The Inheritance of Poly - caryopsis and It’s Linkage Relations in Rice

A poly-caryopsis was found in one family among the 19 families of the BC₁F₂ of the rice cross between Japonica cultivar Suwon 224 and Javanica cultivar Malagkit Sinaguing. All of the plants derived from the poly-caryoptic plant showed poly-caryopsis. The ratio of poly-caryopsis in the poly-caryoptic plant varied from 71.5 to 85.7%. The single caryopsis was found more on top than on basal part of rachilla in a panicle of the poly-caryoptic plant. The poly-caryopsis derived from wx154-134-40 inherits as single recessive character and it is linked with long empty glume (g) belonging to the linkage group IV, where the recombination value calculated was 30.0±5.2%. The gene symbol pc was suggested for the poly-caryopsis derived from wx154-134-40.
