There is little doubt that genotypic differences in CAP exist in soybean and there is good evidence that CAP is a quantitatively inherited trait. Substantial evidence shows a positive relationship between CAP and seed yield, particularly in determinate genotypes. The latter relationship accounts for a maximum of about 50 percent of the yield variability among genotype. These responses collectively imply that it would be possible to select for high yields indirectly by selecting for high CAP. However, obtaining accurate measurements of CAP on hundreds of soybean lines is a formidable and expensive task (Boerma and Ashley, 1985; Shibles, et al., 1987). Therefore, the value of selecting for increased CAP to increase seed yield will be determined by adaptabilityof current and future technology to the identification of indices which project CAP of field soybean canopies (Boerma and Ashley, 1982). |
