“…In the current study, the S -genotype of all maternal parents including ‘Baigent’ (S 2 S 5 ), ‘Cripps Pink’ (S 2 S2 3 ), ‘DT2’ (S 1 S 9 ), ‘Olsentwo Gala’ (S 2 S 5 ), ‘LJ-1000’ (S 2 S2 4 ), and ‘WA 38’ (S 5 S 24 ) are known [ 41 , 42 ]. However, the S -genotype of several of the utilized crabapples is unknown, except for ‘Dolgo’ (S 32 S 33 ) [ 42 ] and ‘Manchurian’ (S 5 S 39b ) [ 43 ]. Considering that most of the paternal parents performed significantly better than the self-pollination control after 48 h, the exception observed in ‘Baigent’ styles suggested that all maternal and paternal combinations are at least partially compatible.…”

Flower receptivity is a limiting factor for the fertilization of several tree fruit. The effective pollination period (EPP) can be used to determine flower longevity and identify limiting factors by assessing stigmatic receptivity, pollen tube growth rate, and ovule longevity. EPPs were determined for three apple cultivars under natural field conditions in Washington State in 2019 and 2020. In addition, a greenhouse study, performed under semi-controlled conditions, evaluated the influence of six maternal parents on the pollen tube growth performance of six pollen sources. The duration of the stigmatic receptivity ranged from 6.3 to 8.1 days, depending on the cultivar and year—pollen tubes required between 5.5 and 7.0 days from the stigma to reach the ovules. Ovule longevity of non-pollinated flowers varied between 8.2 and 11.3 days. Combinations of these factors resulted in EPPs ranging from 3.0 days for ‘Rubinstar’ to 5.6 days for ‘Olsentwo Gala’ in the present experimental conditions. The greenhouse study revealed that parentage affected pollen tube growth performance. Importantly, a significant interaction between maternal and paternal factors indicated that the performance of different pollen sources depended on the maternal parent and that general recommendations on pollination need to account for the maternal parent.

Self-(In)compatibility Systems: Target Traits for Crop-Production, Plant Breeding, and Biotechnology

et al. 2020

Self-incompatibility (SI) mechanisms prevent self-fertilization in flowering plants based on specific discrimination between self-and non-self pollen. Since this trait promotes outcrossing and avoids inbreeding it is a widespread mechanism of controlling sexual plant reproduction. Growers and breeders have effectively exploited SI as a tool for manipulating domesticated crops for thousands of years. However, only within the past thirty years have studies begun to elucidate the underlying molecular features of SI. The specific S-determinants and some modifier factors controlling SI have been identified in the sporophytic system exhibited by Brassica species and in the two very distinct gametophytic systems present in Papaveraceae on one side and in Solanaceae, Rosaceae, and Plantaginaceae on the other. Molecular level studies have enabled SI to SC transitions (and vice versa) to be intentionally manipulated using marker assisted breeding and targeted approaches based on transgene integration, silencing, and more recently CRISPR knock-out of SI-related factors. These scientific advances have, in turn, provided a solid basis to implement new crop production and plant breeding practices. Applications of self-(in)compatibility include widely differing objectives such as crop yield and quality improvement, marker-assisted breeding through SI genotyping, and development of hybrids for overcoming intra-and interspecific reproductive barriers. Here, we review scientific progress as well as patented applications of SI, and also highlight future prospects including further elucidation of SI systems, deepening our understanding of SI-environment relationships, and new perspectives on plant self/non-self recognition.

“…Повна генетична сумісність настає, коли сорти відрізняються обома своїми S-локусами, напівсумісність, коли вони відрізняються в одному зі своїх двох S-локусів, і повна несумісність, коли обидва сорти мають однаковий S-генотип (Mir et al, 2016). Для полегшення роботи з перехреснозапильними рослинами на ранніх етапах використовують молекулярний аналіз для виявлення S-алелей в існуючих сортів, зрідка з можливим виявленням нових або рідкісних S-алелей (Cho et al, 2014, Mir et al, 2016, Sheick et al, 2018.…”
