A study of the characteristic morphology of flowers and pollen in vegetable life phase, all 7 strains of vegetables that phase 6 (23-6, 11-8, 11-7, 9-3, 10-8-7, 142-157, 6-5, and-7-12) features flowers and pollen usual lettuce cultivars from China, phase characteristics of gaysorn male barren from to determine the life of the pollen morphology of political behavior, in combination with the flowers can be used as a basis to see how a vegetable that resembles the phase of normal male barren and gaysorn. For develop and breeding to create varieties of hybrids to continue to use the monitoring features of the hybrids from the barren male behavior, gaysorn hosts species.
