Abstract

ABSTRACTThe quality and quantity of feed silkworm affect the yield and quality of cocoon. Crossing among mulberry species was conducted in order to obtain new hybrids with higher productivity. This study aimed to select mulberry hybrid for highland cultivation purpose. Survival rate, length of branches, number of branches, and weight of wet leaves were measured to determine the productivity of five mulberry hybrids. Mulberry hybrids Morus cathayana x M. amakusaguwa IV.10 and M. cathayana x M. amakusaguwa IV.12 are selected hybrids for highland cultivation.Both hybrids produced leaves production increment by 158% and 145% compared to M. cathayana as control.Keywords: Highland, hybrid, mulberry and productivity.,ABSTRAKKualitas dan kuantitas pakan ulat sutera mempengaruhi produksi dan kualitas kokon. Persilangan antar spesies murbei telah menghasilkan hibrid baru dengan harapan mempunyai produktivitas yang lebih tinggi. Penelitian ini bertujuan untuk mendapatkan hibrid murbei yang optimal untuk dikembangkan di dataran tinggi. Lima hibrid baru diuji produktivitasnya berdasarkan nilai persentase tumbuh, panjang cabang, jumlah cabang serta bobot daun basah per tanaman. Hasil penelitian menunjukkan murbei hibrid Morus cathayana x M. amakusaguwa IV.10 dan M. cathayana x M. amakusaguwa IV.12 paling optimal untuk dikembangkan di daerah tinggi. Kedua hibrid tersebut menghasilkan peningkatan produksi daun sebesar 158% dan 145% dibandingkan M. cathayana sebagai kontrol.Kata kunci: Dataran tinggi, hybrid, murbei dan produtivitas

Abstract

This study was conducted to evaluate plant growth of Intsia bijuga at 5 years old in Sobang, Banten for supplying good genetic material in the future. Establishment of the trial was conducted in 2007 using Randomized Complete Block Design (RCBD) that consisted of 6 blocks, 100 families nested in 10 provenances, 4 treeplot for each family with a spacing of 4 x4 m. Measurements were taken periodically every year on the survival percentage, total height and stem diameter at the breast height or dbh. At the age of 5 years showed that the significant differences among provenance in survival percentage that ranged from 41.61 to 65.11 %,  average of plant height were 1.04 to 2.82 m and dbh 1.24 to 1.59 cm. The growth variation families also showed significant differences in height and diameter. The survival rate ranged from 12.5-91.67 %, average plant height were 0.52-2.55 m and dbh 0.90-2.44 cm. Individual tree heritability estimate for height was height (0.344) while that of diameter was moderate (0.259). Family heritabilities for height and diameter was considered moderate, namely 0.573 and 0.491 respectively. Genetic correlation between height and diameter growth was positive and high (0.834).
