Effect of ethrel on lentil (Lence culinaris L.) to induce male sterility
Present study examined the effect of ethrel on lentil (Lence culinaris) to induce male sterility. The term sterility generally includes all those cases that involve failure of production of viable off springs, fruits or seeds. Sterility or barreners becomes most apparent on intra or interspecific hybridization and is essentially a mechanism connected with sexual reproduction in plants. Chemical induction of male sterility has been developed primarily for the production of hybrid crops. The highly competitive hybrid seed market has narrowed the field to a few active agents currently under commercial development. Because prior knowledge of their biochemical action was not required for commercialization, their mechanism are largely unknown. Chemical hybridizing agent (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 induce male sterility has been developed by ethrel in lentil. (Lens culinaris L.) ethrel known to induce male sterility in some crops and induce pollen sterility in lentil. Foliar application of ethrel brought about complete pollen sterility. This pollen sterility was long lasting. The effect of ethrel treated plants caused almost complete sterility ranging between 97-98.33%.
