Comparative Experiment of New Rape Varieties in Yangling Agricultural High-Tech Industry Demonstration Zone
摘要
Abstract
Rapeseed is the largest source of edible vegetable oil in China,and the Huanghuai and its Northern Winter Rapeseed Region are one of the important rapeseed production areas in China.The results of the Yangling rapeseed pilot regional trial can better reflect the average results of the entire Huanghuai trial.In order to further improve the yield and quality of rapeseed,accelerate the pace of variety renewal,explore high-quality rapeseed,and improve the economic benefits of farmers,targeted collection of rapeseed varieties from various parts of the country is needed,and conduct experimental demonstrations.The results showed that the incidence rate of sclerotinia sclerotiorum in 2132 and Qinyou 64 was 23.81％,17.46 percentage points higher than that in CK.The plant heights of Qinyou 64,Ronghuayou 369,Qinyou 116,and Qinyou 7(CK)were all higher than 180 cm,indicating poor lodging resistance.Qinyou 2185 had a lower plant height and lower number of effective pods per plant,increasing yield by 6.11％compared to CK;Although the effective number of pods per plant and the number of seeds per pod of Jinyou 256 were lower than those of Yunza 1810,the heteromorphic plant rate,lodging resistance,number of effective branches per plant,thousand seed weight,and yield of Jinyou 256 were better than those of Yunza 1810,and the yield was increased by 25.87％compared to CK,with significant differences and the best comprehensive traits.Therefore,based on the comprehensive performance of various characters,Jinyou 256 can be prioritized for promotion in the Yangling.关键词
