Resumen
Basmati rice is an important staple food grain crop in the world. Basmati rice is an important export commodity among the food grains. The biotic and abiotic factors are adversely affected the Basmati rice but Basmati rice blast caused by Pyricularia oryzae Cavara (synonym Pyricularia grisea Sacc). The anamorph of Magnaporthe grisea (Herbert), is one of the most destructive and wide spread diseases as compared to other diseases of Basmati rice. It causes leaf blast, neck blast and panicle blast of paddy. This disease generally causes yield loss of 10-20 percent but in severe cases yield loss may reach up to 80 percent. Management of blast disease using healthy seed, resistance varieties, many biological controls like as T. harzianum, T. viride and P. fluorescens @10g/kg by seed treatment and foliar spray. The chemical control by fungicides such as carbendazim, tricyclazole, isoprothilane, tebuconazole, hexaconazole reduced leaf but not neck blast; on the contrary, tricyclazole was effective against neck blast and panicle blast.

Resumen
Rice blast, caused by Pyricularia grisea, was first found in California in 1996. Disease surveys have shown the blast disease is spreading at a moderate rate in California rice fields. Although no effective major resistance genes are known to occur in widely grown commercial California cultivars, there appear to be differences among the cultivars with respect to field susceptibility to the pathogen. P. grisea was recovered from rice crop residue and commercial seedlots which are suggested as possible sources of initial P. grisea inoculum in California rice fields. Examination of weather data indicates that environmental conditions in California rice-producing areas are permissive for rice blast but generally not optimal for epidemic development. Spore trapping determined that the majority of P. grisea conidia are generally not released until approximately 6:00 A.M. and would not have sufficient time for infection before leaf wetness periods end. Azoxystrobin showed positive results with respect to reduction of neck blast incidence and yield increases in small-plot and large-scale fungicide trials.

Resumen
[DIVERSITY AND THE SOURCE OF RESISTANCE GENE OF LOCAL RICE VARIETIES ON THE PATHOGENIC OF Pyricularia grisea CAUSE OF BLAST DISEASE]. Local rice varieties are known to have resistance or source of genes to pests even though their productivity yield is low. The pathogen of Pyricularia grisea is a cause of blast disease, which is one of the obstacles in rice production. The research aims to characterize the resistance of local rice varieties to the pathogen of P. grisea and to evaluate the virulence level of P. grisea pathogens against local rice varieties. A total of 100 local rice varieties and check varieties are susceptible and resistant namely Kencana Bali and Situ Patenggang tested their resistance to 4 dominant pathogenic of P. grisea i.e. races 033, 073, 133 and 173. Inoculation was carried out on stages 4-5 leaves or 18-21 days after seedling in a green house. The results showed a high genetic diversity of local rice varieties against pathogenic races 033, 073, 133 and 173. Based on the response of local rice varieties resistance i.e. moderately resistant (MR), resistant (R) and susceptible (S) to pathogenic races 033, 073 , 133 and 173 obtained 45 resistance response patterns. Cere Bereum varieties which are local rice varieties from West Java and Situ Patenggang resistant check varieties have a resistant response to 4 P. grisea pathogenic races used. A number of local rice varieties also show a resistant and moderately resistant response to the four pathogenic races used include Siam 11, Pare Siriendah, Menyan, Cere Manggu and Enud-Rawa Bogo. Local rice varieties Djedah and Padi Hitam (2) are local rice varieties that have a specific response of resistant or moderately resistant to race 173. Race 133 and 173 have higher virulence rates than those of races 033 and 073 on local rice varieties. The results of this study indicate that there is a great potential for the utilization of local rice varieties, as a source of resistance genes for blast disease for the assembly of rice varieties that are resistant to blast disease.

Resumen
Pyricularia grisea is a pathogenic fungus which causing rice blast disease that affected leaf, stems and rice panicles of rice plant. A possible option to reduce the use of synthetic chemical fungicide in managing the blast disease is by using plant natural active ingredients to inhibit the mycelial growth of Pyricularia grisea. This research evaluated the potential uses of bay leaf, tropical almond leaf, and kaffir lime leaf extract in inhibiting pathogenic fungus Pyricularia grisea. A Completely Randomized Design (CRD) with 3 replications and 4 treatments were used in this research. Work procedures included leaf extracts preparation, pathogenic fungi rejuvenation, growth media preparation and isolates plantation on PDA media. The parameter in this study was the diameter of the Pyricularia grisea inhibition zone. Data was analysed by analysis of variance (ANOVA) at 95% confidence interval with Duncan Multiple Range Test (DMRT) at 5% level (α = 0.05) as post hoc test if significant differences between treatments were detected using SPSS 16.0. The results of this study indicated that the highest concentration (100%) of each plant leaf extract was able to inhibit the mycelial growth of the pathogenic fungus Pyricularia grisea. The zone of inhibition of bay leaf extract was 1.77 mm, tropical almond leaf extract was 2.33 mm and lime leaf extract was 1.52 mm. The largest diameter of the inhibition zone was found on media with tropical almond leaf extract.

