ANALISIS KARAKTERISTIK FISIKOKIMIA BERAS PUTIH, BERAS MERAH, DAN BERAS HITAM (Oryza sativa L., Oryza nivara dan Oryza sativa L. indica)

This study aims to determine the effect of giving brown rice (Oryza nivara) and black rice (Oryza Sativa L. Indica) to changes in blood glucose levels in people with diabetes mellitus in Kendari City. This research method was carried out with a quasi-experimental design with a pre-post test design test. The results of the study on checking blood glucose levels before and after giving brown rice (Oryza nivara) and black rice (Oryza sativa L. indica) within one week obtained P-Value = 0.000 from P-Value <0.05, while in comparison between brown rice (Oryza nivara) and black rice (Oryza sativa L. indica) on changes in blood glucose in people with diabetes mellitus in Kendari City obtained P-Value = 0.19 from P-Value < 0.05. In conclusion, there is an effect of giving red rice (Oryza nivara) and black rice (Oryza sativa L. indica) on changes in blood glucose in people with diabetes mellitus in Kendari City.

Two Factors

The objectives of this research is the effect of straw and range on the yield of rice (Oryza sativa L). The method of the research use factorial design based on the Randomized Block Design with two factors of treatment. The first factor was straw (without straw (P0), fermented straw (P1) dan straw burned (P2)) and second factor was range (spacing of 25 x 20 cm (J1), spacing of 25 x 25 cm (J2) and spacing of 25 x 30 cm (J3)) and each kombination of treatment three times replicated so that it is obtained 9 trial combinations and 27 trial plots. The result of the research : (1) There was not interaction between straw and range on the yield of rice (Oryza nivara). (2) The highest yield was treatment P1(fermented straw) for all parameters except plant height in 14 hst, penicle length per clump and weight of 1000 grains of dry grains milled. (3) The highest yield was treatment J3 (spacing of 25 x 30 cm) for all parameters except weight of grain per plot dan weight of 1000 grains of dry grains milled. Key word : straw, range and interaction.

Oryza Nivara

SummaryBacterial blight (BB) of rice caused by Xanthomonas oryzae pv oryzae (Xoo) is one of the major constraints to productivity in South-East Asia. The strategy of using major genes, singly or in combination, continues to be the most effective approach for BB management. Currently, more than two dozen genes have been designated but not all the known genes are effective against all the prevalent pathotypes. The challenge, therefore, is to continue to expand the gene pool of effective and potentially durable resistance genes. Wild species constitute an important reservoir of the resistance genes including BB. An accession of Oryza nivara (IRGC 81825) was found to be resistant to all the seven Xoo pathotypes prevalent in northern states of India. Inheritance and mapping of resistance in O. nivara was studied by using F2, BC2F2, BC3F1 and BC3F2 progenies of the cross involving Oryza sativa cv PR114 and the O. nivara acc. 81825 using the most virulent Xoo pathotype. Genetic analysis of the segregating progenies revealed that the BB resistance in O. nivara was conditioned by a single dominant gene. Bulked segregant analysis (BSA) of F2 population using 191 polymorphic SSR markers identified a ∼35 centiMorgans (cM) chromosomal region on 4L, bracketed by RM317 and RM562, to be associated with BB resistance. Screening of BC3F1 and BC2F2 progenies and their genotyping with more than 30 polymorphic SSR markers in the region, covering Bacterial artificial chromosome (BAC) clone OSJNBb0085C12, led to mapping of the resistance gene between the STS markers based on annotated genes LOC_Os04g53060 and LOC_Os04g53120, which is ∼38·4 kb. Since none of the known Xa genes, which are mapped on chromosome 4L, are effective against the Xoo pathotypes tested, the BB resistance gene identified and transferred from O. nivara is novel and is tentatively designated as Xa30(t). Homozygous resistant BC3F3 progenies with smallest introgression region have been identified.

Treated Plot

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.
