Abstract

The development of new crop varieties is a continuous process as old cultivars become susceptible to various biotic and abiotic stresses, thus decreasing the yield potential. The newly developed rapeseed variety “Barani Sarsoon” a high-yielding, disease resistant and drought tolerant has been developed through the selection method of breeding from the exotic material. A promising progeny of a single plant was selected and named “14CBN009”. The performance of “14CBN009” was further evaluated along with standard varieties in various replicated yield trials for six years from 2014-15 to 2018-19. The selected line “14CBN009” produced a higher grain yield (kg/ha) than the standard varieties in all replicated yield trials with a yield potential of 3378 kg/hectare which is tolerant to drought and resistant to diseases. The best sowing time for this variety is from 25 th September to 15 th October with a seed rate of 2.50 kg/acre. The seed contains 44.53% oil content. The main yield contributing characters of “14CBN009” are pods per plant, seeds per pod and thousand-seed weight. Based on the desirable phenotypic and genotypic characteristics, higher grain yield and oil content percentage, “14CBN009” was approved as a rapeseed variety with the name of “Barani Sarsoon” by the Punjab Seed Council in its 55 th meeting held on Sep 20, 2021, for commercial cultivation in the Punjab rainfed areas. Due to high yielding, drought and disease-tolerant characteristics, the new variety “Barani Sarsoon” will prove to be a good alternative to existing varieties and improve the production and income of the oilseed crops growers of the rainfed area.

Research Objective

To develop and evaluate a new rapeseed variety, "Barani Sarsoon," with high yield, disease resistance, and drought tolerance for rainfed agricultural areas.

Methodology

The study involved the selection of a promising progeny from exotic rapeseed material, designated "14CBN009." This line was evaluated in replicated yield trials for six years (2014-2019) under rainfed conditions. DNA fingerprinting was performed using SSR markers for genetic uniqueness. Quality parameters were analyzed using Near Infrared Spectroscopy (NIRS). Agronomic trials determined optimal sowing times and fertilizer requirements. Plant protection trials assessed disease resistance. Statistical analysis was conducted using statistix 8.1 software.

Discussion

The development of "Barani Sarsoon" addresses the need for improved oilseed crop production in Pakistan, particularly in rainfed areas affected by abiotic stresses like drought and climate change. Its superior yield potential, disease resistance, and high oil content make it a promising alternative to existing varieties, potentially improving farmer income. The genetic distinctiveness confirmed by DNA fingerprinting ensures its uniqueness.

Key Findings

The developed rapeseed variety "Barani Sarsoon" (14CBN009) demonstrated higher grain yield (up to 3378 kg/hectare) compared to standard varieties. It exhibits tolerance to drought and resistance to diseases like powdery mildew and Alternaria blight. The variety has a high oil content of 44.53%. The optimal sowing period is from September 25th to October 15th, with a seed rate of 2.50 kg/acre. Key yield contributing characters include pods per plant, seeds per pod, and thousand-seed weight.

Conclusion

"Barani Sarsoon" is a high-yielding, drought-tolerant, and disease-resistant rapeseed variety with desirable genetic characteristics, approved for commercial cultivation in Punjab's rainfed areas. Its adoption is expected to enhance oilseed crop productivity and profitability for growers.

Fact Check

* The variety "Barani Sarsoon" was approved by the Punjab Seed Council in its 55th meeting held on September 20, 2021.
* "Barani Sarsoon" has an oil content of 44.53%.
* The optimal sowing time for "Barani Sarsoon" is from September 25th to October 15th.
