Abstract:

Garlic is the second most important bulbous vegetables after onion and used as a spice and flavoring agent for foods. The present study was carried out at the Horticultural Research Centre, College of Agriculture, S.V.P. University of Agriculture and Technology, Meerut (U.P), India. The results revealed that more than 75% of diversity of the total 131 garlic germplasm is present in first 4 principal components out of 12 and they had Eigen values recorded more than 1. The first PC explained characters viz., plant height, pseudostem height and diameter, polar or equatorial diameter of bulb, bulb weight plant-1and number of cloves bulb-1 (NCB) positively related to bulb yield. In case of PC2, characters like PH, PsH, EDB, NCB showed positive correlation. Bi-plot shows that there is a lot of variability present in the studied genotypes. The genotypes viz., K1, TG-F1, PG-20, GHC-1 and punnur local were identified as the best genotypes. Therefore, the above-mentioned variables might be taken into consideration for effective selection of parent’s in genetic improvement program for broadening the genetic base in the population as well as to develop elite garlic lines.
