Breeding wheat Genotypes for North-Western Plains

Project: Developing high yielding and climate resilient wheat varieties

Sub Project: Breeding wheat genotypes for North Western Plains of India

Genesis and rationale of the project:

3.1.0

Wheat in North Western Plain Zone occupies more than 11.0 million hectares of cultivated area. This zone contributes about 50% of India’s wheat produce. High productive and fertile environments of this region have been witness to ‘green revolution’. This region is now facing stagnation in total productivity of wheat and also there seems no scope to increase area under wheat crop. Also various biotic and abiotic stresses are threatening to bring down the yield levels. Wheat rusts, particularly yellow rust has always posed a serious threat to wheat crop in this region. The threats from other diseases such as Karnal bunt and leaf blight cannot be over looked. On the abiotic stress front terminal as well as early heat stress has been a concern in recent years. The high temperature during grain filling not only reduces yield but grain quality is also deteriorated. Rice-wheat cropping system is one of the most vital issues in Indian agriculture in this part of the country. In view of the increasing cost of inputs, stagnating yields, it is pertinent to reduce the cost of cultivation.Zero tillage has now emerged as one of the options in this regard. To harvest the gains from this technology it is important that a specific research approach be adopted towards development of specific varieties suitable for specific tillage conditions.

This wheat improvement program caters to the above needs and is devised keeping in view following objectives:

  1. Genetic enhancement for yield and its component traits in wheat
  2. Incorporation of multiple disease and insect resistance in wheat with focus on stripe rust, Karnal bunt and aphids
  3. Improving terminal heat tolerance and overall grain quality particularly micronutrient content
  4. Identification of genotypes with high lodging tolerance
  5. Evaluation and validation wheat genotypes under different tillage interactions
  6. Multi-location evaluation for identifying stable genotypes

 Major Achievements of the program

This is a long term wheat improvement program and aims to develop wheat genotypes with high yield and stability across the north western plains of India. At the same time focus is on identifying the stripe rust resistant lines with tolerance to lodging and terminal heat stress. This project is strengthened by inputs from other projects being operated at the institute such as, CSISA and Harvest plus programs of CIMMYT and ICAR-ACIAR collaboration for wheat improvement. Following wheat varieties have been released from this program for culivation by the farmers.

DBW 14 (Raj 3765 / PBW 343): Released byCVRC in 2003. Early maturing wheat variety for late sown, irrigated condition of North Eastern Plains Zone (NEPZ). This variety was first indigenously developed variety through shuttle breeding approach and is suitable for rice-wheat system of eastern India. A very popular genotype in NEPZ as replacement for HUW 234.

 

 3.1.1

DBW 16 (Raj 3765 / WR 484 // HUW 468): Released by CVRC in 2006. Early maturing wheat variety for late sown, irrigated condition of North Western Plains Zone (NWPZ). This indigenously developed variety has better resistance against yellow and brown rusts and leaf blight along with yield superiority. It is suitable for wheat based cropping systems of north western India.

 

 3.1.2

CBW38(CNDO/R143//ENTE/MEXI_2/3/Ae. sq(Taus)/4/WEAVER/5/2*PASTOR):Released by CVRC in 2008. Wheat varietyfor timely sown, irrigated condition of North Eastern Plains Zone (NEPZ). This variety has yield advantage over all the checks and candidate varieties and possesses APR to yellow rust race 78S84.

 

 3.1.3

DPW621-50(KAUZ//ALTAR84/AOS/3/MILAN/KAUZ/4/HUITES):Released by CVRC in 2010. Wheat varietyfor timely sown, irrigated condition of North Western Plains Zone (NWPZ). This variety has better yield advantage and possesses APR to yellow rust.

 

3.1.4

DBW 90 (HUW 468/WH 730): Released by CVRC in 2013. Early maturing wheat variety for late sown, irrigated condition of North Western Plains Zone (NWPZ). This indigenously developed variety has better resistance against yellow and brown rusts and leaf blight.

 

 

3.1.5

WB2(T. dicocccon C19309/Ae.sq(409) /3/MILAN/S87230//BAV92/4/2*MILAN/S87230//BAV92): Released by CVRC in 2017. WB 2 has shown yield superiority over the check variety DPW 621-50. It possesses high Zn & Fe content in grain. It is also resistant against prevalent yellow rust pathotypes 78S84 and 46S119.
