Research Abstract

Spinach (Spinacia oleracea L.) has high nutritional value but accumulates large amounts of oxalate, which reacts with calcium, inhibiting its absorption and forming urinary stones in humans. In this study, low-oxalate spinach mutant was induced through ethyl methane sulphonate (EMS). The mutant plants grew weakly and bolted earlier under natural long day in spring. The low-oxalate character was controlled by single recessive gene. Low-oxalate, vigorously growing and bolting-resistant line was developed by crossing with a late-bolting commercial cultivar.
