Abstract

Abstract:

Agronomic characters and biochemical matter contents in flower buds and leaves of the two CMS lines 9704A and 8214A , of their each maintainers and F1 hybrids for sterile line ×restorer and maintainer ×restorer in pepper were studied. Results showed that differences in plant height between the two kinds of hybrids reach significant level . POD activity in sterile linespflower buds and leaves is higher than that in maintainersp, still the activity in hybrids for sterile line ×restorer is significantly , even very significantly higher than that in hybrids for maintainer ×restorer. Sterile lines contain less free praline than maintainers in the flower buds , and the content in hybrids for sterile line ×restorer is significantly , even very significantly lower than that in hybrids for maintainer ×restorer. IAA content in sterile linespflower buds and leaves is lower than that in maintainersp. ABA content in sterile linespleaves is higher than that in maintainersp, but the vise versa in their flower buds. No obvious laws are found in the effect of the male sterile genes on content change of IAA , ABA and ZRs in hybrids yet .
