Intact cooked kernel is characteristic of Basmati and good cooking rices. No scale has been developed to classity it at intemationallevel though scales have been developed for various grain quality parameters. Cooked kernel appearances have not been subjected to inheritance studies. Till now only method of getting intact lines is selection. In the present study 307 RILS (F9) of cross Bas 370 and ASD 16 developed through SDS (single descent selection) were subjected to henotyping for grain and cooking quality traits and cooked grain appearance. Both the parents had nearly intact c, oked grains, while the F9 population showed various types of split grains and transgressive variation. The data g~nerated during this study indicate that the population differs in the extent of split kernels and this criterion may prove useful in identifying markers for intactness which can be used for genotyping the RILs for mapping of QTLs' for this important quality trait.
