To sustain local wine identity in uncertain climate outcomes, the study of intra-varietal diversity is important to reflect adaptive potential cultivated varieties. Findings highlight strong phenotypic studied varieties and importance diversification enhance change resilience. This first step towards quantifying heat requirements different clones how they can provide adaptation solutions for wi...

In smallholder agriculture, women farmers are largely responsible for the selection, improvement and adaptation of plant varieties. In many regions, women are also responsible for the management of small livestock, including their reproduction. Women often have a more highly specialized knowledge of wild plants used for food, fodder and medicine than men. Women – users, preservers and managers ...

Methodological recommendations for lighting modes growing rootstocks and varieties of domestic plum at the stages micro propagation, in vitro rooting ex adaptation determine usage lamps with different light spectra, allowing to obtain more higher results clonal including: height regenerated plants number leaves, propagation ratio; development root system; growth physiological state stage adapta...

This list of the North American vegetable cultivars was developed using the database of cultivars registered with the American Seed Trade Association, as well as published descriptions from scientific journals and seed catalogs. Assistant editors responsible for each crop were instructed to obtain as much information as possible about the cultivars available to North American growers. The crop ...

This study was conducted to determine the stabilities and adaptation classes of edible pea lines, which will be cultivated in mild climate regions. Twenty local lines selected previous breeding studies 6 control varieties were used. The seeds sowed 4 different locations 2 sowing times. experiment according Augmented design. Adaptation determined based on fresh pod yield, seed yield dry yield. m...

We examine the wider social knowledge domain that complements technical and environmental knowledge in enabling adaptive practices through two case studies in Tanzania. We are concerned with knowledge production that is shaped by gendered exclusion from the main thrusts of planned adaptation, in the practice of irrigation in a dryland village and the adoption of fast-maturing seed varieties in ...

A lack of diversity and durability of resistant soybean varieties complicates management of the soybean cyst nematode (SCN), Heterodera glycines, exemplified by the current overdependence on the PI 88788 source of resistance. Of interest is the effect of adaptation of a SCN population to a source of resistance on its subsequent ability to develop on others. Female indices (FI) from virulence as...

Lack of suitable varieties and genotypes of black gram with adaptation to local conditions is among the factors affecting its production. Efforts to genetically improve the crop mostly involve identifying important morphological descriptors followed by development of advanced breeding lines for locale-specific cultivars. The present day available black gram varieties have not been properly char...

Frequent and devastating epidemics of parasites are one of the major issues encountered by modern agriculture. To manage the impact of pathogens, resistant plant varieties have been selected. However, resistances are overcome by parasites requiring the use of pesticides and causing new economical and food safety issues. A promising strategy to maintain the epidemic at a low level and hamper pat...

Whereas disruptive selection imposed by heterogeneous environments can lead to the evolution of extrinsic isolating barriers between diverging populations, the evolution of intrinsic postzygotic barriers through divergent selection is less certain. Long-lived species such as trees may be especially slow to evolve intrinsic isolating barriers. We examined postpollination reproductive isolating b...
