quantifying factors determining seed weight in open pollinated and hybrid oilseed rape (brassica napus l.) cultivars
seed weight (sw) in oilseed rape (brassica napus l.) is determined during the seed filling period (sfp). a great proportion of variation in sw is associated with environmental conditions in this period. to quantify factors determining sw in open pollinated (op) and hybrid cultivars of oilseed rape, 12 field experiments were conducted at agricultural research station of gonbad, iran, during 2000...
متن کاملPerformance of a local open pollinated maize variety and a common hybrid variety under intensive small-scale farming practices
Given that the majority of maize farmers in Kenya are small-scale, improvement in maize production must focus on increased production per unit area. While hybrid maize varieties outperform local open pollinated varieties under conventional farming practices, their relative performance has not been tested under small-scale intensive production practices. A study was conducted in 2013 in Kitale, ...
متن کاملComparison of Open-pollinated and Hybrid Onion Varieties for New Mexico
Eighteen hybrid onion and 23 open-pollinated (OP) varieties were tested in southern New Mexico for plant characteristics, disease resistance, and bulb yield in order to determine if hybrid varieties outperformed OP varieties. Varieties were shortto intermediate-day in their bulbing response and were planted in the fall seasons of 1997 and 1998 and harvested the following May or June. Varieties ...
متن کاملReactions of Open-Pollinated Sweet Corn Cultivars to Stewart’s Wilt, Common Rust, Northern Leaf Blight, and Southern Leaf Blight
The first commercially successful F1 hybrid sweet corn, Golden Cross Bantam, was released by Smith in the early 1930s (17). Today, over 600 sweet corn hybrids are available commercially in the United States and thousands of new hybrids are developed and evaluated each year. These hybrids display a wide range of phenotypic reactions to prevalent diseases (9), indicating a considerable amount of ...
متن کاملMaize plants infestation by Fusarium spp. and deoxynivalenol in genetically modified corn hybrid and traditional maize cultivars.
The objective of the performed investigations was to isolate pathogenic fungi from contaminated maize cobs, to assess the appearance of maize cob fusariosis and to determine grain contamination with deoxynivalenol in the cultivation of genetically modified maize containing a gene resistance against European corn borer (Ostrinia nubilalis Hbn) as well as selected non-modified cultivars. The plan...
