The objective of this experiment was to evaluated the male sterilizing activity induced by the chemical hybridizing agent (CHA) on lentil (Lens culinaris
Male sterility is defined as an absence or non –functional of pollen grain in plant in capability of plants to produce or release functional pollen grain. The use of male sterility in hybrid seed production has great importance as it eliminate the process of mechanical Emasculation. Chemical hybridizing agents (CHAs) can be used on a large scale for commercial production of hybrid seed. Most CHAS are applied to plants only at a critical stage of male gametophyte development. The aim of this study was to investigate an induction male sterility has been developed by surf excel in lentil. Lens culinaris L. surf excel a detergent known to induce male sterility in some crops and pollen sterility in lentil. Foliar application of surf excel brought about complete pollen sterility. This pollen sterility was long lasting. The effect of surf excel treated plants caused almost complete sterility ranging between 91.33-99.00%.
