Photosynthetic ability in terms of CO_2 exchange rate and leaf area, dry matter accumulation(dry weight)and other important growth components along with yield and yield contributing characters in two F_1 hybrids of Akebono × Chiyonishiki(A×C)and Zenith × Akebono(Z×A)were studied. The photosynthetic rate at the flowering stage was lower than that at the panicle initiation stage in all the inbred parent cultivars and F_1 hybrids. Heterosis in photosynthetic rate was higher at the panicle initiation stage than that at the flowering stage. Pre-anthesis leaf area in the F_1 hybrid was significantly larger than that in the parent cultivars. However, the post-anthesis decline in leaf area was more rapid in the F_1 hybrids than in the parent cultivars and its magnitude was the highest in the F_1 hybrid of Z × A which was tall having long and curved panicles. Pre-anthesis dry matter accumulation in both hybrids was significantly higher in the F_1 plants than the parental cultivars, but post-anthesis dry matter accumulation in the F_1 hybrid was lower than the mid-parental value in Z × A. The degree of heterosis in grain yield varied with the hybrid combination, an average heterosis being 1.03. Heterosis in grain yield was closely associated with heterosis in harvest index. |
