| Data from the final phase of variety trials, covering a wide range of agro-climatic conditions, were examined to study the relationships between the v arious crops in the seven years cropping sequence generally adopted in Mauritius. Correlation coefficients between individual crops in a cycle ranged from low (less than or equal to 0.44) between plant cane and individual ratoons to moderate (less than or equal to 0.66) between individual ratoon crops, and with relatively high standard errors. In contrast, correlation coefficients between individual crops in a cycle and their cumulative values remained high in all environments, particularly so with ratoons (greater than 0.72), the standard errors being low. Plant cane seems to distinguish itself from ratoons which are more closely related to one another. Correlations established between pooled values of plant cane and early ratoons, which simulated the crop cycles adopted at different stages of selection, with pooled values of older ratoons, revealed the higher efficiencies of pooled values based on four crops as opposed to two or three in selecting for ratooning capacity. More considerations should be given to ratoon d ata during earlier selection stages to select for ratooning capacity. | |
