Abstract：Nanou garlic is a closely related species of garlic．Understanding its developmental
characteristics and growth dynamic rule can provide references for the fertility mechanism，industrial
development and germplasm innovation of cultivated garlic．This experiment conducted analysis and
comparison on phenotypic characters of Nanou garlic sexual propagated progeny strains．The result indicated
that the plant height，plant width，leaf length of Nanou garlic progeny strains during the phase taking
vegetative growth as the main object，showed a developmental pattern of slow growth in the early stage，rapid
growth in the middle stage and slow growth in the later stage．While，at the end of growth stage its plant width
decreased first then rose again．As a whole，all strains grew vigorously between April 16-April 20，a critical
period for the growth management of Nanou garlic．The variation coefficients of morphological traits ranged
from 19.56%-27.35%．That of relative chlorophyll content was 24.87%，of which the 8N540-11 strain with
excellent comprehensive phenotypic traits had better application prospect．
