Expression of resistance in rice hybrids to Pyricularia grisea. Repositório Alice
PRABHU, A. S.; GUIMARÃES, E. P.; FILIPPI, M. C.; ARAUJO, L. G.; CUTRIM, V. A..
Foram avaliados 39 híbridos de arroz (Oryza sativa) desenvolvidos a partir das linhagens 046I e IR 58025A com macho esterilidade genético citoplasmática derivado do citoplasma WA e seus restauradores, para resistência vertical a Pyricularia grisea. Os testes foram realizados em viveiro de brusone e em condições artificiais de inoculação com dois patotipos, em casa de vegetação. Em viveiro de brusone, todos os híbridos apresentaram reação suscetível variando de 5 a 9 em uma escala de 0 a 9. Reações compatíveis e incompatíveis à brusone nas folhas foram observadas para os dois patotipos IC-1 e IB-45, em inoculações controladas. A maioria dos híbridos foi resistente quando o restaurador utilizado como pai foi resistente. Entretanto, sete dos 25 híbridos F1...

Expression of resistance in rice hybrids to Pyricularia grisea Trop. Plant Pathol.
PRABHU,ANNE S.; GUIMARÃES,ELCIO P.; FILIPPI,MARTA C.; ARAUJO,LEILA G.; CUTRIM,VERIDIANO A..
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...

HYBRID RICE AND ITS IMPACT ON FOOD SECURITY AND THE PATTERN OF GLOBAL PRODUCTION AND TRADE AgEcon
Durand-Morat, Alvaro; Wailes, Eric J.; Chavez, Eddie C..
The hybrid rice technology is one of the many ways in which productivity of scarce resources devoted to rice production could be enhanced, with the consequent alleviation of food insecurity. The findings of this study show that the hybrid rice technology has so far made some sizable contributions to per-capita availability of rice in adopting countries with marginal spillover effects to other regions. However, at forecasted population growths, a massive intensification of adoption would be needed to maintain per-capita availability of rice at baseline levels. But even with adoption rates climbing significantly, much higher equilibrium prices are expected, which will represent a challenge for the hungry in many parts of the world. While hybrid rice has the...

Mapping of quantitative trait loci for thermosensitive genic male sterility in indica rice. Repositório Alice
ALCOCHETE, A.A.N. de; RANGEL, P.H.N.; FERREIRA, M.E..
The objective of this work was to select and use microsatellite markers, to map genomic regions associated with the genetic control of thermosensitive genic male sterility (TGMS) in rice. An F2 population, derived from the cross between fertile and TGMS indica lines, was used to construct a microsatellite-based genetic map of rice. The TGMS phenotype showed a continuous variation in the segregant population. A low level of segregation distortion was detected in the F2 (14.65%), whose cause was found to be zygotic selection. There was no evidence suggesting a cause-effect relationship between zygotic selection and the control of TGMS in this cross. A linkage map comprising 1,213.3 cM was constructed based on the segregation data of the F2 population....
