Genomic tools for watermelon breeding are becoming increasingly available. A high throughput genotyping system would facilitate the use of DNA markers in marker-assisted selection. DNA extraction from leaf material requires prior seed germination and is often time-consuming and cost prohibitive. In an effort to develop a more efficient system, watermelon seeds of several genotypes and various s...

changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. for genetic studies, it is essential t...

Potato is one of the staple crops cultivated in upland farming in Japan and is propagated vegetatively by means of tubers. However once infected with diseases, potato yield decreases significantly. And one seed potato can produce approximately only 10 potato tubers. To improve the production system of seed potatoes in Japan, Japanese government established a three-stage propagation system for t...

IInstitutional analysis can be used to understand the value placed on crop diversity by farmers as a social process, and to uncover the market-related constraints and incentives that influence farmer management of genetic resources. This is particularly important for capturing the dynamics of crop populations and the collective impact of individual decisions regarding crop diversity. In the app...

In this work we consider the simultaneous solution of large linear systems of the form Ax(j) = b(j); j = 1; : : : ; K where A is sparse and non-Hermitian. Our single-seed approach uses QMR to solve the seed system j and generate biorthogonal Krylov subspaces. Approximate solutions to the non-seed systems are simulanteously generated by minimizing their appropriately projected residuals. After t...

After harvesting wheat, the main concern is classifying wheat seeds according to their quality, size, variety and etc. there are different procedures to measure parameters and analyzing wheat seeds but they are time-consuming and error-prone. An automated system is developed being capable to analyze and classify wheat seeds faster with higher confidence level based on defined attributes, the sy...

Since the 1980s, many developing countries have introduced policies to promote seed industry growth and improve the delivery of modern science to farmers, often with a long-term goal of increasing agricultural productivity in smallholder farming systems. Public, private, and civil society actors involved in shaping policy designs have, in turn, developed competing narratives around how best to ...

Granivorous animals may prefer to predate or cache seed of certain plant species over others. Multiple studies have documented preference for larger, non-native seed by granivores. To accomplish this, researchers have traditionally used indirect inference by relating patterns of seed removal to the species composition of the granivorous animal community. To measure seed removal, researchers pre...
