Achievements: 

1. Arka Swadesh: Variety release for production of cut flowers under protected cultivation. Shining foliage and  flowers of attractive red color.  Flower production starts 6 months onwards from planting. High yielding capacity of 145 fl stalks/sq.mt/year.   Long stalk flowers with an average stalk length of 65-70cm. Medium sized flowers are produced with good keeping quality (6 days).
