The study revealed the occurrence of ring spot in Saccharum species as well as in hybrid clones. Other diseases recorded were smut, rust, stalk rot, banded sclerotial disease and YLD. Among these diseases, only few clones such as IJ 76 552 and 28 NG 82 (Saccharum robustum), Co 844 and Co 62175 (Indian hybrids) were affected by smut. Rust is the common disease in the 32 hybrid clones and in four clones of S. spontaneum viz. IND 81-20, IND 81-74, IND 81-82 and IND 81-83. Only one S. officinarum clone IJ 76 501 was affected by rust till now. Stalk rot was observed mostly in S. officinarum clones and in few hybrid clones, respectively during 2017-2019. For the first time, leaf blight due to banded sclerotial disease was noticed in NG 77-145 of S. robustum, Agoul, Baroukha, Chin and Dark Pindaria of S. barberi and IS 76-168 of S. officinarum during 2019.","PeriodicalId":52656,"journal":{"name":"Journal of Sugarcane Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48641633","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}

Varietal identification and characterization is one of the important aspects in any breeding programme. Forty sugarcane clones from Pre -zonal varietal trial (PZVT) conducted at Ugar, North Karnataka were characterized through Simple sequence repeats (SSR) markers using a set of 15 sugarcane specific primer pairs which amplified a total of 164 alleles with an average of 10.93 alleles per pair. Primer NKS 33 was highly polymorphic and produced more than 15 polymorphic alleles and was unique in all the clones studied. Six primers i.e., NKS 2, NKS 6, NKS 7, NKS 40, NKS 42 and NKS 11 were moderately polymorphic by producing 10 to 13 alleles. Percentage of polymorphic bands ranged from 75.0 % (NKS 3) to 100.0 % (NKS 40 and NKS 42). Primers viz., SMC 1039 GC, mSSCIR 54, NKS 2, NKS 7, NKS 9, NKS 33, NKS 40, NKS 42 and NKS 11 were highly informative and generated above 85.0 % of polymorphic bands. Among the primers used, SMC 1039 GC, NKS 33, NKS 42 and NKS 43 produced the maximum number of unique markers in different clones and hence the combined application of these primers will be useful in unambiguous varietal identification. The cluster analysis based on the genetic similarity matrix grouped the 40 clones into two major clusters CI and CII. The largest cluster CII contained the maximum of 38 clones. Cluster C II was further sub-grouped into IIa, IIb, IIc and IId and each sub-cluster comprised 7, 11, 6 and 14 clones respectively. The unique DNA markers and the genetically diverse combinations identified in the present study will enhance the exploitation of genetic diversity present in the clones in breeding programmes and promising twenty eight entries for yield and quality.","PeriodicalId":52656,"journal":{"name":"Journal of Sugarcane Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42916026","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}

In today’s scenario, this means sugarcane growers who produce sugarcane sustainably must benefit from it. The economics of sugarcane cultivation is about finding logical, reasonable means of balancing individual economic self-interest with ecological and social integrity. Despite the increase in area and production of sugarcane, recently some concerns are emerging regarding farm profitability, sustainable use of farm resources and hike in input prices which have a direct and indirect influence on the cost of cultivation of sugarcane. Therefore, the objective is to analyse and compare the economic viability of sugarcane cultivation in major sugarcane producing states of India. The result indicates that the cultivation of sugarcane is profitable for Maharashtra but it involves more risk in terms of relatively less net income, as compared to other states. Moreover, the return per rupee spent was observed positive in both tropical and sub-tropical regions. The Sugar Trap makes the growers to stick with sugarcane cultivation due to some of the benefits received from the sugarcane crop such as relatively high profit, secure market (guarantee of purchase), less chance of crop failure, subsidized inputs, production system is based on contract farming model, etc. The study reports that, due to the longer duration of the crop, there is a hike in operation cost which warrants a technical solution.","PeriodicalId":52656,"journal":{"name":"Journal of Sugarcane Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46028685","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}