Resumen
Thirty-nine rice (Oryza sativa) hybrids and their restorers were assessed for vertical resistance to Pyricularia grisea in the rice blast nursery, and in artificial inoculation tests with two pathotypes, under controlled greenhouse conditions. The hybrids were developed from cytoplasmic genetic male sterile lines 046I and IR 58025A, derived from WA cytoplasm. In the rice blast nursery all hybrids showed susceptible reaction varying from 5 to 9. Compatible and incompatible leaf blast reactions of hybrids to two pathotypes, IC-1 and IB-45, were observed in inoculation tests. A majority of the hybrids were resistant when the restorer was resistant. However, seven of the 25 F1 hybrids exhibited susceptible reactions even when one of the parents was resistant to a pathotype. The partial resistance of 11 hybrids and their parents that showed compatible reactions to two pathotypes was analyzed. Differential interaction between isolates and genotypes was observed for partial resistance in relation to both disease severity and lesion number indicating the specific nature of partial resistance.

Resumen
Rice blast, caused by Pyricularia grisea (Cooke) Sacc., generally recognized as the most important disease of rice (Oryzae sativa L.) worldwide, was first found in the Sacramento Valley of California in 1996. Symptoms observed in commercial fields during September and October consisted mainly of darkened lesions at the panicle neck node and flag leaf collar. Many of the panicles with neck rot were partially filled or blank. Disease foci were irregular within fields and the most severely affected areas had approximately 50% of the panicle necks with symptoms. Initial identification of P. grisea was made by isolating the fungus from panicle neck nodes and leaf collars on potato dextrose agar. Subsequent identifications were made by placing symptomatic panicle neck nodes or leaf collars on moist filter paper in petri dishes to allow sporulation of the fungus. P. grisea was consistently recovered from these tissues and was identified by conidial morphology. A survey of over 500 rice fields in five Sacramento Valley counties was conducted in September and October 1996. Rice blast was confirmed in 33 commercial fields, which are spread over an area of approximately 460 km2 in Glenn County (27 fields) and northern Colusa County (6 fields). No blast was found in Butte, Sutter, or Yolo counties. P. grisea was recovered from cvs. M-201, M-202, M-204, M-103, M-401, S-102, L-204, and Calmochi-101 and several proprietary lines. To confirm pathogenicity of P. grisea, cv. M-201 was inoculated in the greenhouse 28 days after seeding with a suspension of 20,000 conidia per ml of sterile deionized water, covered with plastic bags for 2 days, and evaluated 7 days later. P. grisea isolates from cvs. M-201, M-202, and M-204 produced typical leaf and collar blast symptoms on inoculated plants, whereas control plants remained asymptomatic. P. grisea was consistently recovered from lesions on inoculated plants. No rice cultivars currently grown in California are known to have resistance to blast.

Resumen
The severity of the rice blast disease (Pyricularia grisea) of both leaf and neck varies with different environment and it becomes destructive under favorable condition. The leaf and neck blast resistance and susceptible interaction of 30 different tropical rice lines were evaluated under low-, mid- and up-land conditions of Chitwan district and classified on the basis of disease severity with respect to susceptible check, Masuli. Of them, 5, 10, 12 and 3 rice lines were resistant to leaf blast, moderately resistant, moderately susceptible susceptible, respectively. Similarly, for the neck blast nine lines were resistant, thirteen moderately resistant, seven moderately susceptible and one was susceptible. The progenies from Masuli/MT4 had the highest leaf and neck blast susceptible reaction, while the most of progenies from IPB (Irradiated Pusa Basmati), KalinghaIII_IR64, Radha 32_ KIII and Masuli_IR64 were resistant, and the most promising sources against leaf and neck blast resistance. Therefore, the progenies from these parents can be used in breeding the resistant variety. Key words: Pyricularia grisea, resistance, rice lines J. Inst. Agric. Anim. Sci. 27:37-44 (2006)
