Genetics of Protein per Grain in Rice

Abstract:

Seed protein content is usually expressed as percent brown (dehulled) rice protein (BRP). This trait is highly influenced by environment and, hence, its expression is complex. It has been suggested that instead of considering BRP, it would be effective to use as selection criterion the actual protein available per grain (PPG) since the latter is less influenced by environment. However, information on inheritance patterns of PPG in rice is scanty.

 

We studied gene action and estimated general combining ability (GCA) using six parents (IR50, ADT37, ADT41, Duansan, TKM6, and ADT39) and 30 hybrids generated through full diallel mating.
