‘Punjab Gaurav’ and ‘Punjab Sartaj’: Tomato varieties for polynet house cultivation

Abstract

Tomato (Solanum lycopersicum L.) is a versatile vegetable grown throughout most of the world under protected and open field conditions. It is one of the most sensitive crop plants and its production is often constrained due to various biotic and abiotic stresses. In north Indian plains, tomato grown in the open experience extreme weather conditions, i.e. sub-optimum temperature in January- February and extreme high temperature in May-June. Generally, it is a warm season crop requiring a relatively long growing season with plenty of sunshine. It is sensitive to frost.
