Grey Relational Analyses between Biochemical Matter Contents and Agronomic Characters of Hybrids in Pepper

The correlativity between agronomic characters and yield per plant and between biochemical matter contents in flower buds and leaves and agronomic characters of CMS hybrids were estimated in pepper by using the method of grey correlation degree. Results showed that the magnitude on grey correlation degree between various agronomic characters and yield per plant was plant spread, plant height, fruit length, fruits per plant, weight per fruit, the first flower node, fruit width and branches per plant. The magnitude on grey correlation degree between various biochemical matter contents in flower buds and agronomic characters was soluble sugar, soluble protein, POD activity, ABA, IAA, free proline and ZRs. The order in leaves was soluble sugar, POD activity, free proline, ABA, IAA, ZRs and soluble protein.
