“…The leaves of haploids of fruit crops tend to be smaller than those of diploid plants [2,36,37]. Haploids of trifoliate orange, mandarin, tangor and tangelo also show rosette morphology with small leaves in Citrus and related genera [17,21,25].…”

“…Details of the morphology of DH plants have rarely been reported for fruit crops, although DH plants of several species have been produced, e.g., kiwifruit, apple, banana, sweet cherry, peach, and Japanese pear [1,2]. Several DH plants of apple were produced by in vitro androgenesis and in situ parthenogenesis, and their morphology and reproductive potential have been reported [39][40][41].…”

“…Haploid and doubled haploid (DH) plants are of great value for genetic analyses and developmental studies, as well as for premeditated plant breeding [1][2][3][4][5]. Technologies using DH plants also enhance the effectiveness of the selection of desired recombinants, especially when quantitative traits are evaluated [6].…”

Haploid and doubled haploid (DH) plants are of great value for genetic analyses and premeditated breeding. This is especially true for woody species, which are generally characterized by a long reproductive cycle, a high degree of heterozygosity, a large plant size, and self-incompatibility. In Citrus and related genera, some haploid and DH plants have been produced by techniques such as anther culture, interploid hybridization, and the pollination of irradiated pollen. However, there are few reports of the characteristics of haploid and DH plants' flowers, fruits, or reproductive potential. We selected a haploid progeny among small seed-derived seedlings obtained from 'Banpeiyu' pummelo [C. maxima (Burm.) Merr.], and we produced the DH plant of this haploid using colchicine-treated axillary shoot buds. Both this haploid pummelo and the DH pummelo showed normal growth and produced many flowers and fruit. In this chapter, we describe about the morphological characteristics and the reproductive potential of the haploid pummelo and the DH pummelo.

“…The other two methods deliver near-homozygous lines, which for cultivar purposes are usually acceptable, but provide additional benefits. These methods are regularly reviewed, and new modifications are often published (Choo et al, 1985;Snape, 1989;Maluszynski et al, 2003;Forster et al, 2007;Touraev et al, 2009;Tadesse et al, 2012;Dwivedi et al, 2015;Humphreys and Knox, 2015).…”

P lant breeding, certainly in the era before genomics and marker-assisted selection, was often referred to as a "numbers game." The more crosses, the more likely it is to find improved genetic combinations. We propose a newly integrated breeding strategy for self-fertilizing crops that dramatically reduces the number of crosses being promoted while increasing the likelihood of obtaining superior new cultivars. This strategy emerges from experiments in the Bread Wheat Program of the International Center for the Improvement of Maize and Wheat (CIMMYT).In the late 1990s we noticed that ~8% of the elite new lines in the International Bread Wheat Screening Nursery (IBWSN) for international distribution were derived from <20 crosses. The remaining 92% of elite lines came from 5000 to 10,000 crosses. These few original crosses, and the lines derived from them, represented a strategy that we now describe as hybrid-enabled line profiling (HELP). This strategy offers breeding programs for selfing crops enormous benefits through improved performance. It Cross the Best with the Best, and Select the Best: HELP in Breeding Selfing CropsMaarten van Ginkel* and Rodomiro Ortiz ABSTRACT Hybrid-enabled line profiling (HELP) is a new integrated breeding strategy for self-fertilizing crops that combines existing and recently identified elements, resulting in a strategy that synergistically exceeds existing breeding concepts. Heterosis in selfing crops is often driven by additive and additive ´ additive gene action, the molecular basis of which is increasingly being revealed. Unlike nonadditive heterosis, additive forms can be relatively easily fixed in homozygous lines, meaning that their seed can simply be resown to express the same "heterosis." Crossing diverse, complementary "selfing" parents to create the desired trait or allele line profile requires strict male sterility of the female; this can now be achieved relatively easily through present and emerging chemical, environmental, or genetic techniques. Fairly small amounts of hybrid seed are needed, with no need to scale up seed production, as it is not the hybrid that will be commercialized. After multilocation testing, homozygous lines from only the most superior hybrids, driven mainly by additive effects and additive ´ additive gene action, are rapidly derived using techniques such as doubled haploids. Multilocation testing and molecular confirmation of target line profiles then identify superior lines for release to farmers. The HELP strategy integrates modern high-throughput versions of existing and new concepts and methodologies into a breeding system strategy that focuses on the most superior crosses, <10% of all crosses. This focus results in significant increases in efficiency and can reverse the edible yield plateauing seen or feared in some of our major selfing food crops.M. van Ginkel,

