Diallel analysis of cucumber germination at optimum and suboptimal temperatures
Cucurbit Genetics Cooperative Report 16:22-26 (article 8) 1993 P. Milotay Vegetable Crops Research Institute, 6000 Kecskemet, P.O.B. 116, Hungary Germination of cucumber seeds under cool weather conditions is frequently erratic resulting in poor, or non-uniform emergence. cucumber seeds germinate rapidly between 20-30C, however there is a sharp reduction in germination percentage and initial seedling development […]
Independence of fruit length and 10 other characters in cucumber
Cucurbit Genetics Cooperative Report 16:18-21 (article 7) 1993 Nick E. Fanourakis Technical Educational Institute, Heraklion Crete 71500, Greece Fruit length of cucumber exhibits great variability. Although the inheritance of fruit length has been investigated, data are not comparable because of the varying germplasm sources used and the collection and analysis measure applied (2, 3, 4, […]
