Character Association And Path Analysis in Inter-Racial Hybrids in Rice (Oryza Sativa L.)
The studies on the correlation of the traits and their relative direct and indirect effects on yield are important, as they are helpful to adopt suitable selection procedure for yield improvement in inter-racial breeding programmes. In the present study, 15 wide compatible genotypes (11 tropical japonicas and four indicas) were crossed with six non-wide compatible genotypes (three each of indic...
متن کاملCharacter Association and Path Analysis in Rice (Oryza sativa L. ) Genotypes
The present study was undertaken with the objective to determine the nature and magnitude of variability, degree of association between yield and it`s component characters and their direct, indirect effects on grain yield in rice (Oryza sativa L.). Thirty three genotypes were evaluated for identifying their efficiency with respect to 20 yield and quality traits. High heritability with high gene...
متن کاملAssociation mapping for yield and grain quality traits in rice (Oryza sativa L.)
Association analysis was applied to a panel of accessions of Embrapa Rice Core Collection (ERiCC) with 86 SSR and field data from two experiments. A clear subdivision between lowland and upland accessions was apparent, thereby indicating the presence of population structure. Thirty-two accessions with admixed ancestry were identified through structure analysis, these being discarded from associ...
متن کاملAnalysis of QTLs for panicle exsertion and its relationship with yield and yield-related traits in rice (Oryza sativa L.).
Panicle exsertion (PE) is an important morphological trait that is closely associated with spikelet fertility and grain yield. To understand the genetic basis of PE and its relationships with yield and yield-related traits, a recombinant inbred population consisting of 240 lines derived from a cross between an Indica cultivar 'Kasalath' and a Japonica germplasm 'TD70', was studied over two year...
متن کاملStudies on root traits for drought tolerance in rice (Oryza sativa L.) under controlled (PVC pipes) condition
Rice (Oryza sativa L.) is the most important food crop of the world; but drought stress is a serious limiting factor to rice production and yield stability in rainfed areas. In order to design an efficient breeding program for synthesis of new varieties with virtues of drought tolerance and high yielding ability, it is necessary to identify potential parents that combine well for both yield and...
