GENOTYPE × ENVIRONMENT INTERACTION AND ESTIMATION OF STABILITY FOR FOLIAGE YIELD OF SOME CASTOR GENOTYPES (RICINUS COMMUNIS L.) SUITABLE FOR ERICULTURE

摘要

Eri silk contributed to 12% of the total raw silk produced in India. The eri-sector of labour-intensive Indian sericulture pivoted on castor for foliage to rear eri silk worm. The relative ranking of foliage yield of 10 promising castor genotypes differed when compared over five macro-environments at Central Sericultural Research and Training Institute, Berhampore, India. Genotype × Environment interaction for castor foliage yield. thus far not reported till date, is presented herein for the first time. The study led to comprehension that five castor genotypes namely RG 2824, RG 2717, NBR 1, CSRS 1 and Talap Green can be considered as adaptable for yield stability. RG 2717 is expected to be the most stable among these castor genotypes studied with regard to foliage yield across both the favourable as well as unfavourable crop seasons.
