The main problem of dry bean production technology is harvesting. The harvesting systems depends on the growth habit. In the growing technology, which uses a low level of mechanization and harvesting is manual, the type of plant is not important, except when the morphology negatively correlates with productivity. The growth habit most suitable for direct harvesting with combine is growth type IIa, with an erect plant, located high and non-shattering pods, white seeds, resistant to economically important diseases. Moreover, varieties of this growth type are characterized by high yield in the highest stability. The erect plant provides better light penetration in the crop, better photosynthetic activity and higher productivity. It provides better crop ventilation, less problems with diseases and minimizes problems associated with frequent rainfalls during harvesting. Therefore, breeding at Dobroudja Agricultural Institute (DAI) - G. Toshevo is directed primarily to wards developing varieties of dry bean with this feature. Six varieties of dry bean have been developed with growth habit type IIa - Prelom, Abritus, Ludogorie,GTB-Ustrem, GTB-Blyan and GTB-Vezhen. Variety GTB-Skitiya was developed by Dimitar Genchev and Ivan Kiryakov, DAI G. Toshevo through repeated selection of individual plants in the cross DG 6-26 [DG 98-73-6 [Oreol / 769 // Prisad /3/ G2883 / Desislava /7/ SuavesINIA 88-57-A3 // 80-7-11-12 / G2883 /3/ Oreol /5/ Prelom / Zornitsa // Trudovets2 / Dagonovo83 /3/ Oreol /6/ GNStar / Garmen /8/ 80-7-11-4 / 84AR235 // Relom / 80-7-11-12] /8/ DG 5-36 [DG 1-66 [VAX3 /4/ DG 92-33 (80-7-11-12 / Prelom /3/ Prelom / Zornitsa // Trudovets2 / Dagonovo83)] /5/ DG 1-80 [AIYa /4/ Oreol / 769 // Garmen /3/ Prelom / Zornitsa // Desislava /]]]. The vegetation period of GTB-Skitiya is 84 4 d, 3 days more than variety GTB-Ustrem and GTB-Blyan, 6 days less than variety Dobrudjanski 7 and 5 days less than variety Beslet. The main stem and branches of variety GTBSkitiya end with a vegetative bud. The plant is without tendril and no lodging (IIa type). The hypocotyl is green. The plant height depending on environmental conditions is within 50 - 60 cm. The pods are located in the upper 4/5 of the plant. All this makes variety GTB-Skitiya suitable for direct harvesting. The leaves are green, medium rugosity, weak pilosity above and absent below, with a circular to quadrangular shape and a medium acuminate apex. The flowers are with white standard and wings, green keel and medium bract. The pods are medium long and medium width, elliptical to avoid, with small ratio of thickness:width, green, concave, medium curved, slightly truncate apex, with weakly rough texture of surface, medium long and medium curved beak. The seeds are white, with weak veining and medium glossines. Longitudinal shape is kidney, and cross shape elliptic. The weight of 1000 seeds is 411 18 g, and hectoliter weight is 76.4 1.2 kg. They are with very good taste and cooking time of 125 12 min. The protein content is 19.0 1.1%.
