Journal ArticleDOI
Expression of field resistance under Western Australian conditions to Sclerotinia sclerotiorum in Chinese and Australian Brassica napus and Brassica juncea germplasm and its relation with stem diameter
Caixia Li,Hua Li,Krishnapillai Sivasithamparam,Tingdong Fu,Li Yunchang,S.Y. Liu,Martin J. Barbetti +6 more
TL;DR: Stem diameter may be a useful parameter in breeding cultivars of oilseed Brassicas with Sclerotinia resistance and it was evident that both stem lesion length and percentage of plant death were at the lowest level when the stem diameter was approximately 10 mm.
Journal ArticleDOI
QTL analysis on plant height and flowering time in Brassica napus
TL;DR: To identify quantitative trait loci (QTL) controlling plant height (PH) and flowering time (FT), a high stalk/later bloom Brassica napus line '2091' was crossed with a dwarf/early bloom mutant '99CDAM'.
Journal ArticleDOI
The importance of the type and time of inoculation and assessment in the determination of resistance in Brassia napus and B. juncea to Sclerotinia sclerotiorum
Caixia Li,Hua Li,A. B. Siddique,Krishnapillai Sivasithamparam,Phil Salisbury,Surinder S. Banga,Shashi Banga,C. Chattopadhyay,A. Kumar,Ravi P. Singh,Dhiraj Singh,A.K. Agnihotri,S.Y. Liu,Li Yunchang,Jinxing Tu,Tingdong Fu,Y. F. Wang,Martin J. Barbetti +17 more
TL;DR: The results of these studies indicate that the use of appropriate inoculation and assessment methods could significantly reduce variability in the responses commonly observed in screening for resistance in crop plants against Sclerotinia sclerotiorum.
Journal ArticleDOI
Characterizing Variation of Branch Angle and Genome-Wide Association Mapping in Rapeseed (Brassica napus L.).
TL;DR: Findings on multiple novel loci and candidate genes of branch angle will be useful for further understanding and genetic improvement of plant architecture in rapeseed.
Journal ArticleDOI
Comparative genotype reactions to Sclerotinia sclerotiorum within breeding populations of Brassica napus and B. juncea from India and China
Martin J. Barbetti,Shashi Banga,Tingdong Fu,Li Yunchang,Dhiraj Singh,S.Y. Liu,Xintian Ge,Surinder S. Banga +7 more
TL;DR: That populations of similar levels of resistance but narrow variation in the resistance range could be identified is significant, as these are most likely to reliably provide breeders with advanced populations that not only consistently display the level of resistance expected but also reflect genetic diversity of resistance sources needed to successfully develop new more-resistant commercial varieties.
