Not Availablediscriminant function study on twenty-eight groundnut cultivars for seed yield revealed a progressive increase in the relative selection efficiency based on two , three and four characters over straight selection or single character selection index in both Purulia and Midnapur districts of West Bengal . But this trend is not true for five-character combination. Maximum efficiency was observed with the selection indices based on the four characters, viz,number of pods/plant, pod yield/plant , harvest index and seed yield/plant in both the environments. Maximum emphasis should be given to these four character during selection for higher seed yield in groundnut. These four character also recorded higher positive b value.Not Availabl

Not AvailableSeven hundred sixty eight Spanish bunch groundnut germplasm were screened for earliness using eight short duration elite cultivars as check in the field condition during rainy season 2001. The population showed wide range of variation for pod weight per plant, kernel weight per plant, shelling percent, hundred kernels weight and pod maturity percent recorded at eighty days Alicia germination (DAG). Forty-two genotypes recorded more than seventy percent pod maturity at eighty days after germination. Sixteen genotypes out of forty-two selected genotypes confirmed their carlincss in next post rainy season also having other desirable agronomic characters. These short duration germplasm would be useful as such or in the breeding program as donor parents.Not Availabl

Not AvailablePeanut plays a key role to the livelihood of millions in the world especially in Arid and Semi-Arid regions. Peanut with high oleic acid content aids to increase shelf-life of peanut oil as well as food products and extends major health benefits to the consumers. In peanut, ahFAD2 gene controls quantity of two major fatty acids viz, oleic and linoleic acids. These two fatty acids together with palmitic acid constitute 90% fat composition in peanut and regulate the quality of peanut oil. Here, two ahfad2 alleles from SunOleic 95R were introgressed into ICGV 05141 using marker-assisted selection. Marker-assisted breeding effectively increased oleic acid and oleic to linoleic acid ratio in recombinant lines up to 44% and 30%, respectively as compared to ICGV 05141. In addition to improved oil quality, the recombinant lines also had superiority in pod yield together with desired pod/seed attributes. Realizing the health benefits and ever increasing demand in domestic and international market, the high oleic peanut recombinant lines will certainly boost the economical benefits to the Indian farmers in addition to ensuring availability of high oleic peanuts to the traders and industry.Not Availabl
