A NEW TECHNIQUE FOR TOMATO HYBRID SEED PRODUCTION: DIRECT HAND-POLLINATION OF MALE-FERTILE BS LINES.
The authors propose a new technique of producing F1 seeds based on hand pollination of intact flowers from a male-fertile seed-parent line genetically marked by the bs-trait.
The comparison between this technique and that involving both emasculation and pollination by hand was carried out in 1978 and 1979 using a male-fertile line homozygous for bs and c traits. The new procedure offers the following advantages: better fruit set; higher number of seeds per fruit; negligible degree of F1 seedling 'contamination' (% of selfing); a price-cost (estimated for 100 g of hybrid seeds) about 60% lower; and last, but not least, the practical use of any bs line endowed with good combining ability, without resorting to male sterility genes.
