Forty four testcross progenies obtained from crossing between five CMS and forty one candidate lines were evaluated both in field and laboratory condition to identify candidate restorer line(s). Nineteen testcross progenies were recorded as fully fertile with 100% plant fertility by counting the number of fertile plants from the total number of plants per lines. On the other hand from pollen fertility test, 11 testcross progenies [206A × 001(6), 9905A × 030(2), 9905A × 027(6) (0.57), 206A × 37(1) (0.68), 9904A × 027(4) (0.83), 248A × 020(6) (1.08), 248A × 018 (1.12), 248A × 022 (1.13), 248A × 017 (1.58), 248A × 038(2) (1.96) and 248A × 001(6) (2.02)] were found with 0-2.02% pollen sterility that could be mentioned as fertile or restorer lines for making hybrids. Agronomic performances were also satisfactory for these selected test cross progenies. The genotype 248A × 017 took the shortest time (30.00) for first flowering as well as ripening followed by 248A × 007(1). The highest number of pods per plant was observed in the testcross progeny 248A × 022 (649.59) and the highest number of seeds per pod (30.33) in 248A × 020(6). For seed weight per plant, 206A × 001(6) was recorded with maximum value (0.08g) while the lowest (23.33) number of seeds per plant was found in this progeny. In case of seed yield per plant, 248A × 022 gave the highest yield (30.30). The seed yield of the progenies 248A × 017 (23.49), 9905A × 027(6) (20.39), 248A × 001(6) (17.26), 9904A × 027(4) (17.02) and 248A × 038(2) (16.53) were also in the highest level.

Identification of male fertility restorer genotypes for rapeseed CMS lines towards hybrid development in spring habit rapeseed (Brassica napus L.) adapted for short day winter season was studied. The experiment was conducted at the experimental farm and laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during October, 2008 to March, 2011. An exotic CMS-based F1 hybrid of rapeseed was selfed to get F2 generation with a view to resynthesizing restorer line. As a result a restorer line for Nap248A Z1 and Nap248A Z2 cytoplasmic male sterile lines was identified in the F3 generation of the exotic F1 rapeseed hybrid which appears as the first case so far reported as achievement in Bangladesh in this regard. Genetic analysis further revealed fertility restoration for Nap248A Z1 and Nap248A Z2 cytoplasmic male sterility was controlled by a single dominant nuclear gene as a simple genetic phenomenon.Bangladesh J.

One of the prior directions in spring rapeseed breeding is development of heterotic hybrids. Seed growing of the most hybrids F1 used in production are often carried out by two types of cytoplasmic male sterility, they are polima and ogura. At the Lipetsk Rapeseed Research Institute, fertility restorers on sterile cytoplasm were made and estimated for the main valuable traits. The purpose of the research was to develop effective restorers, which are necessary for obtaining of highly productive hybrids on the Polima type cytoplasmic male sterility (CMS). The object of research was 56 varieties of Brassica napus L., which were selected in 2013. It is noted that hybrids F1 were more productive than the parental forms and the standards (the varieties Ratnik and Rif). The restorer line LHR-1 is of practical interest for the development of hybrids on the Polima CMS.

Отмечена роль Н. И. Вавилова в организации исследований исходного и селекционного материала по биохимическим признакам, определяющим пищевые, кормовые и технологические качества сельскохозяйственной продукции. Выделен перспективный материал для создания сортов рапса с улучшенными пищевыми, кормовыми и технологическими характеристиками; выявлен характер зависимости признаков качества масла от погодных условий (температура, количество осадков и др.). Изучены 50 высокоэруковых (ВЭ) и 40 низкоэруковых (НЭ) линий ярового рапса (Brassica napus L.), выращенных в условиях Ленинградской области в 2012 – 2015 гг. Содержание масла и влажность в семенах определяли методом инфракрасной спектрометрии. Жирнокислотный состав (ЖКС) масла изучали с помощью газожидкостной хроматографии с масс-спектрометрией. Установлено содержание доминирующих жирных кислот для ВЭ и НЭ образцов, а также характер влияния погодных условий на ЖКС масла, в том числе на состав его отдельных фракций. Для ВЭ образцов установлена достоверная отрицательная корреляция (r = –0,96) между содержанием эруковой кислоты и температурой воздуха и достоверная положительная (r = 0,96) с количеством осадков в первую декаду июля. Для НЭ образцов установлена достоверная отрицательная зависимость между содержанием эруковой кислоты и средней температурой воздуха в мае. Выделенные образцы с высоким содержанием олеиновой (61,4 %) и низким линолевой (7,4 %) кислот можно рекомендовать для получения безэруковых сортов рапса, масло которых пригодно для длительного хранения. Контрастные по содержанию эруковой кислоты образцы будут использованы для создания сортов ярового рапса пищевого и кормового назначения, а также для производства биодизеля.
