“…Livingston and Elwinger (1995) found that Wintok and Norline had similar mean winter fi eld survival but often performed diff erently in some environments. Germplasm lines with increased crown freezing tolerance were developed from a cross between Norline and Wintok (Livingston et al, 2004) and some of these were significantly more winter hardy than either Norline or Wintok (Livingston, Uniform Oat Winter Hardiness Nursery, unpublished data, 2004-2006. These results from crosses of Norline and Wintok support the hypo thesis that Wintok has a gene for winter fi eld survival associated with T7C-17 not present in Norline, while Norline has genes not present in Wintok for crown freezing tolerance that are not associated with T7C-17.…”

“…Norline is a winter‐hardy cultivar developed by the Indiana USDA‐ARS oat breeding program and released in 1960 (Patterson and Schafer, 1978). It is winter hardy (Livingston and Elwinger, 1995; Livingston et al, 2004) and contains T7C‐17 (Jellen and Beard, 2000). Norline and Wintok are the long‐term winter‐hardy checks in the Uniform Oat Winter Hardiness Nursery and have similar mean winter hardiness, but often differ for winter field survival in some environments (Livingston and Elwinger, 1995).…”

The reciprocal intergenomic translocation between hexaploid oat (Avena sp.) chromosomes 7C and 17 (T7C‐17) has been associated with the division of cultivated oat into A. sativa L. and A. byzantina K. Koch species and differences in crown freezing tolerance and winter field survival. The objectives of this experiment were: (i) to validate the association of T7C‐17 with crown freezing tolerance and winter field survival in a population derived from a cross of the non‐winter‐hardy ‘Fulghum’ (non‐T7C‐17) with winter‐hardy ‘Norline’ (T7C‐17); (ii) to determine if preferential selection for T7C‐17 occurred during inbreeding; and (iii) to examine the association of T7C‐17 with the winter hardiness component traits heading date, plant height, and vernalization and photoperiod responses. Crown freezing tolerance and vernalization and photoperiod responses were evaluated in controlled environment studies. Heading date, plant height, and winter field survival were evaluated in field experiments during two seasons. The presence of the translocation was associated with greater crown freezing tolerance, winter field survival, and days to flowering. Translocation status was not associated with vernalization and photoperiod responses or plant height. The T7C‐17/non‐T7C‐17 segregation ratio was 2:1. These results confirmed the importance of T7C‐17 in conferring winter hardiness traits in winter oat and preferential selection for the translocation during inbreeding.

“…A stagnation was recorded in oat winter hardiness in the second half of the last century until a progress was reported in North Caroli na, USA, first as a result of crossing the winterhardy cultivars ' Wintok' and 'Norline' (Liv ingston, Elwinger, 1995;Livingston et al, 2004), and later after application of the wild species Avena macrostachya Bal. ex Coss et Dur.…”

Освещена 100-летняя история изучения и использования генетических ресурсов засухо-и солеустойчивых кормовых культур, и их диких родичей в республиках Средней Азии и южных регионах России. Дана оценка жизнеспособности образцов ежевики в условиях предгорной зоны Северного Кавказа после их хранения в культуре in vitro. Рассмотрены итоги работы по разработке технологии селекции низкопентозановой озимой ржи и созданию сортов, пригодных для использования в комбикормовой промышленности. Обобщены результаты изучения коллекции нута в Омской области. Приведены достижения селекции по улучшению зимостойкости овса в Польше, выделены эффективные источники зимостойкости для получения новых гексаплоидных линий. Представлена история селекции овса на Кубани. Продемонстрированы возможности использования морфолого-биологических признаков при экспертизе сортов на отличимость, однородность и стабильность на примере сортов гибридной алычи селекции Никитского ботанического сада. Обсуждается генетический контроль восстановления фертильности пыльцы у линий льна с цитоплазматической мужской стерильностью. Рассмотрены результаты применения молекулярных маркеров генов устойчивости к картофельной цистообразующей нематоде на разных этапах селекции картофеля. Представлен биографический очерк выдающегося цитогенетика Г. А. Левитского. Табл. 33, рис. 14, библиогр. 173 назв. Для ресурсоведов, ботаников, генетиков, селекционеров, преподавателей вузов биологического и сельскохозяйственного профиля.
