The promising variety “Khanpur Canola” (KN-279) is an outcome of hybridization (KN-120 × Shiralli) durong 2006-07 and chosen through Pedigree strategy for determination. Homozygous descendants were built in 2014-15 for yield assessment. Its exhibition was assessed in on station, micro yield preliminaries and national level Uniform Rapeseed Yield Preliminary trials. It has demonstrated its worth in all yield preliminaries and its exhibition is superior to every one of the current developed assortments. Its greatest yield of 3400 kg/ha was accomplished in NURYT 2018-19. It produced 22% higher yield in micro yield trials against standard variety during 2016-17. It surpassed the check (Faisal Canola) with 21% better return in National Uniform Rapeseed Yield trials in 2017-18. Similarly, in NURYT 2018-19 KN-279 gave 19% higher seed yield than the check hybrid Hyola 401.Khanpur canola is a striking cultivated new endorsed assortment having great qualities and reasonable for palatable oil creation. It has the erucic acid; 4.04 % and Glucosinolates; 17.20 µ mole/g oil and it gives 40-46 % eatable oil content on extraction. Agronomic examinations uncovered that this assortment needs no unique creation innovation bundle and fit in a superior manner with the current agronomic practices. The competitor assortment additionally showed most extreme aphid resistance when contrasted with the actually agronomic practices. It is reasonable for climatic states of both inundated and rain-fed region of the Punjab.
Yield constancy is a crucial characteristic for a variety to become popular among growers. To study this aspect, the present trial was carried out at seven locations in the cotton belt of Punjab during 2020-21. Twenty-five upland cotton strains from different breeding stations were tested along with the standard variety CIM-602. The main objective was to choose super-yielding plus stable strains. Maximum variability due to environments (65%) followed by GEI (22.8%) was observed. The first two interaction principal components (IPC) were squeezed with 72.3% of cumulative variability due to GEI. The analysis of additive main effects and multiplicative interaction (AMMI) diagnosed AMMI5 as an appropriate model. Strain CKC-5 gave maximum mean yield (1812kg ha-1) and winner in all AMMI models. Test sites were split into two mega environments (ME). ENT7 (CRS Faisalabad) site was bearing the highest mean seed cotton yield of (2532kg ha-1) with the biggest (52.18) IPC1 score. The correlation between sites and IPC1 scores was (0.68) as recorded by AMMI analysis. AMMI1 ranks depicted that (PCI2) CIM-875 bears yield advantage of (29.09%) at ENT6 (Vehari) site over (trial winner strain CKC-5) due to micro adaptations. Genotype Selection Index (GSI) discriminated strain BS-J5 as yielder cum stable one with the least GSI value. Approval of this strain for general cultivation from the respective forum may boost cotton production in the province.
