“…InterspeciJicpollen tube growth inhibition andself-incompatibility In the L. peruvianum material studied the self-compatibility is based on mutated S-alleles or on genes modifying the S-allele action (HOGENBOOM, 1972b). In some of the lines used, obtained by selfing of self-compatible plants, one intact S-allele may Euphytica 21 (1972) 411 be present and active; besides mutated S-alleles will be present.…”

The validity of the current hypotheses on the inheritance of unilateral incompatibility is disputed and the importance of intrapopulational research on the inheritance of unilateral incompatibility is emphasized.Such research has been carried out on the unilateral incompatibility between L. peruvianum and L. esculentum with inbred material of L. peruvianum. The results indicate that in this species the inhibition of L. esculentum pollen tube growth, built up of distinct processes, is based on independent dominant genes, and that the breakdown of the phenomenon is a consequence of segregation of recessive alleles, the expressivity of at least some of these being influenced by environmental factors.Research demonstrating differences between self-incompatibility and interspecific pollen tube growth inhibition is reviewed and it is concluded from this and own research that the two phenomena are distinct.

“…The sudden and unreproducible seed productions after selfing in their material closely agree with our results, although the numbers of seeds per pollinated flower in our material were generally smaller . Later more indications were found that indeed generation of new S-alleles occurs in this material (HOGENBOOM, 1972) . After mutagenic treatment of seed of an S 1 S3 -population of L .…”

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 .

“…The SI system in L. peruvianum has been classified as a gametophytic rather than sporophytic type since its pollen phenotype is determined by the genotype of the individual microspore rather than that of the pollen-producing plant (Lamm 1950). The genetic control of SI in L. peruvianum appears to be monofactorial (Lamm /950;McGuire and Rick 1954;Martin 1961 ;Hogenboom 1972c;Tanksley and Loaiza-Figueroa 1985), though the capability to fully manipulate this trait remains elusive.…”

Stylar self-incompatibility barriers in L. peruvianum can be avoided if pollen germination and growth through immature pistils is promoted under specific environmental conditions approximately 2-3 days before the initiation of anthesis. Since immature stigmas lack sufficient exudate for pollen germination, the sandwiching of a thin layer of pollen germination medium between the stigma and a mineral oil layer containing pollen allows precocious pollen germination and some compatible pollen tube growth through the style. This procedure is rapid, inexpensive, applicable in the field, and makes efficient use of pollen. Consistent though low seed yields have been obtained. A high proportion of aborted seed, seedling lethals, and aberrant seedling phenotypes in selfed progeny indicate the presence of strong post-zygotic barriers to such selfing. No evidence for a reduction in the strength of the SI response with increasing pistil age was observed.
