PREFACE

All India Coordinated Research Project on Potato initiated in 1970-71 is operating through

17 State Agricultural Universities based centers, 7 ICAR-CPRI based centers and 1 voluntary

center.

In this 46th Annual Report of AICRP (Potato), experiments conducted during summer/kharif

2017 in hills/plateau and rabi 2017-18 in the plains have been reported. There were 11

experiments in Crop Improvement, 14 in Crop Production and 11 in Crop Protection at

various locations. Efforts have been made to collect, consolidate, analyze and compile the

data collected from those experiments in this report. Based on the pooled analysis of the

performance data of advanced hybrids, three promising hybrids have been identified and

are being proposed for release. Besides, three technologies related to Crop Production &

one related to Plant Protection have been identified and if recommended, will be passed on

to the respective State Department of Agriculture/Horticulture.

I would like to record my sincere thanks to Dr AK Singh, Deputy Director General

(Horticultural Science), Dr T Janakiram, Assistant Director General (Horticultural Science-I),

ICAR, New Delhi and Director, ICAR-CPRI for their keen interest in the programme, help and

guidance. I am indebted to my colleagues Dr VK Dua, (Head, Crop Production), Dr Vinay

Bhardwaj (Acting Head, Crop Improvement) and Dr Sanjeev Sharma, (Acting Head, Crop

Protection) for their help in compiling this annual report.

I am also thankful to Dr’s Jagdev Sharma, Paresh Chaukhande, Sushil Kumar, Name Singh, VK

Gupta, SK Luthra, Raj Kumar, Shambhu Kumar, Salej Sood, Vinay Sagar, Kamlesh Malik,

Mohammad Abas Shah, Anuj Bhatnagar, Baswaraj R and Ravinder Kumar for interpreting

the analyzed results and preparing write-ups of their respective disciplines for this annual

report. Dr Vinod Kumar, Principal Scientist and Mr Dharminder Verma, Assistant Chief

Technical Officer, AICRP Unit, CPRI, Shimla have been instrumental in compiling the

information and their efforts are greatly appreciated.

Statistical analyses by Mr Dharminder Verma, Assistant Chief Technical Officer; secretarial

assistances by Mrs Nirmala Chauhan, UDC; assistance provided by Mr Sita Ram, Sr

Technician and Mr Surinder Pal, Sr Technician in reprography are appreciated and thankfully

acknowledged.

GENET. 1: EVALUATION OF GERMPLASM 1.(b): EVALUATION AGAINST POTATO APICAL LEAF CURL DISEASE One hundred and five germplasm accessions including 70 CP nos. and 35 hybrids were evaluated against potato apical leaf curl New Delhi virus (PALCNDV) at Hissar. Twenty-two accessions viz., CP 4170, CP 4173, CP 4223, CP 4226, CP 4283, CP 4388, CP 4395, CP 4399 and CP 4406 were found highly resistant (≤10% infection) to apical leaf curl virus. Besides, 3 accessions namely CP 4222, CP 4245 and CP 8388 were found moderately resistant to PALCNDV (≤20% infection).

5-1 Kufri Shailja, Kufri Girdhari, Kufri Himalini, Kufri Giriraj and Kufri Jyoti were multiplied.


