ICRISAT had developed and disseminated a large number of male-sterile lines (A-lines) and their maintainers (B-lines) over the years, which had been characterized for key agronomic traits and downy mildew resistance in the years they were developed, but not in the common environments. Ninety-nine of these A-lines and their counterpart B-lines developed during 1981–2004 were evaluated for 26 mor...

HE origin, fertility, and identifying vegetative characteristics associated with some monosomics of Upland cotton, Gossypium hirsutum L., have been described by BROWN and ENDRIZZI (1963). The monosomes were highly stable and n-1 gametes were transmitted with a high frequency through the egg, but very rarely through the pollen. ENDRIZZI and BROWN (1963) have obtained the cytogenetic data that id...

The present investigation has been undertaken in sweet corn to carry out the combining ability analysis and to estimate heterosis of yield and yield contributing characters. Eight divergent parents were selected and crossed in diallel fashion excluding reciprocals during kharif, 2010. The resulting 28 crosses along with parents and a standard check Sugar 75 and Madhuri were evaluated in Randomi...

Twenty hybrids were produced using five CMS lines viz., BRRI3A, BRRI9A, IR73328A, BRRI10A and IR78355A and four restorers viz., BRRI12R, BRRI13R, BRRI14R and BRRI15R following line x tester mating design to find out the best combination (s) in respect of their combining ability effects among the parents and hybrids at BRRI, Gazipur, Bangladesh from July 2008 to May 2009. Data were recorded from...

Many vocabularies and ontologies are produced to represent and annotate agronomic data. By reusing the NCBO BioPortal technology, we have already designed and implemented an advanced prototype ontology repository for the agronomy domain. We plan to turn that prototype into a real service to the community. The AgroPortal project aims at reusing the scientific outcomes and experience of the biome...

The present study aims to determine spectral bands that are best suited for characterizing rice agronomic variables. The data for this study came from ground-level hyperspectral reflectance measurements of rice at different stage. Reflectance was measured in discrete narrow bands between 350 and 2500 nm. Observed rice agronomic variables included leaf area index (LAI), wet biomass (WBM includin...
