Parthenogenetic development of seeds after pollination with irradiated pollen was studied in the dioecious species Actinidia deliciosa (kiwifruit). In total, 479 pollinations were made involving three recipient female cultivars, with five male and two hermaphrodite pollen donors. Pollen was irradiated with doses of 0.5, 0.7 and 0.9 kGy, all three doses produced parthenogenetic seeds. The 0.7 kGy dose yielded the highest number of germinating seeds (708 of a total of 723), of which 609 developed into seedlings, and 334 survived to grow into plants. Ploidy level was evaluated by cytological studies and stomatal guard cell size. In a total of 416 seedlings and plants evaluated, 332 plants were hexaploid ('diploid' 2n = 170) and 84 plants were triploids ('haploids' 2n = 85).

“…From the improved diploid clones tetraploid cultivars are produced through sexual polyploidization . In this context, efficient methods have been developed for the production of potato dihaploids (Hougas et al ., 1964 ;Hermsen & Verdenius, 1973), and diploid potato clones that produce 2n-gametes have been selected in the past (Mendiburu & Peloquin, 1977 ;Jacobsen, 1980). Among many of the 2n-gamete forming diploid potato clones, the following five genotypes have been widely used in breeding programmes as well as in cytogenetic investigations : US-W 5293 .3, US-W 5295 .7, US-W 5337 .3, US-W 7589 .2 and 772102-37 .…”

Selection of diploid potato genotypes that produce high frequencies of 2n-pollen grains in different environments is an important requirement for analytic breeding as well as for true potato seed production. In this context, quantitative estimates of 2n-pollen formation were made in two type of diploid potato populations . One population set consisted of the progeny from diallel crosses of five well-known diploid potato clones (A = US-W 5293 .3, B = US-W 5295 .7, C = US-W 5337 .3, D = US-W 7589 .2 and E = 772102-37) . Another population set was obtained by pollinating three genotypes of Solanum phureja, IvP35, IvP48 and IvP101 with clones A, C and E . It was observed that the behaviour of the parental clones with respect to 2n-pollen grains formation in different environments, such as in Europe and China, was stable . The correlation coefficient between means of 2n-pollen grains frequency of combinations and percentage of genotypes with more than 5% 2n-pollen grains in a given combination were estimated and that between mean and maximum frequency of 2n-pollen grains formation in each combination . The results showed that the former coefficients were significant whereas the latter were not . The combining ability analysis revealed variation in 2n-pollen grains formation between families . Specific combining ability (SCA) effects contributed much more than general combining ability (GCA) to the variation in 2n-pollen grains formation . The broad-sense heritability of 2n-pollen grains formation was estimated to vary between 0 .45 and 0 .53 and the narrow-sense heritability was calculated to be 0 .15 and 0 .20 in the two types of populations . This means that additive variance was relatively low . Two to four genes were estimated to control the inheritance of 2n-pollen grains formation .

“…Les clones obtenus sont appelés dihaploïdes puisqu'ils correspondent à la phase haploïde de l'espèce cultivée mais au niveau diploïde du groupe d'espèces. Cette obtention de dihaploïdes peut être intégrée dans un programme de sélection (Hougas et al, 1964;Hermsen et Verdenius, 1973 (Karp et al, 1984;Sonnino et al, 1988;Rousselle et al, 1990); -fusion de protoplastes (Wenzel et al, 1979); -polyploïdisation sexuelle grâce aux diplogamètes (Mendiburu et Peloquin, 1977 (Hawkes, 1990 (Frandsen, 1968) (Cornuet, 1987).

L). A large number (3 027) of dihaploids (2 n = 2 x = 24) has been obtained from 445 tetraploid (2 n = 4 x = 48) potato clones by means of in situ parthenogenesis. These pollinations gave about 2 to 3 seeds per fruit. Of the seedlings 27% were dihaploid. The dihaploids had weak vigour and were all male sterile, but showed a wide variability for plant aspect, tuber characteristics, processing quality (dry matter content and ability to be fried) and disease and pest resistance. They were subsequently included in hybridizations with 4 diploid related species (S phureja, S stenotonum, S chacoense and S vernei). First generation hybrids were intercrossed or crossed with other dihaploids and different combinations were then obtained. Hybrid groups were distinguished depending on the species used. These hybrids were very vigourous and exhibited enough male fertility, the latter depending on the dihaploid used. They were described for characters such as dry matter content and chipping quality. The advanced diploid populations prove to be adapted to French cropping conditions and show interesting variability. They constitute a basis for the resynthesis of tetraploid clones and they will be used for the application of biotechnology and the introduction of new related species.Solanum tuberosum = potato / breeding / diploid / related species INTRODUCTION
