Abstract:
A field experiment was conducted during 2002 at CCS University, Meerut to study the effect of environmental factors and seasons on field emergence, growth and seed yield in Six inbreds/OPVs: CM135, CM136, CM137, CM138, CM500, CM600 and two single crosses: CM202xCM111 & CM400xCM300 were evaluated for five characters namely, field emergence, rate of field emergence, seedling dry weight, seed yield and 100 seed weight. Result revealed that field emergence, its rate and seedling growth were better in kharif than in spring-summer season. Seed yield and 100 seed weight were maximum in spring-summer than in kharif season. Inbred lines (CM135, CM136, CM137 and CM138) and the single crosses (CM400xCM300& CM202xCM111) showed high field emergence in both the seasons. Single crosses (CM400xCM300 & CM202xCM111) give highest yield while parental lines CM600 and CM500 had lowest seed yield and 100 seed weight.
