Effect of a low seed lignin content on seed yield and quality in winter oilseed rape ( <scp> <i>Brassica napus</i> </scp> )

چکیده
Increasing demand for vegetable oil and protein requires breeding efforts to enhance the yield of oilseed rape. This can be achieved by reducing seed cellulose, hemicellulose lignin content. The objective study was analyse important agronomic traits two distinct bulks genotypes from crosses, with low (6%) high content (10%). genotype were formed mixing seeds 12 doubled haploid lines either or selected large populations based on content, flowering time plant height. field-tested in replicated trials. Seed quality analysis confirmed significant differences between bulks. moderately higher both crosses. Seed, crosses significantly Further reduced fibre will help increase

Effect of Sowing Method and N Application on Seed Yield and N Use Efficiency of Winter Oilseed Rape
In northern Europe, replacing winter barley with winter wheat as the preceding crop for winter oilseed rape (Brassica napus L.; WOSR) often results in a delayed WOSR sowing and poor autumn growth. Based on data from a field experiment running in 2009/2010, 2010/2011, and 2012/2013, this study aims (i) to investigate how a delayed sowing method affects seed yield, N offtake with the seeds, and a...

Breeding and production of drought tolerant cultivars for arid and semi-arid area is very important. The present experiment was carried out to evaluate the effects of drought stress on seed yield and yield components of oilseed rape as well as identification of high yielding and drought stress tolerant genotypes. Eighteen new winter oilseed rape lines and commercial cultivars were evaluated und...
متن کاملLeaf Senescence, Root Morphology, and Seed Yield of Winter Oilseed Rape (Brassica napus L.) at Varying Plant Densities
In this study, the yield and yield components were studied using a conventional variety Zhongshuang 11 (ZS 11) and a hybrid variety Zhongyouza 12 (ZYZ 12) at varying plant densities. The increase in plant density led to an initial increase in seed yield and pod numbers per unit area, followed by a decrease. The optimal plant density was 58.5 × 104 plants ha-1 in both ZS 11 and ZYZ 12. The furth...
متن کاملThe impact of sulfate restriction on seed yield and quality of winter oilseed rape depends on the ability to remobilize sulfate from vegetative tissues to reproductive organs
Our current knowledge about sulfur (S) management by winter oilseed rape to satisfy the S demand of developing seeds is still scarce, particularly in relation to S restriction. Our goals were to determine the physiological processes related to S use efficiency that led to maintain the seed yield and quality when S limitation occurred at the bolting or early flowering stages. To address these qu...
