testing value for cultivation and use of negin pinto bean cultivar applying for commercialization

In this experiment, candidate pinto been cultivar (negin) along with 4 control cultivars (sembol, sepehr, saleh and kusha) were studied in 3 locations (khomein, ardabil and esfahan) based on complete randomized block design in 4 replications during two crop seasons (2021-2022 and 2022-2023). results showed that flowering occurred significantly earlier in negin candidate cultivar (42.3 days) than control cultivars. seed ripening in negin candidate cultivar happened 5 days earlier than determinate control cultivars (mean ripening period 82.1 days) and 12 days earlier than undeterminate control cultivars (mean ripening period 89.5 days). in all three study locations, sembol determinate cultivar had the highest hundred seed weight (52.98 g) and after that the other determinate cultivars (negin and sepehr) had the highest hundred seed weight (48.92 g and 46.53 g respectively). seed yield of determinate candidate cultivar (4235.8 kg/ha) was significantly more than other determinate sepehr and sembol cultivars (4027.1 kg/ha and 34463.8 kg/ha respectively) and seed yield of negin cultivar had not significant difference with seed yield of undeterminate saleh cultivar. finally, negin candidate cultivar can play an effective role as new germplasm in the country s bean production due to its erect type and ease of harvesting, early maturity and consumption of one to two times less water, marketability and production of larger seeds.
