Abstract

The field experiment was conducted at two districts of Buno Bedele zone (Bedele & Dabo Hana) and one district of Ilu Aba Bor zone (Bure) in southwestern Oromia for two years (2023-2024 G.C). The objective of this study was to select adaptable, stable, higher yield and disease resistant small white common bean varieties. In the experiment, six improved small white common bean varieties and one local check were laid out in randomized complete block design (RCBD) with three replications. Phenological, growth, yield and yield related traits data were collected and analyzed by R-software. Grain yield and yield related traits were significantly affected by main effect of variety, environment and variety-environment interaction. The results revealed that, there were significant at (p < 0.001) variations between the varieties for yield, number seed per pod and days to maturity whereas significant at (p<0.01) for days to flowering, plant height and number of pod per plant. Thus, higher grain yield was recorded from Awash mitin (2330.51 kgha-1) followed by Wabero (1878.11 kgha-1), while lower grain yield was recorded from Awash-1 (1261.36 kgha-1). The AMMI analysis shown that 14.92% of the total sum of squares (SS) was contributed to environments (E), 25.76% to the genotypes (G) and 23.08% to GEI effects. Principal component 1 and 2 accounted for 73.80% and 15.01% of the GEI respectively with a total of 88.81% variation. Therefore, as compared to the others, those two small white common bean varieties were recommended as promising varieties to the farmers of study areas.

Introduction

Common bean (Phaseolus vulgaris L; 2n= 22) is a diploid selfpollinated plant that goes to the genus Phaseolus in the Fabaceae family [1], which has more than 80 cultivated and wild species in the world [2]. Common bean is the most vital food and cash crops worldwide [3]. Common bean is very favored by Ethiopian farmers because of the possibility of maturing by around two months that enables households to get cash returns vital to pay for food and other household needs when other crops have not yet matured [4]. Early maturity and moderate degree of drought tolerance led the crop’s vital role in farmers’ strategies for risk aversion in drought prone lowland areas of the country [5].

In Africa, the major common bean producing countries include Burundi, DR Congo, Ethiopia, Kenya, Rwanda, Tanzania and Uganda, indicating that East Africa is the most suitable bean production region on the continent [6,7]. Common bean is the most broadly cultivated in Ethiopia which covered 18.6% of land with 17.3% of grain production from pulse crops produced in 2021 [8]. In Ethiopia, common bean covered about 339,350.34 hectares of land and 584,157.99 tons of grain was produced per annum in 2022 with average productivity of 1.72 tons per hectare [9]. As the demand of common bean production is increasing in alarming rate, the area of production increasing from 280,834.99 ha in 2020 to 339,350.34 ha in 2022 [9].

There are widespread kinds of common bean types grown in Ethiopia including mottled, red, white and black varieties [10]. The most profitable varieties are pure red and pure white color beans and these are fetching the most commonly grown types with increasing market demand [11]. Among zones in south-western Oromia, the production of common bean is concentrated in the lowlands of Buno Bedele and Ilu Aba Bora zones, specially Dabo Hana, Bedele and Bure districts due to the presence suitable environments to this crop. However, lack of improved varieties of small white common bean is the major problem for low production and productivity of the crop in the study areas. Therefore, the study was initiated to identify and recommend suitable high yielder and disease tolerant small white common bean varieties for the study areas and similar agro ecologies in south-western Oromia, Ethiopia.

Materials and Methods

Experimental Site

The experiment was conducted under rain fed condition at Bedele, Dabo Hana and Bure districts which are far 483 km, 521 km and 683 km from Addis Ababa respectively during 2023 and 2024 main cropping season. These locations represent the major common bean producing areas of South-western Oromia regional state (Table 1).
