Physiological Mechanisms behind Differences in Pod Shattering Resistance in Rapeseed (Brassica napus L.) Varieties
Pod shattering resistance index (SRI) is a key factor affecting the mechanical harvesting of rapeseed. Research on the differences in pod shattering resistance levels of various rapeseed varieties can provide a theoretical basis for varietal breeding and application in mechanical harvesting. The indicators on pod shattering resistance including pod morphology and wall components were evaluated ...
متن کاملCombining Ability Analysis of Yield Component Parameters in Winter Rapeseed Genotypes (Brassica napus L.)
Eight winter rapeseed genotypes GA096, Geronimo, Okapi, Orient, Sunday, Zarfam, SW0756, and Modena were used as parents of a complete diallel mating design. A set of 56 diallel F1 hybrids (with reciprocals) including their parents were evaluated in a 8×8 simple lattice design with two replications during 2007/08. Several agronomic traits like Plant height, number of lateral branches per pod, nu...
متن کاملcombining ability of quantitative and qualitative traits in rapeseed (brassica napus l.) varieties at two nitrogen levels
the combining ability of quantitative and qualititative traits has been studied quite frequently in rapeseed (brassica napus l.), but rarely at different nitrogen levels. twenty-one genotypes, including 6 parents and their 15 f2 diallel progenies, were evaluated at two nitrogen rates, n0 and n150. a combined analysis of variance revealed significant mean squares of general (gca) and specific (s...
متن کاملDetection of Fungus Infection on Petals of Rapeseed (Brassica napus L.) Using NIR Hyperspectral Imaging
Infected petals are often regarded as the source for the spread of fungi Sclerotinia sclerotiorum in all growing process of rapeseed (Brassica napus L.) plants. This research aimed to detect fungal infection of rapeseed petals by applying hyperspectral imaging in the spectral region of 874-1734 nm coupled with chemometrics. Reflectance was extracted from regions of interest (ROIs) in the hypers...
متن کاملHeritability and genetic advance in rapeseed (Brassica napus L.)
The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...
