Genetic Evaluation and Path Analysis in Garlic

Abstract

Garlic (Allium sativum L.) is an important crop grown and used as a spice or condiment throughout India. Among bulb crops, it is another foreign exchange earner for India as a good quantity of garlic is exported every year Therefore, for planned breeding pro-gramme to improve compound bulb yield potential, information on the nature and magnitude of variation in the avail-able material, association of characters with yield and among themselves and the extent of environmental influence on these traits is necessary. Further, if the number of variables is more, it becomes essential to measure the contribution ul various variables to the observed correla-tion and partition the correlation coeffi-cient into components of direct and indirect effects. With the above objectives in mind, an experiment was taken up to determine the extent of genetic variabi-lity, correlation coefficient and path coefficient analysis of the components uf bulb yield. The trial was laid out with nine cultivars of garlio having diverse origin in a randomized block design with three replications at College Farm during winter, 1978. The cloves or segments were dibbled at spacing of 15 cm from row to row and 7.5 cm within the rows. Observations were recorded on ten random plants in each replication for eix characters (Table 1). Statistical analyses were carried out according to standard techniques.
