By two-factor( cultivation mode and genetic basis) randomized block design,under3 planting modes( direct seeding,2-3 leaf transplanting stage and 4-6 leaf transplanting stage),plant survival rate and pollination success rate of haploid induced by the genetic selection of 5 No Reid × Dom were studied to clarify the effects of different planting modes on survival and success rate of pollination. The results showed that survival rate of haploid at 2-3 leaf transplanting stage was the highest,the average of which was 81. 70%,and pollination success rate reached an average of11. 33%; average survival rate of haploid at 4-6 leaf transplanting stage was 79. 12%,and pollination success rate was the highest,the average of which was 11. 34%; survival rate of haploid was the lowest under direct transplanting,with an average of 72. 47%,and pollination success rate was the lowest too,the average of which was 10. 30%. The experimental study showed that seedling transplanting after haploid treatment could improve seedling survival rate and pollination success rate of haploid effectively.
