Pollination is chiefly done by bees. Male-sterile lines: Breeder seed production of A-lines is carried out by growing the A-line and its corresponding B-line together in an isolated plot. Isolation requirements (Table 1) The crop must conform to the following standards as regards distances from neighbouring sources of pollen: Crop Minimum distance 1 2 (1) For the production of basic seed – - from any pollen source of the genus Beta 1,000 metres The isolation distance required for A-line × B-line production fields is >300 m.

Isolation distance and Modification of isolation distance. ISOLATION DISTANCES The subject of isolation distances in tomatoes has either been ignored in most seed production As rapeseed-mustard is prone to shattering, B-line plants should be harvested just after the completion of pod setting on A-line to avoid seed admixture of A-line and B-line. Land selection The land selected should not be cultivated with groundnut in the previous season. Maintenance of genetic purity for certified seed production of conventional or male sterility based hybrids depends upon the use of safe isolation distance.

If you’re harvesting seed for a seed bank or for commercial purposes, you’ll want it to be absolutely true-to-type and the isolation distance will be greater than for the home gardener who simply wants to harvest his own vegetables and who will probably be more intrigued than disappointed by the occasional presence of a vegetable that isn’t true-to-type. Table 1 specifies the recommended isolation distances for vegetable crop seed production. 3. For example, for certified seed production, very high purity is required (virtually 100%). Nursery for breeder seed production of hybrid parents and varieties are described below. Isolation distance is the distance by which the seed crop is separated from any other variety of the same crop. Isolation distance: Isolation distance is the minimum separation required between two or more varieties of the same species for the purpose of keeping seed pure. Cauliflower is mainly a cross pollinated crop. In some cases, e.g., hybrid maize the minimum isolation distance may be considerably reduced by planting border rows of the pollinator parent and by choosing a larger field for seed production. Consider the following things while selecting plot for the seed production. Tomato seed germinates in the range of 50 to 95oF (10 oC to 35 C).
