Response to Selection for Seed Cotton Yield of (Giza 95 x Super Giza 86) Egyptian Cotton Cross under Newly Reclaimed Lands Conditions
Selection for seed cotton yield plant-1 in a segregating population of cotton of cross Giza 95 x Super Giza 86 was applied under new reclaimed lands conditions for three summer season, 2019, 2020 and 2021 at Mallawy Agriculture Research station, west of El Minia. The wide range of seed cotton yield/plant in the F2-generation from 16.40 to 186.00 gm. Indicating ability effective selection for seed cotton yield. Entries mean squares of the selection criterion; seed cotton yield and lint yield/plant and number of bolls/plant were high significant in F4-generation. Estimates higher than 82.71% of heritability for the seed cotton yield, lint yield/plant and branches/plant. Two families; No. 6 and 9 were higher than the better parent Giza 95 and bulk sample in each of seed cotton yield, lint yield/plant and number of bolls /plant in the F4-generation. Four selected families no. 2, 6, 9 and 20 were showed significant (p≤0.05 or 0.01) increase compared to the bulk in seed cotton yield/plant by 19.26, 50.03, 32.16 and 64.26%, respectively. The seed cotton yield per plant showed strong positive genotypic and phenotypic correlation with each of lint yield per plant by 0.99 and bolls number/plant 0.97 and 0.95, respectively. Moreover, low positive correlation with boll weight, seed index, fiber length and uniformity index, with negative correlation with each of lint percentage, fiber fineness, lint index and fiber strength.
