Accumulating polygenes for partial resistance in barley to barley hordeum vulgare leaf rust puccinia hordei 2. field evaluation



Accumulating polygenes for partial resistance in barley to barley hordeum vulgare leaf rust puccinia hordei 2. field evaluation



Euphytica 34(1): 15-20



Eight lines [Hordeum vulgare] from the the cross between cv. Vada and Cebada Capa with long to very long latent periods and 4 barley cultivars representing the known range of partial resistance to barley leaf rust were evaluated in the field for partial resistance and in the greenhouse for the latent period (LP) in the young flag leaf. Each of the 12 entries was sown (April 15, 1983) on a plot of 1.0 m2. There were 4 relicates. To reduce interplot interference the plots were separated from each other by 4.0 m of spring rye. The number of urediosori per tiller was evaluated at 27-6, 4-7, 12-7 and 10 days after heading. The LP was measured on 10 to 15 plants per entry in 1982 and on 10 plants in 1983. The levels of partial resistance varied greatly. The difference in number of sori per tiller between the most susceptible cultivar, Akka, and the most resistant cultivar, Vada, was about 50 times. Between Akka and the most resistant line this was approximately 5000 times. The LP's varied similarly: Vada had a LP 64% longer than that of Akka; the LP of line 26-6-11 was 15% longer. The range of partial resistance has been extended more than 2-fold. The correlation coefficients between LP and the level of barley leaf rust, expressed in transformed scale units, varied from -0.99 for the first sampling date to -0.97 for the third sampling date. Sampling the same development stage, 10 days after heading, did not improve the r-value (r = -0.98). The LP evaluated in the young flag leaf is shown to be a very reliable criterion for partial resistance in the barley-P. hordei pathosystem. Earliness tends to be associated with susceptibility. The correlation of days to heading with LP was 0.63, and with the level of barley leaf rust in the field -0.64.
