Abstract
In this study, we conducted to identify predictive parameters affecting the head rice ratio for developing high quality rice cultivar adaptable to the early-transplanting cultivation. The recombinant inbred lines (RILs) population from a cross between the parents of Pungmi and Koshihikari was used for test materials. Variations were observed in most of the measurements, eg culm length (ranging from 51.0 cm to 97.0 cm), amylose content (14.0~20.1%), protein content (5.2~7.4%), pasting properties (peak viscosity, 227.2~309.8 RVU) and head rice ratio (67.7~96.7%). Significant correlations between head rice ratio versus culm length (0.443) and head rice ratio versus protein content (-0.458) were detected in RIL population. However, culm length was negatively related to lodging tolerance. In order to develop a commercially suitable cultivar, selection for short culm and high head rice ratio of rice grains with physiochemical properties such as protein content, amylase content and taste value should be considered. This results can be used to increase the efficiency of breeding program for developing a new early-maturing rice variety adaptable to early transplanting cultivation in Korea.
