015 x 99-017. Almost all of F1 hybrids were found to have high yield except for F1 hybrid of 99-015 x 99-010, 99-014 x 99-010, and 99-010 x 99-017. The lowest of first fruit position, the earliest of harvest time of first fruit, high yield, and high total soluble solid was presented by F1 hybrid of 99-015 x 99-017. This results can be used to select F1 hybrid in supporting the productivity and quality of papaya.
