Two years study was carried out during 2006-07 and 2007-08 crop seasons to study the response of different genotypes of oilseeds Brassica to Lipaphis erysimi (Kaltenbach) infestation both under field and screen house conditions and to find out the relationship of various biochemical constituents to aphid infestation. Among the various genotypes, the population of L. erysimi was significantly high on Brassica rapa variety brown sarson cv. BSH 1 and B. rapa var. yellow sarson cv. YST 151 in…

Biochemical changes in the Brassica juncea-fruticulosa introgression lines after Lipaphis erysimi (Kaltenbach) infestation
TLDR
A general trend of decline in flavonols, total sugars and free amino acids content was observed after aphid infestation in all the genotypes, and there was downregulation of glucosinolates and upregulation of total phenols as against opposite trend observed in BSH-1 and PBR-210.
Host–pathogen interactions of Brassica genotypes for white rust (Albugo candida) disease severity under aided epiphytotic conditions in India
TLDR
It can be concluded from the study that some of the genotypes showed resistant reaction to prevalent isolates of an area and it is advised to test the genotype for the reaction to a particular/range of diseases for the specificity in performance, if any, before release for general cultivation in a particular area.
Field efficacy of insecticides against two different feeding guilds: the sap sucking Lipaphis erysimi (Kaltenbach) and foliage feeder Pieris brassicae (L.) infesting Indian mustard
TLDR
Four insecticides against both the large white butterfly and turnip aphid in Punjab, India are evaluated for their field efficacy at two locations and spray of chlorpyriphos 20 EC @ 1.5 litre ha-1 could be the best option for control of both the pests.
Using wild relatives and related species to build climate resilience in Brassica crops
TLDR
This review provides a working guide to the use of wild relatives and related crop germplasm to improve biotic and abiotic resistances in Brassica crop species.
Perspectives for integrated insect pest protection in oilseed rape breeding.
TLDR
Researchers and oil Seed rape breeders can nowadays benefit from an array of new technologies which in combination will accelerate the development of improved oilseed rape cultivars with multiple insect pest resistances/tolerances in the near future.
Screening of tree leaves for bioactive components and their impact on in vitro fermentability and methane production from total mixed ration
TLDR
It was concluded that TMR supplemented with leaves of M. indica, A. nilotica, P. guajava, C. fistula, E. globules and P. dactylifera at 1% has great potential to improve digestibility and or decrease methane production.

Screening of wild crucifers for resistance to mustard aphid, Lipaphis erysimi (Kaltenbach) and attempt at introgression of resistance gene(s) from Brassica fruticulosa to Brassica juncea
TLDR
The biochemical analysis suggested the possibility of high concentration of lectins to be associated with low aphid infestation in B. fruticulosa and AD-4 after 30 days of aphid release while 80% mortality was observed on BSH-1.
Aphid resistance in Brassica crops: challenges, biotechnological progress and emerging possibilities.
Role of Nonpreference in the Resistance of Cabbage Varieties to the Onion Thrips (Thysanoptera: Thripidae)
TLDR
For the frame (outer) leaves of the cabbage plant, ‘Falcon’ was generally preferred over the other varieties, although the numbers of thrips colonizing frame leaves of all varieties decreased to nearly zero late in the season, and no differences in preference among leaf disks from the heads of the four varieties were observed.
Effect of cruciferous glucosinolates on probing pattern and feed uptake by mustard aphid,Lipaphis erysimi (Kaltenbach)
TLDR
The glucosinolate content of the 3 host plants, viz. yellowsarson, Chinese cabbage, Brassica campestris L.pekinensis andtaramira, differed qualitatively as well as quantitatively mainly with respect to allyl-, methylthiobutyl, pent-4-enyl, methyl- and benzyl-glucosinolates.
Progress in Understanding and Sequencing the Genome of Brassica rapa
TLDR
The current understanding of the genome structure of B. rapa is reported and efforts for the whole-genome sequencing of the species are reported, which will offer a new perspective for plant biology and evolution in the context of polyploidization.
Antixenosis–A New Term Proposed to Define Painter's “Nonpreference” Modality of Resistance
TLDR
Reginald Painter proposed that plant resistance, as observed in the field, could be explained by three fundamental mechanisms which he named: (a) nonpreference, (b) antibiosis, and (c) tolerance.