GENET. 4: ADVANCED VARIETAL TRIAL (AVT) WITH MEDIUM MATURING HYBRIDS Four advanced hybrids viz., PS/06-88, PS/5-75 (red skin) MP/6-39 and MS/8-1148 (white skin) along with the control varieties viz., K Khyati, K Pukhraj, K Ashoka, K Jyoti, K Garima, K Mohan, Kufri Ganga (White skin), K Lalima, K Lalit (red skin) were evaluated at 75 and 90 days durations in 35 trials at 18 AICRP centers though Pasighat evaluated for 75 days, while Kota for 90 days only during rabi season in the plains. Plant emergence was normal at most of the locations (>80%) except in Kufri Mohan (78% at 75 days), PS/06-88 (79%) at Bhubneshwar; Kufri Bahar (78% at 75 days) at Dessa, PS/5-75 (76/71%) and MP/6-39 (75/75%), MS/8-1148 (70/74%) at 75/90 days at Dholi, PS/5-75 (58%) and MP/6-39 (74%), MS/8-1148 (78%) at 90 days at Kalyani, MP/6-39 (60/59%) at 75/90 days at Kanpur, MS/8-1148 (76/76%) at 75/90 days at Pasighat. At most of the locations late blight did not appear or was not reported except Dholi (20 to 45%), Jorhat (100%), Kanpur (15-25%) and Pasighat (7.1 to 12.7%). Incidence of leaf spot (0 to 45.6% and viral disease (0 to 28.3%) were recorded at different locations. Red skin hybrid PS/8-88 outyielded the best controls (Kufri Lalit or Kufri Lalima) at Bhubaneshwar (75/90 days), Faizabad (75/90 days), Gwalior (75 days), Modipuram (75/90 days), Pantngar (90 days), and Patna (75/90 days). Another red skin hybrid, PS/5-75 out yielded the best controls (Kufri Lalit or Kufri Lalima) at Modipuram (75/90 days) and Patna (75/90 days). White skin hybrid MP/6-39 could not out yield the best controls Kufri Ganga, Kufri Khyati, Kufri Pukhraj, Kufri Garima and Kufri Mohan at most of the locations, However, it showed some yield increase over Kufri Bahar at five locations viz., Chindwara, Gwalior, Kanpur, Kota, Modipuram and Pantngar at 75/ 90 days crop duration. Another, white skin hybrid MS/8-1148 out yielded the controls Kufri Ganga (2 locations), Kufri Khyati (4 locations), Kufri Pukhraj (4 locations), Kufri Jyoti (4 locations), Kufri Garima (5 locations), Kufri Mohan (2) and Kufri Bahar (6 locations) at 75 days. Similarly, at 90 day it outyielded the controls, Kufri Ganga (1 locations), Kufri Khyati (6 locations), Kufri Pukhraj (8 locations), Kufri Jyoti (4 locations), Kufri Garima (9 locations, Kufri Mohan (1) and Kufri Bahar (7 locations). Advanced hybrids PS/8-88, PS/5-75, MP/6-39 and MS/8-1148 possessed nearly 18% tuber dry matter content at 90 days at most of the locations. The keeping quality studies at six locations namely Bhubaneshwar, Deesa, Modipuram, Pantnagar, Pune and Raipur indicated low total weight loss in PS/6-88 and PS/5-75 (4 locations), MP/6-39 (4 locations) and MS/8-1148 (3 locations) as compared to best controls Performance based on pooled data over locations PS/05-75: The hybrid could not perform superior than controls Kufri Lalima and Kufri Lalit in northern, central and eastern plains at 75 or 90 days crop duration. PS/06-88: The hybrid remained at par for total tuber yield in northern plains (75, 90 days) and eastern plains (75 days) as compared to control Kufri Lalima and Kufri Lalit. The hybrid yielded significantly higher for total tuber yield at 90 days in eastern plains as compared to control Kufri Lalima and Kufri Lalit. The yield hybrid showed significantly high total tuber yield at 90 days at Bhubaneshwar, Dholi, Faizbad and Patna as compared to controls Kufri Lalima and Kufri Lalit. The hybrid showed variable tuber dry matter content in northern plains (17%), central plains (18%) and eastern plains (21%). MP/06-39: The hybrid could not perform superior than controls Kufri Bahar, Kufri Khyati, Kufri Pukhraj and Kufri Ganga in Northern, central and eastern plains at 75 or 90 days crop duration. MS/8-1148: The hybrid showed at par performance with Kufri Bahar in northern plains at 75 and 90 days. In central plains it showed significantly superior performance as compared to Kufri Bahar, but remained at par with Kufri Pukhraj at 75 and 90 days. In eastern plains, the hybrid remained at par with Kufri Khyati and Kufri Pukhraj. The hybrid did not show any advantage over new variety Kufri Ganga in all the regions.
