Phule Satwik (NIAW 3170): A soft bread wheat variety for North Western Plains and Peninsular Zone of India

Wheat is an important crop that plays major role in a food grain production in the country. It is a lone source for industries involved in the manufacturing of bread, biscuits, flakes, cakes etc. These industries rely on quality parameters viz ., grain hardness index, biscuit spread factor, bread quality score, and bread loaf volume. Bread wheat variety Phule Satwik (NIAW 3170) is developed at Agricultural Research Station, Niphad has been released and notified by Central Sub Committee on Crop Standards, India for cultivation in North Western Plains Zone and Peninsular Zone under restricted irrigation conditions vide notification number S.O. 3482 (E) dated 7 th October, 2020. The variety has high yield potential under restricted irrigation conditions along with disease resistance and superior grain quality parameters. It was the softest grain variety among all the genotypes having a biscuit spread factor of more than 10. With good nutritional and quality parameters, it will be a promising variety for bakery industries.


Introduction
Wheat (Triticum aestivum L.) is the second major rabi-cereal crop in India.It plays a crucial role in food grain production in the country.India ranks second in the production of wheat in the world.In India during 2022-23, the wheat was cultivated on 32.44 million ha with the production of 112.74 million tonnes. 1 In India, wheat is mostly consumed in the form of chapatis and roti.It is one of the major sources of diet which provides nearly half of the dietary protein and more than half of the calories to the Indian population.
It is an important source for industries involved in the manufacturing of bread, biscuits, flakes, cakes etc.These industries rely on quality parameters viz., grain hardness index, biscuit spread factor, bread loaf volume, and bread quality score.Gluten a protein present in wheat is an important ingredient in bakery products because of its high elasticity, viscosity, and swelling power.It is a rich source of phosphorous and also increases the shelf life of bakery products.Considering these points, continuous efforts resulted in the development of a bread wheat variety Phule Satwik (NIAW 3170) which will be preferred by the biscuit industry.It was developed at the Agricultural Research Station, Niphad (MS), and was identified and recommended by the Varietal Identification Committee Meeting in the 58th AGM of AICRP on Wheat & Barley.It has been released and notified by the Central Sub-Committee on Crop Standards, India for cultivation in NWPZ and PZ under restricted irrigation conditions.

Material and Methods
Elite Germplasm Screening Nursery received from International Maize and Wheat Improvement Center (CIMMYT), Mexico was sown during Rabi 2012-13 at Agricultural Research Station, MPKV, Niphad.Entry no 59 having the pedigree of SOKOLL X ROLF 07 was selected and evaluated in Station Trials viz., Rod Row Trial and Progeny Row Trial during rabi 2013-14 and 204-15 respectively.Based on performance the genotype was further advanced and evaluated in Multilocation Varietal Trial at three different locations viz., Niphad, Rahuri, and Saval Vihir during rabi 2015-16.On basis of performance, it was promoted and evaluated in the National Initial Varietal Trial (NIVT-5A-RI-TS) at 31 locations in NWPZ and PZ during rabi 2016-17.The genotype was promoted to Advanced Varietal Trial-1 (AVT-RI-TS-PZ) and was evaluated at 16 and 11 locations in NWPZ and PZ respectively during rabi 2017-18.It was promoted to Advanced Varietal Trial-2 (AVT-RI-TS-PZ) and was evaluated at 23 and 17 locations in NWPZ and PZ respectively during rabi 2018-19.The severity of rust and its response in the field was recorded with score of 0-100 scale. 2 For statistical analysis, the rust reactions were transferred into a coefficient of infection (COI). 2 Gene postulation for rust resistance genes was done at the seedling stage scoring 0-4 scale. 3The Distinctiveness, Uniformity, and Stability (DUS) characterization of NIAW 3170 was done following the guidelines given by PPVFRA.

Varietal Descriptors
NIAW 3170 has having semi-erect growth habit, pale green foliage colour, waxiness is present on flag leaf, leaf sheath, ear head, and peduncle.It has an average plant height of 78 cm, flowers in 44 to 71 days, and matures in 98 to 120 days.The ear head is tapering, white, long with medium density and short awns.It has white-colored, oblong shapes with very soft textured seeds with an average test weight of 39 g

Yield Evaluation
The performance of NIAW 3170 was tested in station trials viz., Rod Row Trial (2013-14) and Progeny Row Trial (2014-15) under restricted irrigation conditions.It ranked first with an average yield of 34.08 q ha -1 .Then it was tested in a University Multilocation Trial during 2015-16 at two locations viz., Niphad and Rahuri.
Evaluation in Peninsular Zone trials NIAW 3170 was included and evaluated for three years i.e. 2016-17 (NIVT-5A-RI-TS-PZ), 2017-18 (AVT-I-RI-TS-PZ) and 2018-19 (AVT-II-RI-TS-PZ) under All India Coordinated Wheat Improvement Programme.It showed stable and high-yielding performance under restricted irrigation conditions at various locations of the Peninsular Zone as compared to the checks DBW 93 and HI 1605 (Table 1).In NIVT-5,NIAW 3170 (44.3 q ha -1 ) significantly outyielded the check DBW 93.In AVT-I during 2017-18 NIAW 3170 recorded a yield of 31.1 q ha -1 which was statistically superior over all the checks of the zone.In the last year of its evaluation, in AVT-II (2018-19) it recorded 35.0 q ha -1 of yield which was again significantly superior over all the checks.The variety NIAW 3170 was found superior over the checks DBW 93 and HI 1605 with 20.3 % and 19.5 % increase over the mean and 15.4 % and 9.4 % over the weighted mean respectively.The frequency of occurrence of NIAW 3170 in the top non-significant group was the highest among all test entries and checks.It was 14/17 in a top non-significant group on the overall basis of three years as compared to the checks DBW 93 (5/17) and HI 1605 (7/16) 4,5,6 The yield potential of NIAW 3170 (44.3 q ha -1 at location ARS, Niphad, 2016-17) was highest when compared with all the checks (Table 1).

Evaluation in North Western Plains Zone Trials
In NWPZ trials the entry NIAW 3170 was evaluated for three years i.e. 2016-17 (NIVT-5A-RI-TS-NWPZ), 2017-18 (AVT-I-RI-TS-NWPZ) and 2018-19 (AVT-II-RI-TS-NWPZ).It showed high-yielding performance under restricted irrigation conditions at various locations of NWPZ as compared to the checks WH 1142, WH 1080, PBW 644, HD 3043, HD 3237, and HI 1620 (Table 2).In NIVT-5 it yielded an average of 54.7 q ha -1 which was significantly superior over the check WH 1142.In AVT-I during 2017-18, NIAW 3170 has given an average yield of 48.5 q ha -1 which was significantly better over all the checks of the zone.In the final year of its testing, in AVT-II (2018-19) it recorded 50.1 q ha -1 of yield which was significantly superior to the checks viz., WH
