“…It seems that -also in the light of results of the progenies of the clones, which will be discussed later -only two of the many causes of the so-called pseudo-self-compatibility (PANDEY, 1959 ;DENWARD, 1963 ;LINSKENS and KROH, 1967) remain as a possible explanation, viz : 1 . an effect of extraneous environmental factors on the action of certain S-alleles, or their products, directly or via interaction with their genetic background ; 2 .…”

Attempts were made to break the self-incompatibility in L. peruvianum by selection of mutated S-alleles through large-scale self-pollination on clones with pollen which was mutagenically treated in different stages of development . Besides self-compatibility was searched for in inbred lines .The self-incompatibility in L. peruvianum was found to be very strict indeed . From more than 22,000 self-pollinations on 5 clones 1527 seeds were obtained, seed set being very erratic . The possible causes of this seed set are discussed . From 1527 seeds 1036 plants were raised and tested for self-compatibility .In the progenies of 4 clones from 823 plants tested, 7 were more or less self-compatible . It is concluded that this self-compatibility was spontaneous and not the result of the mutagenic treatment .In the progeny of the fifth clone plants were found which reacted as self-compatible at a temperature of about 40°C and as self-incompatible at lower temperatures . It is suggested that this character -a high temperature sensitive incompatibility reactionis governed by one recessive gene .In inbred lines plants were found with a stable form of self-compatibility and also plants with a high temperature sensitive incompatibility reaction.The problems of an incompatibility research on inbred material are discussed . A brief survey is given of some of the characters found in inbred L . peruvianum .

“…As observed by LINSKENS & KROH (1967) for wide crosses in cereals, few pollen grains germinated on the stigma and penetrated the style in our interspecific Medicago crosses. We also noted abnormal pollen tube -style reactions such as retardation of tube growth, branching of pollen tubes as observed in spinach (RAMANNA & MUT-SAERTS, 1971) and avocado (SEDGLEY, 1979), heavy deposition of callose tissue along and at the end of tubes as for apples (STOTT, 1972), pollen tubes coiled rather than entering the embryo sac cavity similar to those in tulips (KHO & BAER, 1971) and tubes that twisted sharply and grew back in the direction of the style as in avocado (TOMER & GOTTREICH, 1975).…”

INDEXWORDS Medicago saliva. alfalfa. M. scutellata, M. disciformis, M. rigidala, UV fluorescence microscopy. SUMMARY Pollen germination and pollen tube growth after self-and intra-and interspecific pollinations of annual [M. scufellata (L.) MILL., M. disciformis DC., and M. rigidula (L.) ALL.] and perennial (M. sativa L.) Medicago species were studied using a Carl Zeiss microscope with a fluorescence filter attachment.Self-pollination of self-fertile annual and intraspecific pollination of cross-fertile perennials were characterized by high pollen germination and rapid normal pollen tube growth. In contrast pollen germination percentages were very low and many pollen tube growth abnormalities occurred following interspecific pollination and self-pollination of self-sterile plants. The time period from pollination to fertilization for interspecific crosses was about double that following self-pollination of the annual species. However, fertilization occurred frequently following interspecific pollinations. Much of the sterility was due to factor(s) operating after fertilization.

“…For this purpose the SI barrier has to be broken . This can be done by mutilation or removal of the stigmata (see the review by LINSKENS and KROH, 1967), changing the nutritional conditions (STOUT, 1931), pollen transplantation (KROH, 1966), chemical treatments (TATEBE, 1968), treatment with CO 2 (NAKANISHII et al ., 1969), high temperature (GONAI and HINATA, 1971) and bud pollination . The latter method is widely used for hybrid seed production, but is very time-consuming and demands skilled labour for maximal yield (JOHNSON et al ., 1970) .…”

In Brussels sprouts and Savoy cabbage the sporophytic incompatibility barrier can be broken by applying a direct electric potential difference of 100 V between pollen and stigma during pollination . The effect, measured as the number of seeds per flower, depends on the kind of plant and the degree of incompatibility . The mechanism underlying this phenomenon as well as the possible practical use of `electric aided pollination' (EAP) are discussed .