“…На сегодняшний день в мировой практике с применением гаплоидной биотехнологии создано почти 300 сортов сельскохозяйственных культур. Список видов, у которых получены гаплоиды и удвоенные гаплоиды, постоянно пополняется, появляются новые обзорные публикации, посвященные гаплоидии, проводятся генетические и фундаментальные исследования на DH-линиях, создаются новые сорта и гибриды на основе линий удвоенных гаплоидов, в том числе овощных культур (61)(62)(63)(64)(65). Методы гаплоидии во ВНИИССОК на растениях моркови и капусты белокочанной начали развиваться в 1990-е годы.…”

В статье представлены материалы по истории образования первого овощеводческого научного учреждения в России-Грибовской овощной селекционной опытной станции, на базе которой был создан Всероссийский НИИ селекции и семеноводства овощных культур, впоследствии реорганизованный в Федеральный научный центр овощеводства (ФГБНУ ФНЦО). Деятельность центра берет начало с 1920 года, когда под руководством профессора С.И. Жегалова на Грибовской опытной станции была заложена теоретическая и практическая база для развития отечественной селекции. В последующие годы значительное внимание ученых было уделено разработке и совершенствованию методов селекции, повышающих эффективность отбора, а также ускорению селекционного процесса по созданию адресных сортов и гибридов. Применительно к основным овощным культурам разработаны методы межвидовой гибридизации (Н.И. Тимин с соавт., 2013; А.Ф. Агафонов с соавт., 2018), молекулярного маркирования (Т.П. Супрунова с соавт., 2011; Е.А. Домблидес с соавт, 2015), клонального микроразмножения и получения удвоенных гаплоидов, успешно использованные в селекции (М.С. Бунин с соавт., 2004). Предложены базовые протоколы культуры микроспор in vitro для большинства капустных культур (Е.А. Домблидес с соавт., 2016), культуры неопыленных семяпочек-для тыквенных культур (Н.А. Шмыкова с соавт., 2015). Разработана технология получения удвоенных гаплоидов моркови столовой в культурах пыльников, неопыленных семяпочек и микроспор in vitro (Т.С. Вюртц с соавт., 2016). Доказана экономическая выгода использования современных биотехнологических методов in vitro при создании гибридов: сроки создания гибридов сокращаются с 12 до 6 лет, финансовые затраты снижаются в 2 раза (A. Mineikina с соавт., 2019; T. Vurtz с соавт., 2019). Показано ухудшение фитопатологической обстановки и расширение ареалов новых вредоносных возбудителей на овощных культурах. На основе иммунологической, молекулярногенетической, морфофизиологической оценки селекционного материала овощных культур в условиях искусственного заражения, провокационного и естественного инфекционных фонов выделены источники резистентности к экономически значимым болезням: капусты-к киле, свеклы столовой-к церкоспорозу, фасоли овощной-к вирусным болезням, лука-к пероноспорозу (И.А. Енгалычева с соавт., 2019). При создании сортов с высоким содержанием биологически активных веществ и антиоксидантов широко применяются физиологические и биохимические методы. С использованием созданных сортов овощебахчевых культур разработаны технологии получения функциональных продуктов питания, включая новые виды чая лечебно-профилактического действия, безалкогольные напитки, пищевые красители, и кондитерские изделия (М.С. Гинс с соавт., 2017). Предложены рецептуры безглютеновых хлебобулочных изделий с применением интродуцированных культур якона, амаранта и дайкона. Разработаны технологии обогащения селеном овощных культур для употребления в свежем виде и в качестве сырья для функциональных продуктов (Н.А. Голубкина с соавт., 2018). ФНЦО осуществляет координацию научных исследований по се...
