Phenotypic stability for yield and quality factors in spanish bunch groundnut (Arachis hypogaea subsp fastigiata var vulgaris)

Abstract

An experiment was conducted during 2 rainy (kharif) and 2 winter (rabi) seasons and 1summer season (starting from rainyseason 1989) to study the performance of 10 varieties of spanish bunch gruundnut (Arachis hypogaea L. ssp fastigiata Waldronvar vulgaris Hartz) for pod and kernel yields, shelling (%). sound mature kernel (%) and 100·kernel weight. The differencebetween the varieties was significant for shelling (%). sound mature kernel(%) and 100·kernel weight. On the basis of 5characters, varieties 'Kisan', 'Jawan', 'Girnar 1' and 'OG 52-1' were found superior to the others by 26%. 10 general. 'ICGS11' was found stable for 4 characters (pod and kernel yields, 100·kernel weight and sound mature kernel %) and 'Kisan'.'Jawan' and 'ICGS 44' for 3 characters (pod and kernel yields and sound mature kernel %), whereas tha remaining varietieswere found stable for 1 character each.
