Relationship of milled grain percentages and flowering-related traits in rice Academic Article uri icon

abstract

  • The economic value of harvested rice is determined by the grain yield and the percentages of head rice (at least 3/4 the length of a head or kernel) and total milled rice. This study was conducted to determine the effects of flowering-related traits such as duration of flowering, rate of flowering, heading, and duration from heading to maturity on head rice and total milling percentages of rice. Flowering data, gathered for two years from 105 long grain rice genotypes grown in Beaumont, Texas were analyzed for their effects on and relationship with milling traits. A positive linear relationship was obtained for rate of flowering and the duration from heading to maturity but negative for duration of flowering and days to heading. Genotypes with early heading had relatively shorter flowering durations, and genotypes with shorter flowering duration had higher head rice and total milled rice. A faster rate in attaining 100% flowering and more days from heading to maturity were favorable in increasing head rice and total milled grains. The duration from the start of flowering to heading or to 100% flowering can be used in the evaluation and selection for high head rice and total milled rice percentages in rice.
