Agronomic potential of 18 F6 bean lines in Ecuador

Abstract:

The aim of this research was to evaluate the potential agronomic of the 18 lines F6 of bean during the years 2010 and 2011, in the Guayas river basin. Commercial variety lNlAP-473 and 18 lines promising F6 of the crossbreeding Cf6 (all of habit growth determinate type Ia) were used. Randomized complete block design we used with 19 treatments and 3 replications. We quantified the number of emerged plants, days to flowering, flower color, plant height and inserting of pod, intensity of complex of foliar diseases, and separately the rust (Uromyces apendiculatusPers.:Pers.), web blight [Rhizoctonia solani(Kuhn)] and viruses [Bean common mosaic virus(BCMV)], and the number of pod per plant, fresh grain weight and grain yield. For comparison between treatment means was used Tukey’s test (p<0,05), and for comparison between years we used the Student’s t-test (p<0,05). Cf6 0-0-5-2, Cf6 0-0-7-2 y Cf6 0-0-7-7 promising lines were betters agronomic, sanitary and productively.
