To address this challenge, 20 diverse wheat genotypes, including two regional checks (Shalimar Wheat-1 and Shalimar Wheat-2), were evaluated across five cropping seasons (2020–2025) under temperate field conditions at Wadura, SKUAST-Kashmir. Eight key agro-morphological traits—days to 50% flowering, days to maturity, plant height, spike length, spikelets per spike, grains per spike, estimated grain yield, and thousand-grain weight, were assessed to quantify phenotypic and genetic variation. Pooled ANOVA revealed significant effects of genotype, environment, and genotype × environment interaction for most traits, highlighting substantial diversity and environmental influence. Considerable phenotypic variation was recorded across all traits. Genotypes WW-103, WW-101, and WW-102 consistently exhibited the earliest flowering and maturity, with WW-103 achieving the highest yield (4.69 t ha⁻¹), outperforming the checks. PCV values exceeded corresponding GCV values, indicating environmental modulation, while high heritability (76.97 to 97.37 %) confirmed strong genetic control. Positive correlations among spike-related traits and yield emphasized their importance under temperate conditions. Overall, WW-101, WW-102, and WW-103 show strong potential as early-maturing, high-yielding candidates suited to the Kashmir Valley’s cold-prone climate and for strengthening rice–wheat cropping system adoption.","PeriodicalId":497869,"journal":{"name":"Journal of Cereal Research","volume":"17 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://epubs.icar.org.in/index.php/JWR/article/download/173921/64454","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inter alia, wheat producers have been advocated to adopt the recently released high yielding rust resistant wheat varieties to counter the significant yield losses. In the milieu, we investigated the technological trend in seed indent followed by policy options for the transfer of technology at farmers’ fields. Research findings indicated that the wheat producers adopted old varieties. In the recent past five years, the trend hasn’t witnessed any drastic change despite several rust-resistant varieties having been tested and released for various agro-climatic conditions. Recent varieties take about 5 years to reach their peak adoption since release which is attributed to the innovative transfer of technologies. At the producers’ level, technologies (varieties) have been upscaled through frontline demonstrations, especially in cluster mode. Demonstrations resulted in an average yield gain of 699 kg/ha for innovative rust-resistant technology (HD 2967) compared to its check. Despite the increasing demand and promotion of the latest technologies, the need and availability of ‘producer choice variety’ is persisting and has to be addressed. Innovations like ‘community seed banks’, strengthening public-private partnerships, contract farming (quadpartite model), participatory demonstrations, and blockchain-enabled ‘seed tracker’ will strengthen the transfer of technology system in Indian wheat production.","PeriodicalId":497869,"journal":{"name":"Journal of Cereal Research","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135671778","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}
