Abstract

Penelitian bertujuan untuk mengevaluasi karakter-karakter penting pada nenas hibrida hasil persilanganantara Cayenne, Queen, A. bracteatus dan Merah. Penelitian dilakukan di Balai Penelitian Tanaman BuahTropika Solok mulai bulan Juni 2004 sampai Desember 2006. Materi genetik yang digunakan adalah nenashibrida hasil persilangan antara Cayenne x Queen (58 tanaman), Cayenne X A. bracteatus (24 tanaman) danCayenne x Merah (26 tanaman). Semua tanaman ditanam dalam polibag ukuran 40x50 cm. Pengamatandilakukan per individu tanaman terhadap karakter kualitatif dan kuantitatif. Hasil penelitian menunjukkan bahwadistribusi duri dan bentuk mata dipengaruhi oleh tetua betina. Persilangan Cayenne x Queen menghasilkanhibrida dengan persentase terbanyak pada ukuran mahkota kecil (≤ 100 g), dan rasa sangat manis (TSS > 20°brix ) berturut-turut 48.27% dan 8.62%. Persilangan Cayenne x A. bracteatus menghasilkan hibrida denganpersentase diameter hati kecil (≤ 1.5 cm) terbanyak, yaitu 50% . Persilangan Cayenne x Merah menghasilkanpersentase bobot buah > 1500 g terbanyak (23.07 %) dan persentase buah dengan tebal daging > 4 cmterbanyak (76.32%). Hibrida yang mempunyai karakter daun tidak berduri / duri hanya di ujung daun, rasasangat manis (TSS ≥ 20 °Brix ), dan bentuk mata lebar, adalah CQ-20, CB-1. Sedangkan hibrida dengan karaktertidak berduri / duri hanya di ujung daun, rasa sangat manis (TSS ≥ 20 °Brix ), dan bentuk mata menonjol adalahCQ-16, CQ-41. Informasi ini dapat digunakan sebagai pertimbangan untuk pemilihan tetua jantan dan betinadalam program perakitan varietas unggul nenas.Kata kunci: A. comosus, A. bracteatus, evaluasi, komponen hasil, mutu buah.ABSTRACT.The aim of the research was to evaluate the important characters of pineapple hybrids from crossingbetween Cayenne, Queen, A. bracteatus, and Merah parents. This research was conducted at the ResearchInstitute for Tropical Fruit in Solok, from June 2004 to December 2006 . Genetic materials used were 58 hybridplants from Cayenne x Queen crossing, 24 hybrid plants from Cayenne x A. bracteatus crossing, and 26 hybridplants from Cayenne x Merah crossing. All of the plants were planted on polybag with size 40x50 cm.Observation was done per plant on qualitative and quantitative characters. The results showed that thedistribution of spines on the leaves and the shape of eyes were affected by female parents. Cayenne x Queencrossing produced the most percentage of hybrids with small crown weight (≤ 100 g), and very sweet taste (TSS> 20° brix), i.e. 48.27% and 8.62% respectively. Cayenne x A. bracteatus crossing produced the mostpercentage of hybrids with small core diameter (≤ 1.5 cm) was 50% . Cayenne x Merah crossing produced themost percentage of hybrids with big fruit weight (> 1500 g) and flesh thickness > 4 cm. i.e. 23.07% and 76.32%respectively. The hybrid plants possessing the combined characters of spineless or spiny at the leaf tip, verysweet taste (TSS ≥ 20°Brix), and broad eyes were CQ-20 and CB-1. Meanwhile, hybrids with characters ofspineless or spiny at the leaf tip, very sweet taste (TSS ≥ 20°Brix), and projected eyes were CQ-16 and CQ-41.These results can potentially provide valuable information on the choice of female and male parents for theprograms of pineapple variety improvement.Key words: A.comosus, A. bracteatus, evaluation, yield component, fruit quality

Abstract

Tujuan penelitian adalah mendapatkan konsentrasi BAP yang tepat untuk memacu pertumbuhan stekbatang nenas. Penelitian telah dilakukan mulai bulan Maret 2010 sampai Agustus 2010 di Screen House BalaiPenelitian Tanaman Buah Tropika Solok. Perlakuan disusun dalam Rancangan Acak Kelompok (RAK) dengan 4perlakuan dan 5 ulangan. Perlakuan adalah dosis BAP (0, 200, 400, dan 600 ppm). Setiap unit perlakuan terdiriatas 8 stek. Hasil penelitiaan menunjukkan bahwa perendaman BAP berpengaruh nyata terhadap saat muncultunas, tinggi tanaman, jumlah daun, jumlah tunas, tetapi tidak berpengaruh nyata terhadap jumlah akar utamapada umur 17 minggu setelah tanam. Perendaman stek batang dalam 600 ppm BAP memberikan pengaruh yangterbaik, yaitu saat muncul tunas (36,60 hst), tinggi tanaman (17.55 cm), jumlah daun (28.76 helai), dan jumlahtunas (1.87 tunas) dibandingkan perlakuan lainnya.Kata kunci : Ananas comosus, Benzyl Amino Purine (BAP), stek batang ABSTRACTThe aim of this research was to obtain the proper concentration of BAP to accelerate the growth ofpineapple stem cuttings. The research was conducted from March 2010 until August 2010 at Screen House ofthe Indonsian Tropical Fruits Research Institute, Solok, West Sumatera. The treatments arranged in arandomized block design with 4 treatments and 5 replications. The treatment is a dose of BAP (0, 200, 400, and600 ppm). Each experimental unit consists of 8 cuttings. The results showed that BAP significantly affect thetime emerge shoots, plant height, leaf number, number of shoots, but did not significantly affect the number ofprimary roots at the age of 17 weeks after planting. Dipping stem cuttings in 600 ppm BAP gave the best effect,i.e. the shoots emerge (36.60 days after planting), plant height (17.55 cm), number of leaves (28.76 leaves), andnumber of shoots (1.87 shoots) than other treatments.Keywords : Ananas comosus, Benzyl Amino Purine (BAP), stem cutting

Abstract

Guava has several different accessions. Guava diversity needs to be studied and evaluated in order to determine the next steps in the guava breeding. The objective of this research was to characterize and cluster of some guava germplasm collections. The study was conducted at Aripan and Subang experimental farm, Indonesian Tropical Fruit Research Institute from January 2012 to December 2012. Five fruits of each accession were randomly selected sampled and then characterized using UPOV guidelines. Obtained data were analyzed by NTSYS ver.2.1. The Similarity level of 19 accessions ranged from 70 – 90% or the genetic distance was between 0-20%. Dendogram obtained could be clustered into two different groups, namely group I (ARP9406, ARP9407, ARP8653, ARP8742, ARP10.2, JBT001, JBT002, ARP8740, JBT003 and JBT004), group II (ARP10.7, ARP10.6, ARP10.1, ARP10.12, ARP10.9, ARP10.11, ARP8744, ARP8741 and ARP8743). The result of this research can be used for guava breeding. Species diversity and genetic resources are very important to get new varieties. This study would be highly valuable in the future. Keywords :  Guava  Germplasm, Characterization, Clustering
