Abstract

A lot of plant materials are needed for successful back cross program of interspecific FI rice to their recurrent parents. Multiplication of the steril FI plants through tiller propagation is not adequate. The research aims to develop technique of vegetatif multiplication of interspesific hybrid rice utilizing nodal segments. In the vegetatif multiplication experiment, several factors were examined as treatments: nutrition culture (MS, Yoshida, and water), stum position (first, second and third) and growth media (vermiculite, husk charcoal, and sand). The plant materials are interspecific FI rice i.e. Ranah Sanra (genom AA) x O. officinalis 100870 (genom CC), Hawara Bunar (genom AA) x O. Punctata 9101411 (genom BB), Grogol (genom AA) x O. punctata 9101411 (genom BB), CT 6510-24-1-3 (genom AA) x O. malamphuzaensis 100957 (genom BBCC). Results of the study indicated that MS and Yoshida nutrition, stum without sheath, base of stum and sand media gave better growth more than other treatments.

Abstract

The objective of this study was to identify the stability of seven sweet corn genotypes as breeding result of Center for Crop Improvement Studies (PSPT), using Additive Main Effect Multiplicative Interaction (AMMI) method. The design was Randomized Complete Block Design (RCBD) with three replications as blocks. The genotypes used were; PSPT-C, PSPT-K, PSPT-T1, PSPST-T2, PSPT-MM, and two commercial varieties Bogor-Hi and SD-2. The genotypes were planted in four different locations which included experiment fields of IPB-Cikabayan Darmaga (250 m above sea level) and Pasir Sarongge Cipanas (1120-1200 m above sea level), Gunung Geulis Cisarua (550 m above sea level), and Cibedug Ciawi (600 m above sea level). Based on the postdictive success and predictive success methods, the model used (AMMI 2) was able to explain interaction-influenced variation as much as 85%. The genotypes found stable in four locations were PSPT-MM, PSPT-T1, Bogor-Hi and SD-2. PSPT-C was specific for Ciawi, PSPT-K and PSPT-T2 specific for Cisarua.   Key words: AMMI, sweet corn, multilocation trials.
