Abstract
Twenty one coloured and white-skin garlic genotypes which were collected from different places of the Middle Egypt were used in the first experiment to study and evaluate their performance and growth behavior. Cloves of the 21 genotypes were planted in foam trays filled with beat moss and vermiculite soil 3:1 v/v (without chemical fertilizers). At 45 day old, seedlings of the twenty one (ten coloured and eleven white skin) garlic genotypes were evaluated for their growth performance in the foam trays. Also, correlations among different growth characteristics e.g., root length, shoot length, number of leaves/plant, plant height, and biomass weight along with yield/plant at harvest time in open field (180 days after cloves plantation) were studied.
Results showed that the genotypes differed significantly in their growth characteristics and yield. The coloured garlic genotypes showed the highest values of most of the studied characters. Moreover, the correlation coefficient values were positive and significant or high significant among most of the studied traits meaning these characteristics are correlated to each other except for number of leaves/plant with whole plant weight. The simple correlation coefficients values between root weight, shoot weight and biomass weight/plant at 45 days old under laboratory conditions and yield per plant under field conditions for the ten coloured and eleven white genotypes were positive and significant.
