Abstract	Possible unfavourable influence of sterility inducing cytoplasm on physico-chemical grain quality traits in rice hybrids is one of the important concerns hindering the large-scale adoption of hybrid rice technology. Produce from 23 pairs of CMS line × restorer (AF1) and maintainer line × restorer (BF1) cross combinations carrying different cyto-sterile sources (WA, ARC, Mutagenized IR 62829B and Kalinga I) was compared for various grain and cooking quality traits. The milling recovery in rice hybrids was not influenced by the sterile cytoplasm. For kernel dimensions before and after cooking there were both favourable and unfavourable cytoplasmic effects, which varied in magnitude depending upon the sterile cytoplasm and parental combinations. Similar results were obtained for kernel elongation and gelatinization temperature. The most widely used WA cytoplasm had minimum instances of unfavourable influence. In general, the cytoplasmic influence was found to be highly cross-specific and depended on the nuclear background of CMS line and fertility restorer. Availability of alloplasmic CMS lines carrying different cyto-sterile sources in the same nuclear background would help in ascertaining the cytoplasmic influence in a more comprehensive manner.
