Interactions amongst Grain Variables in Various Dwarf Dry Bean (Phaseolus vulgaris L.) Cultivars

Common bean ( Phaseolus vulgaris L.) is an important leguminous crop. Seed variables such as protein, oil, cellulose, ash, nitrogen-free extract, testa and moisture contents and the thousand-seed weights of seven bean cultivars currently cultivated in Turkey, namely, A-111 Pinto, Çalı, Yunus-90, Eskişehir-855, Şehirali-90, Karacaşehir-90 and Romano, were analysed in the laboratory with respect to their effects on the quality of bean seed grown under Central Anatolian ecological conditions. Statistically significant variations were found by ANOVA amongst the cultivars for all the variables examined, except the ash content of the seeds, and different groups were obtained by Duncan's multiple range test. Correlations amongst the variables as well as their direct and indirect effects on protein content were also calculated using the correlation and path coefficients analyses, respectively.
