Drastic impact of climatic variability demands suitable solutions including adaption through climate-proof cropping system. Similar intervention was focused through the subject study conducted during winter 2019 to assess cultivation of exotic USDA safflower accessions under various environments of Punjab, Pakistan. Four locations i.e. Bahawalpur, Faisalabad, Kasur and Rawalpindi were selected for cultivation of previously screened six safflower candidate lines in a randomized complete block design with factorial arrangements. Seed yield, oil quality and contents was calculated. Results revealed that the performance of safflower accessions of exotic origin perofmred variably under variety of climates. Safflower accession PI-198990 exhibited the highest seed yield at Kasur whereas, PI-199907reflected the least yield at Bahawalpur. High oil contents were estimated at Faisalabad when compared withother locations under study. However, the maximum accumulation of oleic acid was recorded in safflower planted at Bahawalpur. On the other hand, Rawalpindi sown safflower exhibited the maximum content of linoleic acid. As far the morpho-physiological attributes are concerned, positive and significant relationship of seed yield with number of branches, number of heads and thousand seed weight were recorded whereas, linoleic acid showed strongly negative correlation with oleic acid content. Therefore, it is concluded that environmental variation had significantly influenced safflower yield, oil and fatty acids contents.","PeriodicalId":170011,"journal":{"name":"Journal of Agriculure and Food","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127878058","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}

Treatments comprised different granular insecticides; Cartap 4% G, Fipronil 0.3 G, Mover Plus 4.3 % (fipronil 0.3 % + cartap hydrochloride 4%) and Virteko 0.6 GR (chlorantraniliprole 0.2 % + thiamethoxam 0.4 %) @ 22.0, 20.0, 11.0 and 10 kg ha-1 respectively.

The highest suppression efficacy was recorded with the chlorantraniliprol + thiamethoxam followed by fipronil + cartap hydrochloride against plant hoppers and stem borers. Experimental units treated with chlorantraniliprol + thiamethoxam showed the lowest hopper infestation (9,11 and 8 hoppers per plant) as compared to control where 70, 75 and 68 hoppers per plant was recorded for location I, II and III, respectively. Granular insecticide i.e. chlorantraniliprol + thiamethoxam also reduced the stem borer infestation @ 76, 81 & 78 % at location I, II and III respectively.

Commercial cultivar is an advanced line of “FRI-03” which is derived from cross of parental accessions (No. 668 × No. 632) and subsequent selections in various segregating populations (F2 - F6), through pedigree methods having uniformity > 99%. Cultivar had 9% and 15% forage yield advantage over commercial check “Sargodha-Oat 2011” during 2014 and 2015 station trials while it gave 9% higher fodder yield during 2016-17 during zonal trials over commercial check.. It is green, tall, multi-tillering, with slight later in maturing cultivar and produce light brown seed. It has many desirable forage quality traits, including high palatability (82%), protein content (10%) and had resistance to biotic and abiotic stresses. It flower about 10 days later than standard check variety. Moreover, it has higher stability (coefficient of regression bi = 1.06) calculated over 3 environments for 2 years. Its robust yield combine with high palatability and high protein contents than standard check and resistance to biotic and abiotic stress show that Super Green Oat will be highly useful cultivars in both irrigated and arid region of Punjab Province. Moreover, the cultivar will be potential parent for the development of new pedigrees for the genetic improvement of oat germplasm.","PeriodicalId":170011,"journal":{"name":"Journal of Agriculure and Food","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123748730","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}
