Abstract

Forty five aromatic hybrid rice combinations were produced using five basmati CMS and nine new Egyptian basmati restorers following line x tester mating design. This study aims to find out the best aromatic hybrid combinations in respect of their heterosis over the mid-parents (MP), better-parent (BP), the best inbred check variety Giza Basmati 201 and Basmati hybrid check EBHR11, for nine agronomic and yield traits. Hybrids with a yield advantage over the highest yielding inbred and hybrid check variety were considered as promising. Among 45 aromatic hybrid rice combinations evaluated, ten of them were most promising with mean performance of high grain yield ranging from 13.77 t/ha  for Sakha Basmati 13A x EBR2 to 13.98 t/ha for Sakha Basmati 13A x Giza Basmati 201 with an average of 13.874 t/ha. The yield advantage values over best local inbred check Giza Basmati 201 ranged from 3.060 to 3.260 t/ha with superiority of 27.71 to 30.45%, respectively.
