Abstract

Seeds from maternal line (G-3) of hybrid cucumber cultivar Pobeda F were irradiated with a helium-neon laser at 632.8 nm and an output power of 20 mwt, and then with gamma rays from radioactive cobalt (Co-60). The following variants were tested: sevenfold laser irradiation; gamma irradiation with 10 Gy dose; irradiation with combined laser + gamma rays.
These treatments were investigated in a field experiment under conditions suitable for hybrid seed production.
Seeds from the parent line were not irradiated.

It was established that as a result of irradiation, the yield of reproductional seeds increased by 15.6 – 28%, germination energy by 2.3 – 3.4 %, field germinability by 8.2 – 8.5 % and the weight of 1000 air dry seeds by 1.5 – 5.8 %. The increase in seed yield was connected mainly with the higher yield of ripe fruits (14.6 – 21.6 %) and to a lesser extent (11.1 – 15.5 %) with the larger seed quantity formed into one fruit.
The higher radiobiological effect was obtained by irradiation with a combination of laser + gamma rays.
