EVALUATION OF SINGLE AND THREEWAY CROSS HYBRIDS OF PEARL MILLET

Abstract

Hybrids of five altered male sterile lines with 0.5 transferred genome (TG)(81A x 3383B, 81AxPb305B, 3383A x 81B, Pb 302A x Pb 305B, Pb 403A x Pb 405B) and four altered made sterile lines with 0.75 TG level (SIA x 3383B2, 3383A x 81B2, Pb 302A x Pb 305B2, Pb 403A x Pb 405B³) along with single cross hybrids of respective inbred male sterile lines and checks were evaluated during 1988-89 kharif and rubi. Significant differences were observed among the entries for all the characters in both the seasons. The three way cross (81A x Pb305B) x PIB 2231P out yielded the check X.5. The hybrids (3383A x 81B) x PIB 2231P and (Pb403A x Pb405B) x PIB 2231P recorded significantly higher yield than single crosses of their respective original A lines. The hybrids of altered A lines with 0.5 TG were found to be superior than the hybrids of respective altered A lines with 0.75 TG. Superiority of three way crosses over single crosses was observed which offered scope for the production of three way hybrids.
