Abstract

The local Madura maize variety planted on drought stress area suffered retarded plant growth and reduced grain yield. Research was conducted to alleviate the stress on crop plants, to survive under drought condition. The aim of this study was to investigate the effects of MVA and ALA on the growth of Guluk-guluk local maize variety planted under difference drought stresess. The experiment was conducted using split-split plot design with three factors in six replications. The first factor was variation of MVA application, i.e., without inoculation (M0) and with inoculation of mycorrhiza (M1). The second factor was ALA treatment which consisted of 3 levels, namely 0% (P0), 0.05% (P1) and 0.1% (P2). Third factor was plant watering intensity, i.e., watered once every 2 days (K0), watered once every 4 days (K1) and watered once every 6 days (K2) reaching field capacity, respectively. Data were analyzed by two-way ANOVA and Duncan’s Multiple Range Test (DMRT). The results suggested that MVA and ALA treatments gave significant effects in increasing the percentage of mycorrhiza infection, total leaf P content, total chlorophyll content, plant height, fresh and dry weight of shoot and root and shoot/root ratio. It showed a significant effect in decreasing ABA content in maize plant subjected to drought stress. The ABA content was 1.7 ppm in plants watered once every 2 days, where control plant had ABA content of 5.8 ppm. The best treatment was found on plants treated with mycorrhiza inoculation and 0.05% ALA and watered once every 4 days.

Abstract

Blast is one of major disease on the upland rice in Indonesia. Upland rice lines derived from Kasalath and NILC443 crosses, containing Pup1 gen locus had been developed and evaluated for P fertilizer efficiency. Those lines would be evaluated for blast resistance, due to the fact that Pup1 locus contains genes involved in plant defend mechanism to disease, including blast disease. The BC2F5 plants derived from six crosses (DK, DN, SK, SN, BK, BN) were used in this research. Responses to blast disease in the green house were evaluated at ICABIOGRAD Bogor from March to April 2011, using combination of three blast races (race 173, 033, and 133). The response to blast disease in the field was evaluated at Taman Bogo Research Station, Lampung, and at farmer’s field in Cikeusal Village, Banten, from January to April 2011. Molecular analysis to trace Pup1 gene locus was conducted at the Molecular Biology Laboratory, using specific primer K20-2, from January to August 2013. Based on the molecular analysis all Pup1 lines showed homozygoes alleles, except the heterozygoes alleles on SK7, SK8, SK15, SK16, BN8 line, which were then not included in the next planting. The responses to blast at greenhouse among lines varied, but the Pup1 lines were mostly at level of moderate resistan (AT). Based on the result from the field experiment, most of Pup1 lines were resistance, however the susceptible check plant (Kencana Bali) did not show blast fungus infection. Differences of the result might be due to the blast testing at the green house which was more favorable for blast fungal growth. The effect of Pup1 gene locus showed clearly on resistance of plants obtained from Situ Bagendit cross, where Situ Bagendit was susceptible and does not contain the Pup1 locus. Additional of Pup1 locus in Situ Bagendit genome had increased the degree of resistant to blast.

Abstract

Breeding for high yielding rice varieties with VVEM (<90 days after sowing/ das) is considered important to increase cropping indexes in the fully irrigated farm lands. This research was aimed to evaluate the yield potential of 200 promising VVE and VE maturing rice lines. A total of 200 VVE and VE maturing rice lines and five check varieties (Ciherang, Dodokan, Inpari 1, Inpari 13, Silugonggo) were evaluated in Preliminary Yield Trial (PYT) at Sukamandi Experimental Farm using augmented design, during the dry season of 2012. The 17 lines selected from PYT along with three check varieties (Silugonggo, Inpari 13, Ciherang) were further evaluated in Advanced Yield Trial (AYT) using randomized complete block design at Sukamandi, Kuningan, Magelang and Klaten, during wet season of 2012. Of the 200 lines tested in PYT, three lines yielded significantly higher than the best check variety (Inpari 1) and 2 lines did equal to Inpari 1. A total of 155 lines were VVE (<90 das), and 45 lines were VE maturing (91-104 das). Based on yield per day, 17 lines were selected to be evaluated in AYT in WS 2012. Based on combined analyses from four locations of AYT, seven lines produced grain yield/ha and grain yield/day higher than did the best check Silugonggo (5.51 t/ha and 51.7 kg/day); there were14 lines did better than Ciherang (5.07 t/ha; 41.9 kg/day), and 13 lines yielded better than did Inpari 13 (5.27 t/ha; 46.7 kg/day). The best seven lines and lines with higher productivity per day than that of the best check, with an average yield of 5.62 t/ha up to 6.12 t/ha, with days to maturity from 87 up to 94 das, were ready to be evaluated in Multi Locational Yield Trial to meet the requirement for the release of new variety.
