Abstract

Resistance evaluation of modern rice varieties to brown planthopper Nilaparvata lugens STÃ…L. The research was performedto understand the resistance of modern rice varieties to the field population of brown planthopper (BPH). The researchstudied BPH settling preference, numbers of laid eggs, and functional plant loss index (FPLI) of resistant and susceptible ricevarieties. The results showed BPH were less settle and laid fewer eggs on resistant varieties. BPH significantly settled longeron TN1 than other varieties after 24 hours. The numbers of eggs laid on rice resistant varieties (Inpari 13, Inpari 31, Inpari 33,RH, and PTB33) were fewer compared to TN1. FPLI value in TN1 was the highest among the tested rice varieties. Inpari 13 hadbetter resistance to BPH compared to Inpari 31 and Inpari 33. In managing BPH in endemic areas, we recommend Inpari 13,Inpari 31, and Inpari 33 to be planted in rotation.

Abstract

Consumption of high nutritional is increasing; therefore, it is necessary to develop pigmented trice variety with high yield, good adaptability, and good grain quality favored by consumer such as soft texture. The development of aromatic rice variety includes crossbreeding, selection, yield trials, resistance test to pest and diseases, physico-chemical properties assay, analyzing of minerals contents and anthocyanin which were done consecutively during 2012 to 2016. The results showed that a promising line of BH39D-MR-11-1-1-6 revealed consistent grain yield in 16 multi-location yield trials both in the dry season and the wet season in average 6.78 t/ha dan 5.35 t/ha, respectively. The line demonstrated its yield potential of 10,67 t/ha, mid-resistance to biotype 1 of brown planthopper, resistance to pathotype III and mid-resistance to pathotype IV and VIII of bacterial leaf blight, and mid-resistance to four races of rice blast (race of 033, 073, 133 and 173). This line had relatively comparable iron content with the check variety of Inpari-5 Merawu but higher in zinc content compared to other lines tested. The dehulled rice was red and contains a high total phenolic compound amounting (5,743 mg AAE/100 g), and its texture was soft and fragrance. The BH39D-MR-11-1-1-6 has been released as new rice variety named as Inpari Arumba and had a great potential to become a national specialty rice choice.
