Abstract:
Tomato (Lycopersicon esculentum Mill. 2n=2x=24) belonging to family solanaceae is highly self-pollinated with perfect flower, therefore, use of male sterile lines is essential for developing commercial tomato hybrid. The acquisition of male sterile line with good combining ability, sufficient style length to expose the stigmatic surface for cross pollination and simple maintenance with low cost of production lilts been a paramount interest of tomato breeders. Male sterility either genetic or non-genetic mikes the pollen unavailable or such tomato Mowers are incapable of selling seed through selling. Thus, a male sterile line can he used as female parent and can produce a bulk quantity of seed due to crass-pollination. The seed set on the male .sterile plant is hybrid, which is used for growing commercial hybrid. On an average, under Meld conditions, a normal tomato variety yields 16-25 tones/ha while hybrids often produce 60-80 tones/ ha. However, to exploit the benefits, farmers have to buy fresh seed in every cropping season. In this review article a brief survey on nature of tomato male sterility and its possible utilization in the development of cost effective hybrid development program has been discussed from breeding point of view.
