Analysis of Yield Components and Aroma of Small Grain Aromatic Rice (Oryza sativa L.) in Bangladesh
The study was conducted to evaluate the extent of variability among the small grain aromatic (SGA) rice (Oryza sativa L.) genotypes for yield and yield components. Twenty four popular SGA rice genotypes were evaluated for yield and yield contributing characters in BRAC Agricultural Research and Development Centre, Gazipur, Bangladesh. BRRI dhan34 was used as check variety. Highest grain yield p...
متن کاملCorrelation and Path Coefficient Analysis for Yield and Yield Components in Blackgram (vigna Mungo (l.) Hepper)
Correlation coefficient and path analysis studies was conducted with eight parents and their 28 F1 crosses for twelve component characters including seed yield and revealed significant positive association of pods per plant, harvest index and clusters per plant with seed yield in parental generation whereas in F1 generation, significant positive association of clusters per plant, pods per plant...
متن کاملEpistasis for three grain yield components in rice (Oryza sativa L.).
The genetic basis for three grain yield components of rice, 1000 kernel weight (KW), grain number per panicle (GN), and grain weight per panicle (GWP), was investigated using restriction fragment length polymorphism markers and F4 progency testing from a cross between rice subspecies japonica (cultivar Lemont from USA) and indica (cv. Tequing from China). Following identification of 19 QTL affe...
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 کاملidentification of gene loci (qtls) controlling grain yield and yield components in rice (oryza sativa l.)
to identify qtls controlling grain yield and yield components, an f2 population consisting of 188 plants derived from the cross between two rice pure lines, binam and kadous, were grown in research field of faculty of agricultural sciences, university of guilan, rasht, iran, in 2008, and were recorded for 9 important traits related to grain yield. to construct linkage map, 85 marker of ssrs and...
