The purpose of this study was to discuss the practical usefulness of the discrimination of indica and japonica cultivar groups based on the morphology of silica bodies from motor cells in rice (Oryza saliva L.). The effects of nitrogen levels on the morphology of silica bodies from the flag leaf were investigated. Two indica varieties, "T-153" and "T-160" and a japonica variety, "T-708" were used and cultivated in pot scale (l/5000a). Nitrogen treatment was divided into three levels of 20 gm-2, 10gm-2, and 5 gm-2 and they were applied when the rice plants had 1.5-2.0 in remaining plant age in number of leaves (corresponding to 15 to 20 days before heading). The result showed little effect of nitrogen level on the morphology of silica bodies. No effect of nitrogen level was observed on the discrimination of indica and japonica cultivar groups based on the morphological characters of silica bodies, although the discriminating scores were slightly changed.

The effects of nitrogen levels on the morphology of silica bodies from the flag leaf were investigated. Two indica varieties, 'T-153' and 'T-160' and a japonica variety, 'T-708' were used and cultivated in pot scale (1/5000a). Nitrogen treatment was divided into three levels of 20 gm-2, 10 gm-2, and 5 gm-2and they were applied when the rice plants had 1.5-2.0 in remaining plant age in number of leaves (corresponding to 15 to 20 days before heading).

Genetic Analysis of the Morphology of Silica Bodies from Motor Cells in Rice (Oryza sativa L.)

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Japanese Society of Breeding
Genetic analysis of the morphology of silica bodies from motor cells in rice (Oryza sativa L.) was conducted by examining an F_2 population and a set of 3×5 NCII diallel crosses. Segregation for the four morphological characters-vertical length, horizontal length, Iateral length and shape coefficient (b/a)-of silica bodies in the F_2 population showed a countinous and a wide distribution exceeding the ranges of the two parents (Fig.2), suggesting that the morphological characters of silica bodies were quantitative and controlled by several genes. In the NCII diallel analysls, the heterogenelty of W'r+1/2Vr between arrays was not significant for all the morphological characters but b/a, and the heterogeneity of W'r-1/2Vr was not observed for all the characters tested (Table 4). The regression coefficients of W'r on Vr were nearly 0.5 but significantly different from zero (Table 5), indicating that the shape of the silica bodies was controlled by an additive-dominance genetic system. The heritabilities in a broad sense for the four characters were in the range of 0.43-0.73 and those in a narrow sense in the range of 0.29-0.54 (Table 6).

Genetic analysis of the morphology of silica bodies from motor cells in rice (Oryza sativa L.) was conducted by examining an F 2 population and a set of 3 x 5 NC II diallel crosses. Segregation for the four morphological characters-vertical length, horizontal length, lateral length and shape coefficient (b/a)- of silica bodies in the F 2 population showed a countinous and a wide distribution exceeding the ranges of the two parents (Fig. 2), suggesting that the morphological characters of silica bodies were quantitative and controlled by several genes. In the NC II diallel analysis, the heterogeneity of W'r+1/2Vr between arrays was not significant for all the morphological characters but b/a, and the heterogeneity of W'r-1/2Vr was not observed for all the characters tested (Table 4).
