Own Varieties


Spring Forage Peas (Pisum sativum L.) RUSE 1

Ruse 1 variety is with spring type of development, forage peas for grain. Its vegetation period is average 81 days /72–91 days/. It is the same with the vegetation periods of the standards Kristal and Pleven 4 and this variety belongs to the group of the early ripening varieties.


The plants are with middle height, well branched and leafy, with wax coating. The middle height is 61 cm /47-74 cm/ and the height of formation of the first pod is average 35,1 cm /31-47,4 cm/ /table 2/. The lodging is to a low extent and they are suitable for mechanized harvesting.
The leaves are mid-large, compound, paripinnate, green-colored. The stipules are well-developed, mid-large, embracing the stem and the leaf stalk.
The blossoms are large, white, mid-large pedicel, coming out the leaf axil.
The pods are polyspermic – they contain from 4 to 8 seeds. The pods are with smooth surface, mid-long and mid-wide. The degree of the curve is slight, and the type of the curve is concave. During the phase of filling the grain, the pods are green-colored, and during the phase of ripening – straw-yellow. The form in the end is rounded. 14 slightly cracking pods are formed in a plant.
The seeds are large with spherical form. The coating of seeds is light cream-yellow colored, and the cotyledons are yellow. The number of seeds in a plant is average 40,2 pcs. The mass of 1000 seeds is 283,9 g /217-311 g/. The crude protein content in the grain is 23,15 %.

Resistance to stress. Ruse 1 variety is with a very good draught resistance. It has middle resistance to powdery mildew (Erysiphe pisi) and is resistant to ascochita (Ascochita pisi), bacterioza (Pseudomonas pisi) and fusarium (Fusarium culmorum, Fusarium solani, Fusarium oxysporum).

Productivity. Ruse 1 variety has very good productive abilities and stable yield. Average for the period 2004 – 2006 under conditions of IASS "Obraztsov chiflik" – Rousse, 342 kg/da were obtained, which is 30% higher than the yield of the standard Pleven 4.
