Study Title: Grain development phenotypes from rice genotypes, SN and LGR (1000 grain weight, grain filling rate)
Description:
Start Date : Aug. 1, 2013
End Date: Sept. 1, 2013
Data Type: Phenotypic
Location : New Delhi
Description of experimental design : Long-grained and short-grained indica rice, LGR [66], and Sonasal (SN), respectively, were grown in the kharif season in the field conditions at NIPGR, New Delhi, India. Freshly harvested seeds of 0, 1, 2, 3, 4, 7, 10, 13, 18, 21, and 29 DAP were collected in 30% ethanol. Images of husked and dehusked seeds of SN and LGR were captured at × 4 magnification under a stereozoom microscope (AZ100, Nikon; Japan). Grain length and width were quantified per seed by taking average of 100 seeds using WinSEEDLE™ software (Regent Instruments Inc.; Canada). One thousand-grain weight was measured in biological triplicates. Grain filling rate was estimated by measuring fresh weight of 15 seeds in triplicates from each DAP after removing stalks and awns. The measurements from each DAP constituting a stage were added to obtain the weight of 15 seeds/stage.
