“…Ghasolia et al (2004) [4] reported the similar outcomes that the white rust disease incidence vary from place to place and time to time in different areas of Rajasthan and found diseaseincidence between 40-60% in some districts, 20-39% in other districts and less than 20% in other districts. Yadav et al (2018) [7] also found the similar results in survey that the disease intensity vary among all the surveyed areas and found in range of 19.76-32.79% in different areas of Madhya Pradesh. were grown, disease incidence was recorded and it was observed that the incidence of the diseasediffered across all of the surveyed areas because of the prevailing congenial environmental conditions and aggressive pathogen factors.…”

A roving survey was conducted during Rabi 2020-21 and Rabi 2021-22 seasons to observe natural occurrence of white rust disease of rapeseed-mustard caused by Albugo candida Kuntze prevailing in Agro-Climatic Zone-I of Bihar viz. Muzaffarpur, Samastipur, Darbhanga and Vaishali district. The presence of incidence of the disease in all the places were observed during survey and differed across the surveyed areas because of the prevailing congenial environmental conditions and pathogen factors. The white rust incidence were varied between 15.5 to 20.3%. It was found that the mean per cent disease incidence was maximum in the district of Muzaffarpur (20.3%) and minimum in the district of Vaishali (15.5%). From survey report, it had been concluded that in previous years white rust disease was considered as minor disease but due to changing climate it was prevailing in all the areas in Agroclimatic Zone-I conditions and the incidence of the disease was increasing with time in Bihar.

“…Likewise, five genotypes, including BEC-144, Heera and BIO YSR of B. juncea were found highly resistant at true leaf stage under field conditions [32]. Similarly, Yadav et al [33] reported 27 Indian mustard germplasm accessions with resistance reaction at Hisar, Ludhiana and Pantnagar under field conditions and eight of them were identified as highly resistant to "Delhi isolate" of A. candida at both cotyledonary and true leaf stages under artificial conditions. In the present study, four genotypes (PDZ-1, PDZ-4, PDZ-5, EC-399299) were resistant at true leaf stage under field conditions but were susceptible at cotyledonary stage under controlled conditions, highlighting that there is no chance for the seedlings to escape from the disease infection in controlled conditions where proper temperature and humidity were maintained, which is highly congenial for disease development.…”

Inheritance and Allelic Relationship among Gene(s) for White Rust Resistance in Indian Mustard [Brassica juncea (L.) Czern & Coss]

et al. 2022

White rust [Albugo candida (Pers. Ex. Lev) Kuntze] is an important oomycetes disease of Indian mustard [Brassica juncea (L.) Czern & Coss] that causes a drastic reduction in seed yield and quality when the conditions are favorable. A set of 25 Indian mustard genotypes were screened against A. candida Delhi isolate (Ac-Dli) under both controlled and natural epiphytotic conditions. Out of 25, only six genotypes (Pusa Karishma, PDZ-3, Heera, BEC-144, BIO YSR, and Donskaja) were found highly resistant in both environments. To study the inheritance of resistance, four resistant genotypes (BEC-144, BIO YSR, Pusa Karishma, and Donskaja) were crossed with three susceptible genotypes (PM-24, Pusa Vijay, and MSTWR-17-15) in a definite design. The parents, F1, F2, and BC1F1 (F1 backcrossed with susceptible parent) generations were screened under both artificially controlled and natural epiphytotic conditions and the results indicated that the resistance in BIO YSR, BEC-144, and Pusa Karishma is governed by a single dominant gene, but more than one dominant gene is responsible for resistance in Donskaja. A test of an allelism conducted on the F2 population derived by crossing resistant (BEC-144) × resistant (BIO YSR) genotypes indicated that the gene imparting resistance to Ac-Dli isolate in the resistant parents BEC-144 and BIO YSR is the same and they are allelic to each other. Therefore, in broader terms, the information generated in the present study will be useful in Indian mustard breeding programs for the development of durable resistant cultivars.

“…Thus, they were better adapted to low nitrogen fertilizer conditions. In mustard germplasm with such a significant differences for traits plant height, number of branches per plant, number of siliques in main branch, 1000 seed weight, stover yield and seed yield might be due to the differences in their genetic background (Yadav et al 2018). On the other hand genetic and environment interaction also affect performance of accessions under various doses of nitrogen fertilizer (Khoshanazar et al 2000, Kolte et al 2000, Stringam et al 2000.…”

Response of Indian mustard (Brassica juncea) germplasm grown under low nitrogen conditions

et al. 2022

View full text Add to dashboard Cite

Brassicas are highly responsive to N application and require relatively high rates of mineral N fertilizers for optimum seed yields. Present study was carried out at the Experimental Farm of ICAR-National Bureau of Plant Genetic Resources, Pusa Campus, New Delhi, India during 2015â€“16 and 2016â€“17. Forty five accessions of Indian mustard were tested under three different nitrogen fertilizer rates i.e. Control (0 kg/ha), moderate (40 kg/ha) and optimal (80 kg/ha) to determine the performance of Indian mustard (Brassica juncea (L.) Czern.). The results showed that with increase in nitrogen fertilizer rate seed test weight, oil content, stover yield, seed nitrogen uptake, total nitrogen uptake, seed uptake efficiency, nitrogen use efficiency and seed yield also increased. However, some accessions performed better under low nitrogen condition. For example, IC267538, IC311819 showed more plant height under zero N-fertilizer application as compared to high N dose. Out of 45 accessions, 36 showed more no. of branches at zero N dose. Accession IC571402 was the best performer under zero N dose as it showed superiority for 8 different traits, viz. no. of branches/plant, test weight, oil content, N% in plants, N% in seed, total N%, grain uptake efficiency and Nitrogen Harvest Index. Similarly, accessions IC424415 and IC571654 performed well for 7 different traits. A set of Brassica juncea germplasm which performed better under low N fertilizer conditions were identified. These nitrogen use efficient accessions would be useful for breeders/researchers to develop varieties of mustard for low nitrogen usages.
