Abstract: Aiming at existing problems of kidney bean production in Dalian area, such as cultivarshomogenization, low unit output, serious diseases and insect pests in continuous-cropping area, in orderto select suitable kidney bean cultivars for cultivation and people's taste in Dalian area, 7 main-cultivatedkidney bean cultivars were chosen in this cultivars contrast test, and their performances in terms of growthperiod, botanical traits, commercial pod traits, disease resistance, yield and nutrients were compared. Results indicated that 'Liannong 923' had the earliest date of harvest, the lowest node of blooming and a higheryield, but it was susceptible to rust; 'Liannongwujin No. 6' and 'Liannongwujin No. 2' both had vigorous growth, more branches, and medium resistance to rust; 'Liannong 97-5' belonged to mid-maturity cultivar, and its thousand-grain weight was large while its resistance to rust was medium; 'Liannongtenen No. 5'was the white pod series without ribs of pods, and it matured earlier without resistance to rust while itsyield was low; 'Liannongjiadou No. 10' matured earlier, and it had the highest yield, high resistance to rust,and outstanding quality; the commodity pods of 'Liannongzixia No. 1' were purple and contained higheranthocyanin, which could meet the public demand for special vegetables, but this cultivar was susceptible torust; all experimental cultivars were not resistant to anthracnose. |
