Asociaciones entre clones y anormalidades morfológicas en ajo "tipo colorado" (Allium sativum L.).

With the object to detect the influence of the genotype in the presence of morphologic abnormalities, a sample of 200 took cloves of each of 7 clones of red garlic was taken included in an experimental essay in blocks completely randomized with 4 repetitions, in only one environment of expression. In every clone there were calculated the proportions of normal bulbs, pear-like bulbs, onion-like bulbs and double bulbs cloves. In the normal bulbs the distribution of calibres measured up. The proportions of abnormalities were compared between the clones. A clone differed (p < 0.05) of the remaining ones for not possessing malformations and a low average calibre presented. Using the obtained information as a whole, an analysis of principal components and of the clustering was made. The euclidea average distance and the method of average linkage was used. The first two axes of the analysis of the principal components represented 74% of the variation of the data. The obtained information allowed to assemble 3 groups of clones because of its association to calibres and morphologic abnormalities. The first group formed by a clone without abnormalities and with major proportion of calibre 4 and 5; the second one, formed by four clones with the presence of onion-like bulbs and the third one, of two clones associated with the pear-like bulbs, doubles bulbs cloves and of calibres 6. The influence of the genotype was demonstrated in the frequency of morphologic abnormalities. [ABSTRACT FROM AUTHOR]
