Early-maturing and high-yielding rice variety is very useful for increasing rice production in Indonesia. The aim of this research was to develop new lines of Indonesian rice containing Hd2 gene using Code variety as a recipient parent and Nipponbare variety as a donor parent through targetted MAB approach using RM1362 and RM7601 in chromosom 7 for foreground selection. After two generations of backcrossing, the positive alleles of Hd2 gene from Nipponbare had successfully trans-ferred into Code. The plant number CdNp_29 in BC2F2 popula-tion had the highest genome recovery of 82.7%. The twelve BC2F3 plants were selected for self-pollination to generate BC2F4. These selected lines that carried the Hd2 gene were screened in the greenhouse for the evaluation of heading date and agronomic traits. All improved lines had Hd2 gene similar to the donor parent Nipponbare. The heading date of the breeding lines ranged from 73 to 89 days (Code 85 days) or fill the third criterion of rice maturity that is 103-104 days compared to Code of 116-119 days, whereas their agronomic performances were similar with that of Code. Application of MABc for im-proving rice early maturity has accelerated the development and selection in early generation of superior lines having genetic background of Code. It is expected that the newly developed lines of Code will be utilized to increase rice production in Indonesia.

Heading date is one of key traits in rice adaptation to different environments. Rice with early maturity is very useful for increasing rice production extensively especially in Indonesia. The improvement of rice variety Conde for heading date and resistance to bacterial leaf blight (BLB) was developed through Marker Assisted Backcrossing approach (MAB). Xa7 derived from Conde as recipient parents for resistance to BLB and Hd2 gene derived from Nipponbare as a donor parent for heading date. The aim of this research was to evaluate the performance of heading date and agronomic traits of 85 BC2F4 lines in two field stations, Sukamandi (West Java) and Maros (South Sulawesi). Molecular analysis of Xa7 on chromosome 6 and Hd2 gene on chromosome 7 and agronomic performance was evaluated. Foreground analysis resulted 41% for Xa7 and 66.7% for Hd2 gene in homozygous condition. The majority of lines have similar heading date and yield with Conde and more resistance to bacterial leaf blight (BLB) than Conde. Six lines flowered earlier 5 days than Conde in Sukamandi and three lines flowered earlier 3 days in Maros. Twelve lines with flowered earlier than Conde, resistance to BLB and similar yield with Conde were selected for background analysis resulted 93% genome recovery. These lines would be further evaluated in preliminary yield trail for their stability.

The sustainability and increasing the national rice production require the readiness of food and agriculture sector cope with the impacts of climate change, land degradation, drought area, sloping production and the raising of population growth. Adaptation plays an important role in ensuring the sustainability of food security. This research aimed to develop drought-tolerant variety of Inpari 30 (submergence tolerance variety) and Situ Bagendit through marker-assisted backcrossing-through pyramiding gene of identified QTLs for foreground selection and to explore SSRs and 6K SNPs for background selection distributed in 12 rice chromosome of drought tolerant donor (Cabacu) and recipient rice (Inpari 30 and Situ Bagendit). The foreground selection revealed that flanking SSRs of each QTLs (qRPF2.1, qGPP2.1, qSPP4.1 and Sub1) was less than 2 cM. The background selection through polymorphic survey of Rice 6K SNP primers revealed 2457 (53,3%) polymorphic SNPs on Inpari 30 vs Cabacu and 2563 (55,6%) polymorphic SNPs on Situ Bagendit vs Cabacu with the average distance about 0.74 cM/chromosome. The genotypic selection of F1 Inpari 30/Cabacu and F1 Situ Bagendit/Cabacu have already in heterozygote condition for these 4 QTLs target. These lines was continued for backcross breeding to develop BC1F1 Inpari 30/Cabacu and BC1F1 Situ Bagendit/Cabacu generation.

Sumbawa horse milk is one of the local products in Sumbawa (West Nusa Tenggara). There is no research so far which discusses the potencies of LAB metabolite compounds as antimicrobials and probiotics for treating Diabetes Mellitus type 2. This study aims to obtain the antimicrobial and inhibitory activity of the LAB-extracted metabolite compounds from Sumbawa horse milk collected from Penyaring village and Lennanguar village, Sumbawa, West Nusa Tenggara, Indonesia. LAB metabolites are extracted by using 96% ethanol. It has been found that metabolites extracted from media culture of LAB SKP K.9 (E. thailandicus) have the highest antimicrobial activity against S. aureus (ATCC 6538) (2.5 cm), S. typhimurium (2.5 cm), L. monocytogenes (BTCC B693) (2.53 cm) and EPEC K.1.1 (2.7 cm) when compared with other LAB isolates. Moreover, the inhibition of α-glucosidase enzyme obtained from LAB SKP K.5 isolate (L. garvieae) is 6.25%, 39.28% from LAB SKP K.9 (E. thailandicus), 53.57% from LAB SKP K.3 (W. confusa), 67.85% from LAB SKL K.4 (L. fermentum), and 78.57% from LAB SK 1.5 (E. faecium). The extract of LAB SK 1.5 metabolite compound (E. faecium) has the highest inhibitory activity against the α-glucosidase enzyme (78.57%) compared to other LAB isolates.
