Abstract

The growth of Pak Choy (Brassica rapa var. chinensis) using nutrients from catfish “Sangkuriang” (Clarias gariepinus) wastes was investigated in the household scale aquaponics systems by comparing the growth parameters value among the grow beds. The growth parameter of Pak Choy was fresh weight, leaf number, and leaf area. Meanwhile, catfish growth parameters were body weight and length, and feed conversion ratio (FCR). The experiments were arranged in a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The data were analyzed using Analysis of Variance (Anova) followed by Duncan Multiple Range Test (DMRT) at 95% level of significant The result of the study showed that there were not significantly different in the growth parameter of Pak Choy among the grow beds in the vertical system. However, those in grow beds “Ä” were significantly higher than the rest of the grow beds in the horizontal aquaponics system. In general, all the growth parameter of Pak Choy in the vertical system was higher than in the horizontal one, although, it was not statistically significantly different. Nevertheless, the horizontal aquaponics system gave better results in the body weight and FCR of catfish.

Abstract

SSR marker is one of the genetic markers widely applied in plant breeding programs. The application of molecular markers in plant breeding is meant to accelerate the selection of cross-progeny. The research aimed to identify the SSR primers polymorphism between the parent and control that linked to Al tolerance and verify the cross-progeny of five crosses. The result gained from 37 SSR primers used in this study showed that only nine primers are polymorphic. These nine polymorphic primers are RM257, RM214, RM247, RM205, RM490, RM262, RM569, RM271, and RM19. The application of polymorphic markers on five cross-progeny which have shown the same band pattern as the parents and tolerant control on the use of 9 SSR primers recorded as follows: RM257 2 lines, RM214 5 lines, RM247 5 lines, RM205 lines, RM490 13 lines, RM262 5 lines, RM569 7 lines, RM271 4 lines, and RM19 6 lines. The selected SSR primers linked to Al tolerance in this research can be used as a reference for molecular breeding strategies to develop new Al tolerance rice varieties in dryland conditions.
