  • Title: [Quantitative analysis for inheritance of quality characters in indica hybrid rice].
    Author: Ao Y, Xu CW, Mo HD.
    Journal: Yi Chuan Xue Bao; 2000; 27(8):706-12. PubMed ID: 11055123.
    Abstract:
    Nine quality characters of 3 sterile lines, 10 restorers and their 30 indica hybrid rice by NC II genetic design were studied. The results showed as follows: (1) No genetic segregation occurred in F2 grains in grain length, grain width, grain weight, brown rice% and head rice%, which indicated these traits are completely controlled by maternal plant genotypes. (2) Significant genetic segregation occurred in F2 grains in chalkiness score, amylose content, gelatinization temperature and gel consistency, which indicated the genetic expression of these traits is mainly controlled by endosperm genotypes. (3) The quality characters have relatively high heritabilities except brown rice % and chalkiness score. The genetic variation of quality characters was mainly caused by additive effect except grain weight.
