Droughtatanystageof corngrowthgreatly affectscropproductivity. Increasedmaizeproduction canbe solvedbyusingdrought tolerant varieties. The purposeofthis studywas to determinethe responseof hailsomaklonaR1 plantsin vitro selection result againstdrought stressandevaluate thephysiologicalcharacteristicsof droughttolerantplantssomaklon.
