Czern & Coss] is an important Rabi season oilseed crop, belongs to family Cruciferae and genus Brassica. Indian mustard is a natural amphidiploid (2n=36) a cross between Brassica rapa (2n=20) and Brassica nigra (2n=16). Mustard is largely self-pollinated but certain amount (2-14%) of cross pollination may take place and is mainly grown in northern part of India. Rajasthan contributes 44.60 % in area & 52.05 % in production of total rapeseed-mustard of India. Mustard crop required lower water requirement (240–400 mm) for completing life cycle, therefore it is fits well for rain fed cropping systems. Four oleiferous brassica species viz. Brassica juncea, Brassica napus, Brassica rapa and Brassica carinata are cultivated in about 6.2 International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 10 (2020) Journal homepage: http://www.ijcmas.com","PeriodicalId":121191,"journal":{"name":"Crop Research Hisar","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131337555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monech] is the fifth most important cereal crop worldwide after wheat, rice, maize and barley (FAO, 2011). In Maharashtra, sorghum is being grown on 5.50 million hectares and production is 6.05 million tonnes. sorghum shoot fly, Atherigona soccata Rondani (OrderDiptera, FamilyMuscidae) is the most destructive one and causes severe damage in the early i.e. seedling stage and last up to 4 weeks causing severe reduction in plant population thereby causing heavy yield losses. The maggot crawls to the plant whorl and then moves downward between the fold of young leaves till they reach the growing point. It cuts the growing tip and feeds on the decaying leaf tissues, which results in dead heart formation. Resistance to shoot fly, A. soccata in sorghum is expressed in terms of antixenosis for ovipositon, antibiosis and tolerance (Sharma and Nwanze, 1997; Dhillon et al., 2005 a, b).","PeriodicalId":121191,"journal":{"name":"Crop Research Hisar","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121468633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
