Abstract. ABSTRACT<br/><br/> A field experiment was undertaken at the Main Agricultural Research Station, Dharwad during kharif season of 2023. Three populations viz 5 F2 population, 1 F3 population, 140 ICRISAT groundnut mini core collection, 17 advance breeding lines were evaluated for in-situ germination and productivity traits. All the population were irrigated after maturity and evaluated for in-situ germination at weekly intervals. Seven plants from cross Dh257 X Dh 86, nine plants from cross Dh256 X Dh8, nineteen plants from cross Dhanalaxmi X ICGV 06189, thirteen plants from cross Dhanalaxmi X ICGV 03043, 3 plants from cross TMV 2 X Dh256 were identified as tolerant for in-situ germination for 2 weeks.<br/>Mini core collection was evaluated in augmented design. Advance breeding lines were evaluated in randomized complete block design. Analysis of variance indicated presence of significance difference between genotypes. High GCV and PCV, heritability coupled with genetic advance over mean was observed for in-situ germination and productivity traits such as pod yield per plant, kernel yield per plant, hundred seed weight indicating that mentioned traits are controlled by additive gene action and improvement in selection can be done. High heritability along with low genetic advance over mean was observed for days to fifty percent flowering, sound mature kernel, days to maturity mainly because of presence of less variability indicating that these traits are non responsive for further improvement.<br/>ICG36, ICG118, ICG4670, ICG6263, ICG8106, ICG98091 from ICRISAT groundnut mini core collection DBG21, DBG22, GND29 from advance breeding lines were identified in-situ germination tolerant lines under spanish background. Desirable segregants identified from segregating generation can be used to develop lines which are in-situ germination tolerance. Identified lines/ segregants can be released as variety after multi location evaluation or else can be used as donors for in-situ germination tolerance.
