“…L. erysimi, Brevicoryne brassicae L., and Myzus persicae Sulzer are some of the aphids that harm rapeseed mustard in India. L. erysimi is one of the principal restricting factors, producing major output losses and a decline in oil content [2,3]. It decreases yield by 35.4 to 96%, seed weight by 30%, and oil production by 2.75% [4,5].…”

After soybean and palm oil, the world’s third largest oil seed crop is rapeseed mustard. Out of the seven consumable oil seed crops grown in India, rapeseed mustard is responsible for one-third of production. Mustard aphid (Lipaphis erysimi Kalt) is considered the primary pest causing mayhem in crop production. Understanding the genetics behind resistance will aid breeders in developing a resistant/tolerant strain. Appropriate parent selection and analyzing gene action contribute to economic benefit maximization. The aims of the current study are to use seven lines and five testers to determine the best-performing parents and crosses based on their general and specific capacity to combine and to examine the level of heterosis for yield and related features like mustard aphid resistance. Due to the self-pollination nature of Indian mustard, Kempthorne’s line X tester method is helpful to judge the combining ability. Therefore, seven lines and five testers of Indian mustard (Brassica juncea L.) were employed in the present study. The findings suggested that there was substantial genetic variation for all traits examined. The mean oil yield of R1 B2-26 × R1 B2-25, JD6 × R1 B2-25, and JD6 × R1 B2-29 hybrids was more significant than that of the ancestors. The results show that R1 B2-26 × R1 B2-25, JD6 × R1 B2-25, and JD6 × R1 B2-29 hybrids produced more oil than their parents. The variance explained by SCA was greater than that explained by GCA, as indicated by the Ϭ2 gca/Ϭ2 sca ratio being less than one for all characters, implying that nonadditive gene actions such as dominance, epistasis, and other interaction effects played an important role in the presence of these attributes. Punjab Local was discovered to be an excellent general merge for reducing crop duration, whereas JD6 was an excellent combiner for seed yield per crop, aphid infestation indicator, seed yield per crop, and oil production per plant. The predictability ratio was found to be less than 0.5 for almost all traits, denoting that the nonadditive gene measure is involved in controlling the nature except days to 50% flowering, aphid infestation index, oil content, and oil yield per plant. Thus, based on these four traits, selection for superior plants may be practiced in later generations.

“…Among these pests, the mustard aphid is particularly damaging, causing yield losses ranging from 24.5 to 68.00 per cent (Kular and Kumar, 2011;Sharma et al, 2019;Kumar, 2017), with reported oil losses of 3.38 to 8.14 per cent (Sharma, 2019), resulting in a staggering 97.40 per cent yield loss. Crocidolomia binonalis is another significant pest responsible for yield reductions ranging from 13.2 to 81.3 per cent (Parmar et al, 2007).…”

M.P.) to assess the resistance of various mustard varieties against mustard aphid (Lipaphis erysimi Kalt.). None of the tested varieties exhibited resistance to aphids. Rohini and Pusa-26 varieties showed moderate resistance to mustard aphids. Pusa mahak, Tejasui, Sarita-333 and RVM-2 were moderately susceptible, while Kranti and Kala Sona were deemed susceptible to aphid infestation. Rohini was identified as the least preferred host for mustard aphids, while Kranti and Kala Sona were identified as the most preferred hosts. In terms of yield reduction caused by aphid infestation, Kranti exhibited the lowest yield and the highest yield loss. Conversely, Rohini produced the highest yield and experienced the least yield loss, making it a suitable choice for commercial mustard cultivation in Madhya Pradesh.

An experiment was conducted during Rabi 2008-2009 and 2009-2010. Aphid appeared in first week of January when the maximum temperature was (15.8-16.1 0 C) and minimum temperature (5.3-8.0 0 C) along with relative humidity 93.0-95.3 per cent maximum, 66.0-82.9 per cent minimum and wind speed 2.6 km/h during 2008-09 and 2009-10, respectively. The peak intensity of aphids on different varieties of Indian mustard during 7 th standard week (Feb., 12-18) in respective years, when the temperature was 23.1-25.1 0 C maximum and 9.4-12.5 0 C minimum along with relative humidity maximum 89.0-91.0 per cent and minimum 43.0-69.0 per cent during 2008-09 and 2009-10, respectively. The aphid population was completely wiped out from mustard crop in the last week of February and first week of March, when the crop age was 118 days. At this stage, temperature was 29.7-31.7 0 C maximum and 12.7-15.7 0 C minimum along with relative humidity maximum 73.0-78.0 per cent and minimum 34.0-36.0 per cent during 2008-09 and 2009-10, respectively. Simple correlation coefficient of aphid with weather factors showed a positive relationship with temperature (r=0.226-0.645 and 0.900-0.961) and wind speed (r=0.434-0.651 and 0.599-0.684), while negative impact with relative humidity (r=-0.579 to-0.765 and-0.526 to-0.633) during both the years.
