Callus was successfully induced from the mature endosperm of three Actinidia species: A. arguta, A. deliciosa var. deliciosa (kiwifruit) and A. kolomikta. For the initiation of callus, MS medium supplemented with 2,4-D (2 or 4 mg/l) and kinetin (5 mg/l) was used. Transfer of the callus to medium containing IAA (0.1 mg/l) and BAP (1 mg/l) resulted in the formation of roots in approximately 40% of the endosperm explants of A. deliciosa. The callus, initially yellow-white, turned green when cultured in the light. In A. arguta and A. kolomikta no morphogenic response was observed on this medium. If the cultures were inoculated onto medium with IAA (0.3 mg/l) and 2iP (5 mg/l), in the endosperm calluses of kiwifruit, shoots were formed in addition to roots. In A. arguta a few abnormal shoots were produced in one explant. The sub-culture of A. arguta callus on MS without hormone evoked the production of some roots. No morphogenic response was observed in the endosperm cultures of A. kolomikta on all media tested. The counting of chromosomes in five roots and young leaves of one shoot of A. deliciosa revealed that they were triploids with chromosome number 2n = ~250.

Preliminary observations of plants collected at a natural locality in Jany (Zielona Góra district, Poland) suggested that in some plants dyads occurred mixed with more or less regular tetrads, monads, triads and polyads. Similar results were obtained in plants growing on an unpolluted site at an experimental field in Modlnica near Cracow and in a highly polluted area close to a postfloatation reservoir at the Żelazny Most copper mine near Rudna (Silesia). However, in the plants growing in contaminated soil a higher degree of degeneration processes was observed. Either dyads or tetrads prevailed in the capitula in the analyzed plants. In some of their loculi, dyads and tetrads were mixed with monads, dyads, triads and/or polyads. Microcytes and pollen grains of different sizes were common. The sterility of mature pollen grain was slightly higher in a plant from Żelazny Most (80-85%) than in its derivative from Modlnica (65-75%). Degeneration of whole anthers in the plant from the polluted locality was frequent. In some anthers the destruction of meiocytes started early, together with precocious abortion of the anther tapetum.

Genomic in situ hybridisation (GISH) was used to reveal chromosome pairing in two partly fertile, triploid (2n = 3x = 21) hybrids obtained by crossing the diploid (2n = 2x = 14) Festuca pratensis Huds. (designated FpFp), used as a female parent, with the autotetraploid (2n = 4x = 28) Lolium multiflorum Lam. (designated LmLmLmLm), used as a male parent. The pattern of chromosome pairing calculated on the basis of the mean values of chromosome configurations identified in all 100 PMCs analysed, was: 0.71I Lm + 2.24I Fp + 2.18II Lm/Lm + 0.54II Lm/Fp + 4.18III Lm/Lm/Fp. A relatively high number of Lm/Lm bivalents and Fp univalents, and a low number of Lm/Fp bivalents and Lm univalents indicated that the pairing was preferential between L. multiflorum chromosomes. Other observations regarding chromosome pairing within the Lm/Lm/Fp trivalents also confirmed this preferential pairing in the analysed triploids, as the Fp chromosome was not randomly located in the chain- and frying-pan-shaped trivalents. The similarities and differences in chromosome pairing at metaphase I and the level of preferential pairing between Lolium chromosomes in the different triploid Lolium-Festuca hybrids are discussed.

Breeding scientists have given extensive attention to triploids in trees because of their importance to forestry. Consequently, creating and breeding triploids of good quality has become one of purposes of tree breeding. We chose two autotetraploids (Betula platyphylla, named Q10 and Q65) as female parents and eight hybrid diploids (B. platyphylla × B. pendula, named F1 – F8) as male parents to obtain progenies through controllable pollination, resulting in triploid progenies. Germination rate and germination energy of triploid seeds of Q65 were significantly higher (P < 0.01) than in triploid seed s of Q10. Triploid families with Q65 as female parent had a large quantity of saplings, whereas triploid families with Q10 as female parent had a small quantity of saplings. Triploid families with Q65 as female parent were generally superior in base diameter and height to base diameter ratio when compared to a diploid family. Q65×F3 was preliminarily recognized as the superior family. These results demonstrate that the female parent has a major influence on triploid progenies, although the male parent also has a small influence. The results provided a reference to build seed orchards of triploid birch trees, choose tetraploids as female parents and forecast triploid families of good quality.
