Participatory Variety Selection

Field pea is one of the grain food legumes contributing an enormous amount of protein to the human diet in Arsi zone. It is a long time ago that fi eld pea crop improvement started in which more than 16 new varieties released those are selected primarily for yield potential, but there is a trait left considered as a very import by majority of farmers. The current study intended to identify traits that farmers consider most important when deciding which varieties to grow. The study was conducted at south eastern Arsi of Ethiopia, representing fi ve major fi eld pea producing location, in one growing season, using a participatory variety selection approach. A total of nine improved and one local check fi eld pea varieties are used. Majority of farmers’ were found around fourteen traits that can infl uence the selected varieties across all locations. There are also some traits those are more sensitive to gender diff erence. Among fourteen traits, nine were considered particularly important in one or all the location in a growing season. Unfortunately, there are preferred traits that are not given high priority by the current fi eld pea breeding program in Ethiopian. This study indicated that there is no fi eld pea variety possesses all desirable characteristics that meet the diverse farmers’ selection criteria that adapted to varied location and a growing season. It is better if farmers’ preference traits would be considered in breeding program for a country Ethiopia where the crop is consumed as a stable food.

This study was conducted to identify suitable parental genotypes for breeding for resistance to bruchid and to identify the farmers’ preferred traits in common bean. For this study, 144 diverse common bean genotypes were planted in an alpha lattice design, with 3 replications at 3 locations. Participatory variety selection was done using 20 farmers at each location. Farmers identified a number of criteria for selecting suitable varieties. Yield and yield-related traits were ranked as the most important selection criteria by all farmers at all locations. However, women ranked culinary traits as the top criteria, while men were more interested in marketable traits. From the 144 genotypes, farmers selected the 10 best genotypes in all the locations. The majority of the genotypes selected at Melkassa and Alemetena were small white-seeded released varieties and breeding lines. However, all the genotypes selected at Arsi Negele were predominantly landraces of small red-seeded beans. Traits such as earliness and resistance to storage insect were important in Melkassa and Alme tena but received less attention in Arsi Negele. The integration of the farmers’ selection preferences with the breeders’ criteria can improve the efficiency of plant breeding by developing crop varieties that better fit the specific needs of the farmers.

Uniform imbibition and germination of field pea (Pisum sativum L.) seeds is very important for sprout production for human consumption. The imbibition and germination of 3 cultivars of field pea, Dunwa, Dundale, and Helena, each grown at Mullewa, Merredin, and Scaddan in the grainbelt of Western Australia, were investigated in laboratory experiments. The ability of field pea to germinate was affected by cultivar and the environment under which seed development occurred on the parent plant. Averaged over locations, germination of the cv. Dundale (82%) was lower than of Dunwa (93%) or Helena (95%). Germination of seeds ranged from 85% for those grown at Merredin to 91% at Scaddan and 94% at Mullewa. The effect of growing location on germination was most pronounced in cv. Dundale from Merredin where the largest number of hard seeds was observed. Initial seed water content was positively (r2 = 0.55*) correlated with germination across cultivars and sites. Small and large seeds within a seed lot with the same initial seed water content had a similar germination percentage. During imbibition, water entered the seed through the strophiole and this would be an appropriate place to look for a mechanism that affects imbibition. Careful selection of cultivar and favourable growing site should improve germination for the sprout producer.

Participatory Variety Selection

Participatory variety selection (PVS) was carried out in two of the major tef-growing woredas (districts) of Ethiopia, Ada and Akaki, in 2003 and 2004. The objectives were to identify farmers' selection criteria, to increase farmers' awareness and their access to improved tef varieties, to enable farmers to assess the performances of improved tef varieties of their choice and to accelerate seed dissemination of farmers' chosen varieties through farmer-to-farmer exchange mechanisms. Seed colour was the overriding selection criterion. Farmers overwhelmingly selected the very white seed variety DZ-01-196 (Magna) for market purposes, indicating that tef is a cash crop. Farmers also selected brown-seeded tef, but for home consumption. There was no evidence of connection between seed colour and desirable agronomic traits, or nutritional quality (protein content). Factors other than seed-colour were of secondary concern to farmers. When market demands become the dominant selection criteria, PVS should not be an end by itself: rather, it complements the formal breeding system. The results imply that tef performance evaluation trials need to be separated on a colour-group basis, and any new successful variety in the two woredas should be superior to DZ-01-196 not only in grain yield but also in seed-colour quality. A faster, more efficient and reliable pure-seed supply system than the traditional farmer-to-farmer exchange mechanism is required in order for farmers to continue planting improved varieties, which might be better achieved through small-scale commercial producers and/or cooperatives.
