KS-103, a new soybean variety developed from the cross JS-335 x EC-241780 at Agricultural Botany Division, RCSM College of Agriculture, Kolhapur (Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra) identified in annual group meeting held at Jorhat (Assam ) for Southern Zone comprising Maharashtra A.P. , Karnataka and Tamil Nadu with IC number- IC 613905. The Variety is released on the basis of high Yield-25.37 q/ha. (Average yield of co-ordinated trials for South Zone) and better leaf rust tolerance compared to existing varieties. The variety KS-103 is having 12.4 gms 100 grain wt. For development of this variety back cross (BC2) method was followed by pedigree method. It is non lodging and fertilizer responsive recommended for irrigated and rain fed ecology of Kharif Season of South Zone and early maturity group which takes 91-95 days for maturity. This variety is also suitable for late sown conditions i.e. up to end of June. As far as reaction to diseases and pests is concerned, it is having better field rust tolerance and resistant to pest complex. The plant height of the genotype was 61.23 cm. The genotype KS-103 was taller than JS-335 with semi-erect growth habit and more spreading than check variety JS-335. Recommended seed rate for this variety is 75 kg/ha. The grains are yellowish white with 18.10 per cent oil and 45.56 per cent protein. The variety is superior in yield over check varieties viz. Bragg, RKS-18 and MAUS-61 and qualified varieties DSB-20 and RKS-63. The growth habit of the variety is semi-determinate and takes 39 days for 50 per cent flowering. Leaf shape round ovate with dark green colour. Flower is violet, leaf and pod pubescence is absent. Pod colour at maturity is brown and seed shape is rounded with light brown hilum colour.
