the cultivar khavaran has come out of the national potato breeding program started in 2001 and continued for ten years in the seed and plant improvement institute karaj, iran. the breeding methodology has initiated by selection among germplasm consisting an open pollination of the clone 397097-13. the khavaran release included single plant selection, visual assessment, preliminary observation n...

Landraces are heterogeneous populations and their variability goes through continuous alterations because of physical, genetic, and epigenetic procedures exacerbated by the ongoing climatic changes. Appropriate stewardship of landrace diversity is pivotal to promote its longevity in a manner that is sustainable from the farming perspective. A seed multiplication procedure is presented based on ...

Drought is considered as one of the critical abiotic stresses affecting growth and productivity upland rice. Advanced rapid identification drought-tolerant high-yielding genotypes in comparison to conventional rice breeding trials assessments can play a decisive role tackling climate-change-associated drought events. This study has endeavored explore potential CERES–Rice model decision support ...

canopy temperature (ct) is used as a selection tool to improve crop adaptation to drought. the aim of this work was to investigate association of some photosynthetic characters with ct during grain filling in three cereal species. for this objective, a two-year study (2009-2011) was carried out in kurdistan province in western iran. four genotypes of triticale, three cultivars of bread wheat, a...

The current study was designed to estimate correlation coefficients and investigate the direct indirect effects of various yield contributing traits on seed in twenty greengram genotypes. experiment carried out during Kharif 2021 a randomized block design with three replications. Correlation studies among characters revealed that per plant has highly positive significant association like height...

Coordinated varietal trials (CVTs) were conducted to identify the high yielding papaya (Carica L.) genotypes at different agro- climatic conditions with eight Agriculture Research Station (ARS), Malepatan, Pokhara; Viuran, Nawalparasi and Parewatar, Dhading during 2006-2009 seedling transplanted time of October experiment was designed in RCBD replicated thrice. Observations recorded on biologic...

Experiment was designed to establish a more defi nitive relationship of phenological and physiological traits with yield in wheat using twenty fi ve spring wheat genotypes. Because many of these traits are interrelated, correlation coeffi cient, path analysis and principal component analysis were used to expose these relationships more clearly. Experiment was conducted at the Wheat Research Cen...
