Scarcity of water for irrigation is an alarming issue of Pakistan and the problem is being magnified rapidly with the passage of time. Shortage of water is thus, a limiting factor in increasing per unit area wheat (Triticum aestivum L.) yield that is staple food of most of the people. Eventually, the gap between production and consumption is widening day by day and Pakistan is now suffering fro...

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...

Mulberry is an important crop for the sericulture sector because they are main source of nutrition silkworms. Sericulture practice raising silkworms to produce silk, which a valuable and opulent textile in many industries. primary food silkworms, hence availability quality mulberry crucial industry. Therefore, development improved varieties essential enhancing silk production. Attempts were mad...

In perennial energy crop breeding programmes, it can take several years before a mature yield is reached when potential new varieties can be scored. Modern plant breeding technologies have focussed on molecular markers, but for many crop species, this technology is unavailable. Therefore, prematurity predictors of harvestable yield would accelerate the release of new varieties. Metabolic biomar...

Abstract Background High-yielding variety (HYV) seed breeding has been one key approach to improving agricultural productivity and reduce global hunger poverty. This paper explores the causal relationship between high-yielding rice variety, productivity, farm income household nutrition. A challenge with evaluating impact of changes such as crop varieties on yield is self-selection endogeneity. ...

Crop improvement is the fundamental goal of plant biologists, and genetic diversity base for survival plants in nature. In this study, we evaluated 20 wheat lines morphological using eight simple sequence repeats markers from Wheat Microsatellite Consortium (WMC). Morphologically, variations were observed among all different studied trait except single spike weight. The highest values agronomic...

Researchers and policymakers are concerned about the substantial increasing yield gap between sub-Saharan Africa rest of world. High-yielding improved varieties widely perceived as a means to close this gap. This study combines impact evaluation production analysis techniques, which mitigate estimation biases stemming from observed unobserved heterogeneity, estimate effects on maize productivit...

Kuga-Satake varieties are abelian varieties associated to certain weight two Hodge structures, for example the second cohomology group of a K3 surface. We start with an introduction to Hodge structures and we give a detailed account of the construction of Kuga-Satake varieties. The Hodge conjecture is discussed in section 2. An excellent survey of the Hodge conjecture for abelian varieties is [...

Traditional breeding for high-yielding rice has been dependent on the widespread use of fertilizers and the cultivation of gibberellin (GA)-deficient semi-dwarf varieties. The use of semi-dwarf plants facilitates high grain yield since these varieties possess high levels of lodging resistance, and thus could support the high grain weight. Although this approach has been successful in increasing...
