Plants generally showed variation in their response to changing environment. Fifteen genotypes were tested at five locations in Pakistan in the Kharif season 2006 to study their yield stability. Pooled analysis of variance and stability analysis were performed. The genotype (G) x environment (E) interaction and both variance due to genotypes and environments were significant. The partitioning of G x E interaction into linear and non-linear components indicated that both predictable and unpredictable components shared the interaction. Three stability parameters were computed to judge the stable and superior genotype. On the basis of these parameters, the top yielding genotype '2 (check) CGM-504' exhibited the stable performance over all five locations. Results also showed that the genotypes; BRM-288, NCM-257-2 and BRM-286 gave higher yield. But their performance was unstable due to high deviation from regression. Seven genotypes NCM-252-7, 2CMG-504, C1/95-3/45, BRM-286, BRM-288, NCM-257-2 and M-8 produced more grain yield than average yield. On the basis of results, 2CMG-504 was the most suitable and desirable genotype which showed stable yields at different sites. Source

"Fareed-06" is a high yielding and rust resistant variety of bread wheat with erect growth habit. It was released in the year 2006 for irrigated areas of Punjab. Fareed-06 originated from a cross between two genotypes PTS/3/TOB/LFN// BB/4/BB/HD-832-5//ON, (a high yielding line received from CIMMYT, Mexico) and GV/ALD'S'/ /HPO'S'BR-3385-3B-1B-0B (a local line resistant to rust diseases) at Regional Agricultural Research Institute (RARI), Bahawalpur. F1 to F4 progenies of this cross were advanced by pedigree method. Resistance against rusts (Leaf rust = 5R to 20RMR and Yellow rust = 10MS, RRI value of 8 for both leaf and yellow rusts and ACI values of 0.6 & 7.4 for both leaf and yellow rusts) and high yield potential (6000 kg ha-1) are the major attributes of Fareed-06 that make it a superior variety for its target regions. Fareed-06 is tolerant to wheat aphid and Helicoverpa armigera and responsive to fertilizer compared to the check varieties. The 1000-seed weight of this variety is 38-42 gm. Seed is amber in colour and contains 11.9-13.3% protein, 26.5% wet gluten, 9.5% dry gluten, 1.83% ash. Its flour yield is 68.4%. It has good chapati making quality. Plant type of Fareed-06 is erect with plant height 75-90 cm and droopy flag leaves. Auricle colour is white. Ear shape and colour is tapering and red. Its straw is soft. It completes heading in 75-85 days and matures in 110-120 days. Fareed-06 performs better in irrigated areas of Punjab when planted from Ist November to 15 December, keeping 125 kg ha-1 seed rate and 125- 100-75 kg NPK ha-1 are applied. It can be concluded that Fareed-06 is not only a high-yielder, possesses better quality traits and tolerant/resistant to all diseases and insect pests, but is also best suited in wheat-cotton-wheat rotation.

AaS-2011 is a high yielding and rust resistant variety of bread wheat with erect growth habit. It was released in the year 2011 for irrigated areas of Punjab. AaS-2011 originated from a cross [PRL/PASTOR//2236(V.6550/Sutlej-86)] attempted at Regional Agricultural Research Institute (RARI), Bahawalpur during 1997-1998. F1 to F5 progenies of this cross were advanced by pedigree method. Resistance against lodging, karnal bunt, stem rust (UG-99 a local race), spot blotch, rusts (Leaf rust = 10R to 30RMR and Yellow rust = 10R to 20MRMS, RRI value of 7.2-9.0 and 7.5-9.0 for leaf and yellow rusts, respectively) and high yield potential (6678 kg ha-1) are the major attributes of AaS-2011 that make it a superior variety for its target regions. AaS-2011 is tolerant to wheat aphid and responsive to fertilizer compared to the check varieties. The 1000-seed weight of this variety is 40-45 gm. Seed is amber in colour and contains 13.02% protein and 29% gluten. Its flour yield is 68.4%. It has good chapati making quality. Plant type of AaS-2011 is erect with plant height 95-105 cm with droopy flag leaf. Auricle colour is white. Ear shape is tapering and colour is red. Its straw is soft. It completes heading in 85-90 days and matures in 134-140 days. AaS-2011 performs better in irrigated areas of Punjab when planted from 1st November to 15 December, keeping 125 kg ha-1 seed rate and fertilizer dose as 150-120-60 kg NPK ha-1. It can be concluded that AaS-2011 is not only a high-yielder, possesses better quality traits, tolerance/resistance to regional prevailing diseases and insect pests, but is also best suited for wheat-cotton-wheat rotation system.

In this paper we report the release of a new wheat variety "Mairaj-08". It is a high yielding and rust resistant variety of bread wheat with erect growth habit. It was released in 2008 for irrigated areas of Punjab. Mairaj-08 is result of a local cross i.e., SPARROW/INIA//V.7394/WL711//3/BAU'S'. F1 to F4 progenies of this cross were advanced by pedigree method. Resistance against rusts Leaf rust=Tr. to 00MSS and Yellow rust=40 to 60MSS, RRI value of 8-8.9 for leaf and 3-6.7 for yellow rusts and high yield potential (7400 kg ha-1) are the major attributes of Mairaj-08 that make it a superior variety for its target regions. Mairaj-08 is tolerant to wheat aphid and Helicoverpa armigera and responsive to fertilizer compared to the check varieties. The hundred grain weight of this variety is 38-42.6 g. Seed is amber in color and contains 11.7-13.1% protein, 26-26.5% wet gluten, 8.2-9.2% dry gluten, 1.5-2.9% ash. Its flour yield is 69.9%. It has good chapati making quality. Plant type of Mairaj-08 is erect with plant height 90-95 cm and droopy flag leaves. Auricle color is white. Ear shape and color is tapering and red. Its straw is soft. It completes heading in 81-98 days and matures in 115-137 days. Mairaj-08 performs better in irrigated areas of Punjab when planted from 1 November to 15 December, keeping 125 kg ha-1 seed rate and 125-100-75 kg NPK ha-1 are applied. © 2010 Friends Science Publishers.
