204 Research Hortic. bras., Brasília, v.37, n.2, April-June 2019 I n genetic improvement programs, there is a constant search to bring together in a single individual several characters of interest, to meet both demands, of the producer and the consumer. In this scenario, garlic cultivation ( Allium sativum ), in addition to obtaining greater total bulb yields, is also sought for quality for the market with a high marketable yield that considers the diameter of the bulb larger than 37 mm (Brazil, 1992). Garlic has been described as a sterile species or as a typical apomictic obligatory plant (Etoh, 1980), being propagated asexually, by means of cloves taken from the base of the plant, or by aerial cloves of the inflorescences (Pooler & Simon, 1993). Therefore, the classic improvement of this vegetable, through crossings to increase the genetic variability, has been discarded, being possible the selection on already existing materials, of germplasm banks, identifying the superior ones for specific conditions of each culture environment (Souza & Macêdo, 2009). In addition, selecting superior garlic genotypes is not an easy task, since bulb yield has a complex genetic action and, in order to study it properly, one must evaluate the environment and other characteristics that may contribute to production (Chotaliya & Kulkarni, 2017). The use of statistical tools can aid in such evaluations, such as correlation ANDRADE JÚNIOR, VC; GUIMARÃES, AG; FIRME, TD; COSTA, AAA; COSTA, MR; LOPES, TK; SOUZA, RJ; RESENDE, FV. 2019.

Thus, the objective of this work was to perform genotypic, phenotypic correlations and path analysis under commercial yield of garlic bulbs, depending on morphological and agronomic variables. The experiment was carried out in 2017 at the Universidade Federal dos Vales do Jequitinhonha e Mucuri and Universidade Federal de Lavras, using ten garlic genotypes, eight trials and two commercial cultivars, Caçador and Jonas. We evaluated: plant height; number of leaves, total bulb number; total bulb mass, total bulb yield, marketable bulb yield and number of cloves per bulb. The genotypic and phenotypic

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
