|
| 1 | Species name | Cajanus cajan |
| 2 | Common name | Pigeon pea |
| 3 | Variety name | ICEAP 00554 (Ashenafi) |
| 4 | Plant growth habit | Nondeterminate and semi-spreading. Under intercropping, the plants remain tall and compact, but when grown under a low population, additional branches develop, giving a semi-spreading appearance. |
| 5 | Stem color | Green. |
| 6 | Leaves | Green in color and medium in size. |
| 7 | Plant height | Significantly influenced by temperature. Under warm environments, the plants grow tall but shorter under cool environments. |
| 8 | Days to flowering and maturity | Temperatures above 24oC delay flowering and maturity. At optimum temperature for growth, it flowers and matures in about 95–127 days and 150–187 days, respectively. |
| 9 | Flower color of base petal | Yellow. |
| 10 | The pattern of streaks on a standard petal | No streaks. |
| 11 | Immature pods | Color: dark to pale green with no stripes, shape: long and slightly curved, pod constriction: slight, and seeds per pod: 5–7 seeds |
| 12 | Seed size | Large with a 100-seed mass of 14–18 g. |
| 13 | Seed color | White/cream and uniform in pattern. |
| 14 | Suitability to shelling | The shellability of green pods is excellent, making them highly preferred by farmers. |
| 15 | Dehulling % | It has an excellent dehulling quality of up to 85% and is, therefore, suitable for processing. |
| 16 | Potential yield | Immature and dry grain is 6–10 t ha−1 and 1.8–3.4 t ha−1, respectively. |
| 17 | Suitability to ratoon | Suitable. |
| 18 | Target areas of production | Variety ICEAP 00557 (Ashenafi) is widely adapted across semiarid environments. It is recommended for cultivation in areas with an annual rainfall of (400–900) mm. It grows well at an altitude between 400 and 1800 m above sea level. |
