Introduction

What is Cucurbita texana? (a taxonomic/phyletic overview)

What is known about the geographic distribution of Cucurbita texana, especially with respect to the areas where cucurbits are cultivated commercially?

Appendix 1 - base data for mapped distribution

Is Cucurbita texana a weed? Is it a common weed or a serious weed in any localities? What weedy properties does it possess?

Is Cucurbita texana difficult to control? How is it controlled?

What is known about the viability, fertility, and ecological fitness of hybrids arising from crosses of Cucurbita texana and Cucurbita pepo? What impacts on Cucurbita texana might be expected from gene flow from commercial plantings of cucurbits?

How would you design an experiment if you wanted to determine whether virus resistant texana-pepo hybrids were more 'weedy' than the parental species? Would gene copy number, homozygosity, or heterozygosity of the virus resistance gene influence the design or interpretation of results?
