Adaptability Identification and Comprehensive Evaluation of New Pea Varieties(Lines)in Tangshan Area
摘要
Abstract
In order to solve the problem of single variety in pea production,field identification experiments and multi-objective decision evaluation models were used to conduct 2-years trait identification and comprehensive evaluation of 13 new pea varieties(lines),and to screen for suitable new pea varieties(lines)for local planting.The results showed that the plant height of 13 pea strains ranged from 39.8 to 124.6 cm,the number of pods per plant ranged from 4.3 to 9.7 cm,the number of grains per pod ranged from 3.9 to 7.2,the pod length ranged from 4.2 to 8.0 cm,the pod width ranged from 1.0 to 1.4 cm,the weight of 100 seeds ranged from 18.1 to 24.9 g,and the yield per plant ranged from 4.5 to 6.0 g.The coefficient of variation for plant height,number of pods per plant,number of grains per pod,pod length,and yield is above 16%,with the highest coefficient of variation for plant height reaching 36.70%;The yield of all varieties ranges from 2 136.0 to 4 008.5 kg/hm2,with Tangwan 3 and Tang-wan 2 significantly higher than other varieties(lines);Multi objective comprehensive evaluation shows that Tangwan 3 has the best comprehensive traits,while Tangwan 2 and Zhongwan 102 have moderate comprehensive trait performance but high yield.Therefore,Tangwan 3,Tangwan 2,and Zhongwan 102 can be prioritized for demonstration and application in Tangshan City,providing support for the diversification of production varieties.关键词
