 ABSTRACT

Collaborative studies were conducted at Potato Technology Centre, Shamgarh, Karnal, India and in different districts of Haryana during 2018-19 to identify suitable varieties for semi-arid, agro-ecology of Haryana. First experiment was conducted at Potato Technology Centre, Karnal during 2018-19 to evaluate the clones/ varieties at for short duration maturity possibilities. The treatments included seven clones of potato from CIP and five popular varieties CPRI. The experiment was laid out in randomized block design with three replications. Sowing was done on 24 October, 2018 at a spacing of 60 cm x 20 cm. Dehaulming of potato crop was done at 75 days after sowing (DAS). Second experiment was conducted with 7 most promising CIP clones along with five popular varieties of CPRI in five selected districts of Haryana (Karnal, Kurukshetra, Rohtak, Sirsa and Mahendergarh) was laid out to explore the location specific clones. The experiment was laid out in randomized block design with three replications at each location. Sowing was done in October, 2018 at Karnal, Kurukshetra and Rohtak, and in November, 2018 at Mahendergarh and Sirsa. Spacing was 60 cm x 20 cm. Dehaulming of potato crop was done at 90 DAS.
By dehaulming at 75 DAS, maximum tuber yield was recorded with Kufri Mohan (40.6 t/ha), followed by CP 4393 7008 and Kufri Khyati (31.6 t/ha), indicating their suitability for short duration maturity. When dehaulming of potato was done at 90 DAS, variety Kufri Mohan resulted in highest tuber yield and ranked one in Karnal, Kurukshetra and Sirsa (40.6-50.3 t/ha); Kufri Khyati in Mahendergarh (42 t/ha) and CP 4404 7015 in Rohtak (38.6 t/ha).  The tuber yield of CP 4393 7008 and CP 4395 7010 was almost same in both the trials, indicating early maturity of these clones along with characteristics of late maturity. Highest dry matter (19%) was recorded in clones CP 4397 7011 and CP 4404 7015 with highest specific gravity (1.070) and total solid contents (19.2%), suggesting both the clones to be good as processing varieties. Characterization of elite clones of potato was also done.
