FERTILITY RESTORATION CAPACITY OF FOUR RESTORERS IN HYBRIDS WITH CMS LINES HAVING TRITICUM TIMOPHEEVI CYTOPLASM

Published on

Fertility restoration capacity of four exotic Rf·sources (W 8156, 3401/478466, PE/YQ and
R3-401) in five eMS lines (msHD 2204, msHD 2260, msHP 1102, msUP 368 and msWH 157)
with T. timopheevi cytoplasm and their reciprocal crosses was studied in two sets during
1983 and 1984. The set I included A X R and set 11 R X B crosses. The significant differences
in the fertility restoration capacity of all the Rf·sources studied were observed in both the
years. R X B crosses showed better seed set than their respective A XR crosses. During both
crop seasons msHD 2204 X PElYQ in set I gave the highest seed set while msUP 368 gave
consistently high seed set with all restorers.
