Seleksi Induk Tanaman Bawang Merah

. Soedomo, R.P. 2006. The parent selection of shallots. Limiting genetic sources hindered breeding program of shallot. The breeding materials, must be selected and evaluated. The objective of this trial was to select and evaluate the phenotype and adaptability of shallot for breeding materials. This experiment was conducted at District of Tegal, Central Java (+ 5 m asl), from October to December 2005 (dry to rainy season), at alluvial soil. The experiment was set up in a randomized block design with 5 replications. The varieties of shallot used in this experiment were Ilokos, Bima Brebes, Bauji, Cokol Hijau, Singkil Gajah, Philipina, Timor, Bethok, Tiron, Kuning, Maja, Bangkok Warso, and Bombay. The results of this experiment showed that the potential cultivar for breeding materials were Tiron, Bethok and Bima Brebes cultivars, with survival rate i.e. 92.92; 91,2; and 81,54% respectively, moderate number of bulblet i.e. 9.90; 5.34 and 7.24 bulblet, respectively moderate number of leaf i.e. 35.50; 26.18; and 21.62 respectively, plant height (18.42; 27.20; and 23.62 cm), relatively big bulb size, with diameter 24.2/25.4; 23.6/27.6; and 22.4/26.6 mm respectively), relatively high production was rather yield i.e. dry bulb per plot 5,970.4; 5,107.0; and 4,915.20 g/6 m2 respectively; per hole 92.6; 76.6; and 76.7 g respectively, and per ha: 9.26; 8.51; and 8.18 t respectively. Weight losses was moderate i.e. 18.34; 19.03; and 21.73% respectively, and resistance of pest and diseases were moderate to good. Base on general phenotype appearance there were 6 to 10 groups considered as breeding materials
